PTA is blocking the IP addresses by black holing addresses to and from
them. Hence the mess that results after a false alarm is generated.

I heard Transworld backbone traffic suffered some big dips due to this
as a lot of their customers' IP got affected. May be Hasan/Amir can
confirm/deny this.

Internet in Pakistan has grown from nothingness to a respectable
10+Gbps affair. Almost like the fifth province if you will. It's sad
to see if falling in a mess too. :|

My two pennies:

 

This IP blocking is an extension of the same senseless thing that Etisalat does in the prison they call UAE. Once they bought PTCL they pressured the Pakistan government to stop issuing licences for anything and the government quite happily went and gave verbal order (since this was against the written policy!) to PTA to stop new licences. This was specifically meant to target Zong (China Mobile) from getting an LDI licence, when all the other cellular operators have this facility within their own group. This is causing a lot of diplomatic crisis between Pakistan and China and despite the PM signing a document asking PTA to issue this, a phone call still stalls this. You can see a part of the manifestation of this and many other slights we have been giving China by the way Zadari was treated this time in China.

 

These mysterious phone calls are also the cause of this promiscuous IP blocking, despite the deliberate windfall the grey market operators are getting from the increase in international termination rates. I am sure when one makes an analysis of the incoming traffic and compares this with the earlier volumes, then calculates the money to be coming in from APC for the USF, prepare to be surprised at the outright theft taking place. Also mysteriously, the vigilance of this illegal traffic is quietly gone to sleep as the people involved do not want to be caught by some poor underling who can then trace these back to their relatives.

 

This VoIP blocking is a part of the same crazy, senseless and silly exercise. I wish we would finally have someone in the government that was really interested to see the damage being done to the industry and growth of technology use by the common man by such actions: by default and by design (e.g. 31% tax on all phone calls, tax on cell phones making this no longer a common man’s tool)…

But if Naurus is any bit intelligent, it should be able to distinguish between the occasional MSN/Yahoo/Google voice chat user and the bulk grey market operator.

 

Or am i expecting too much common sense and intelligence from PTCL?

Agreed with Faez, Grey Traffic market follows "where there is a will
there is a way".
PTA takes one step ahead and illegal voip Guru'z make ten steps ahead.
End of the day, who suffers.....
We are going "back to the future"..

Narus is a detector (albeit in some ways limited). It cannot inject back anything into the system in real-time. Almost all HSA (High-Speed Analyzers) do this. For all those willing to use VoIP (on Messenger/Yahoo!, etc.) I suggest Skype (including for chat too). Skype is encrypted, and Skype can tunnel thru valid ports. Also, Skype continually updates it software so the default signature providers like narus and the like have, go out dated very quickly. All DPI specialists can ONLY detect Skype, but not to anything with it. Well like of ellacoya, etc. can take action upon detection by virtue of simulated policy-based routing so to speak.

For those who are saying its not a Narus issue, let me elaborate. If someone has set up a VoIP gateway (illegally), then narus can only detect the Source IP/Dest IP. Becuase this is the only information that is provided, and passed on to PTA, the destination IP is blocked. Case resolved (as far as PTA is concerned).

If they had the calling Party A and B number they can take much further action, by deactivating the SIM box, or telco/Wireless phone line rather than blocking the dynamic IP. IPs are plenty. SIMs/Telephone lines are a few. Makes sense to block the latter than the former.

PTA is basically very tired of Narus (sorry for the Narus bashing, but hey its coming) due to the Clearing House Project. They (PTA) have had some major issues with Narus. What PTA needs to do is to start an RSS list and update IPs, policies, etc. notifications that keep coming out, orders, to block IPs or websites, so that a uniform platform exists to address it.

I think the only prudent thing is to 'write' to PTA (have something in writing) and then pursue it with them. They are a Govt. entity, and in return public-servants, they need to behave as such, and not think of themselves as high-demi-Gods in any case. Some still do within PTA. If it were up to PTA they would like to charge you a paisa for every URL you access (they've reduced themselves down to a money making machine at our expense). This VoIP issue has gone out of control... Remember it was not long ago when Faisal Chohan (sic?) episode happened.

I again would reiterate that you need to put pressure on PTA in writing (and ask them to reply back in detail with a clarification). This is a good enough starting point.

We intend to send the following communication to our customers to explain the situation to them. Fellow providers please feel free to copy paste for consistent messaging across the end users:

Dear Customers,

During the past few days, some of you faced connectivity issues. These issues had their origin in IP connectivity not functioning as expected. ISP_NAME would like to explain the situation to its valued customers.

Pakistan Telecommunication Authority (PTA) has recently implemented a technical facility to monitor and mitigate illegal VoIP (Voice over IP) traffic. The services is said to be intelligent enough to actively monitor and analyze the traffic and take automatic actions subsequently to curb the illegal traffic.

Besides the regulatory orders sent to every licensed ISP for the filtering and restriction of standard voice (SIP and H.323) ports, the authority now monitors the traffic and finds matching patterns that can possibility be voice packets. Users using Internet for voice without proper license are detected by their IP addresses and the facility automatically blocks these IP addresses. All kind of traffic for such users is blocked.

The current situation can also affect entire organizations where the network is behind a NAT device and the action of a single user in the organization can adversely affect the entire organization because the outside IP address gets blocked by this active monitoring system.

We have also observed that it is likely that besides the standard ports, the system has also started to monitor and block usage of VPN, SSH and SSL which might not necessarily be related to voice activities.

ISP_NAME and other service providers in the industry have taken up this issue very strongly with the PTA. We have based our argument on the misery of the end users who are not involved in any kind of illegal VoIP operations and who are being subjected to connectivity outages due to the reckless use of the facility. The industry association will also try to highlight the issue in the media to build up the pressure to fix this wrong that is affecting our valued customer.

This is loads of cobblers, how can a third party or regulatory authority is responsible for taking action on something which originated from a responsible/Registered ISP. Surely this the wrong way to do things! Are PTA not able to talk to ISP's on how to implement policies and procedures or is it the case the ISP's are just showing PTA the finger? Surely the role of a regulatory body such as PTA should be to regulate ISP's not users...... ISP's should regulate users. If PTA can take actions against ISP's on complaints then it would be much better and easier where ISP's are able to track down individuals responsible and take action against them. Is it just me seeing all this being done wrong?

@ Mr. Rizwan. You are absolutely right that PTA should be regulating
ISPs. Let's assume that they have well set "policy" and they are going
to penalize ISP for any voice activity from their CIDR. Before being
penalized "the" regulator should provide a detailed report. Hmmmm
that's missing :) if IP is blocked than ISP should be intimidated
immediately to catch the user, again that's missing. And "the"
regulator should provide the criteria to the ISP on which they are
checking the traffic. Atleast I haven't seen any such criteria.

Sir jee, at the end of the day who is suffering ISPs and end-users.
Point is that if there is policy than all ISPs will abide by that but
sir where is the policy :)

You have no idea how much annoyance ISP are facing everyday. ISPs are
the one who wants to resolve the matter, ironically "the" regulator is
not doing anything to clear the mess in anyway.

Again its my opinion and could be wrong. My appologies just in case am wrong :)

Good points there Rizwan, but are you actually aware that who we are talking about here (sarcasm again) these are the great people of the telecommunication authority, they don't even know how to ……………… (guys fill this up yourself, use your imagination).

 

I really wish that they would have talked about that before doing such actions. They are least bothered about as mentioned we previously in the same mailing list that this to have that aristocratic attitude towards things.

Hi,

You mean that each ISP should install Narus or any alternate deep
packet analyzer at its own cost?

I think its lot better that PTA should check traffic, inform ISP about
IP, get customer info from ISP
and raid the customer using its own means and resources and ISP should
NOT be held responsible for this.

What if I start VoIP on PTCL Internet backbone? would PTA penalize
PTCL then?

What if I start grey traffic on Mobilink numbers (almost 90% of
International Calls are coming via Mobilink now a days)
would PTA suspend Mobilink's GSM License the way they did with a small
company like brain tel?

This is the country of discrimination and lawlessness, Salman Ansari
sahab well said that big giants dictate authority,
small local companies gets removed by such dictations.

Sorry if my message hurts someone's feelings.

Regards,
Z

Sims of any operator can be used - tellular devices and gsm gateways
are available openly in the market.

How come an operator (cellco) can stop it ??? If I install a channel
bank and use sims of mobilink will mobilink we be able to understand
that behind that I am terminating an international call ??

I agree that ingredd and egress should be the points to check the
traffic and I am all for it however before implememting such systems
and policies the implications should be studied. Having dpi and
automated blocking could be a solution but blocking secure ports in
just assumtion that they are in use for voice terminations is some
very very foolish.

Today its ssl tommorow it could be any VPN - GRE or ipsec tunnel ports
- is this really a solution ?

I think more reason able approach would be to implement dpi and have
blocking done by having proper sniffing for both A and B part -
implementing a half baked solution and trying to rectify the grey
traffic issue is useless.

Some mentioned implementing these solution at ISP site!!!! Come on
this is what we are confronting since begining as industry , believe
me it doesn't make commercial sense. It has to be at xchange leve
(IX) not at all at ISP site.

Subject: RE: Erroneous Blocking of IP Addresses by PTA....

Chairman
PTA
Islamabad

Dear Sir,

We’ve brought the situation to your kind notice many times. Previous
blocking of our legitimate IP addresses by PTA (our mail server, DNS
server and office LAN) has also gone unanswered without any proof or
evidence provided to us.

All other ISPs are facing similar issues and we’re very upset on this
state of affairs. ISP’s of country are being direct victim of this
PTA’s blocking “facility” which has become an “inability” for the
Internet users in the country.

This unilateral move of PTA is resulting in serious loss of business
and reputation to the ISPs. ISPs have now to cope with increased
number of yelling customers whose services get blocked by PTA without
any notification, degraded quality of services and running around
after PTA in getting services unblocked. Everything adds to increase
in operational cost and decrease in revenues. This situation should
not continue as such.

PTA’s role is of facilitator and enabler and not service blocker.
Inherited services of Internet should not be blocked without proper
proof and evidence of some illegal activity. PTA has also shifted the
burden of proof to ISPs in order to benefit LDIs. Mobile and fixed
line operators who are the actual source of local call termination/
origination are given free hand without any check and balance and poor
ISPs are being penalized for no fault of them. This is highly
objectionable and discrimination on part of PTA to benefit one set of
licensees at the expense of others.

PTA has also stopped the practice of catching illegal VOIP gateways on
the pretext that once culprits are apprehended, they’re set to walk
free by the high-ups of this country. Instead of catching the real
culprits, PTA has restored to block the information highways of the
country so that no one would have any access to Internet. There cannot
be a more repressive and crude way to implement such rules in the
country.
We therefore request PTA to kindly take immediate corrective measures
on above burning issues and we request for an immediate meeting with
you within this week to resolve these issues.

Kind regards.

Wahaj us Siraj

I am wondering what PTA is going to do when Ipv6 will be under
usage :)
I dont know till when we will be doing things in opposite direction,
from bottom to top. In this case it appears that PTA is testing things
and under implementation phase without generating any policy. I guess
those transport ppl are much influential as they are consulted for any
transport related policy (same is true for fuel companies). Its time
for PTA to understand the market needs and should keep all stake-
holders into loop for any such policy designing.

This is a sensible course of action. I would suggest that ISPs give
their customers a contact number at the PTA and tell them that it is
legal to use Voip unless you terminate traffic to a licenced network.

Lets be very clear. Using PC to PC voip is totally legal and has been
since at least 1996. There is a PTA 'determination' to that effect. So
blocking this kind of traffic is illegal even if it is the PTA doing
it.

I am sure no ISP wants to take the PTA to court but some customer will
do so, if encouraged.

Okay, as I had mentioned yesterday that I would be performing some tests in
my message, I went ahead with it yesterday and did that. There were some
pretty amazing discoveries and hearts broken as well probably the one which
was broken most, was mine. I actually started off with using MSN on one of
the virtual machines and connecting it to another remote peer in the UK and
left both of them listening to music so that packets are coming and going
through. Nothing happened after couple of hours so I had to continue moving
on to the next step.

The next thing that I did was with Yahoo messenger. The exactly same
connected it to a remote peer in UK and let them both sing music to each
other. Continued that for about a couple of hours, although I did not
experience any kind of blockage from my ISP or the demonic authority, I
would like to mention that I am a WiMAX user.
After that I went on to do the same with Skype and it continued for a couple
of hours with same results of no blockage from the ISP or for that matter
TW1.

Now the interesting part as soon as I started transferring or for that
matter originating calls from my PC to a remote asterisk server using
standard session initiation protocol on 5060 the packets were immediately
blocked and I was unable to connect to the asterisk server. So there they
had some success in blocking voice packets. Although I continued to do that
for about an hour’s time but again I did not experience any kind of IP
blockage from my ISP or for that matter the authority.

The next thing was that I quickly build up in asterisk system here at my end
and then from my remote asterisk server I forwarded some calls to my
asterisk server that I had created for experimenting here. I kept on trying
for about 15 minutes and I think approximately after 15 minutes suddenly
everything stopped BOOOMM!! , no browsing, no connectivity to any kind of
outside world and I was unable to even ping my IP address from the outside
world which meant that the IP had been blocked. But to my surprise after
about 40 or 45 minutes everything was again working fine which means that it
was only a temporary block where ever it was.

Although I did not stop there and I started doing the same as soon as I
could connect to Internet and started originating calls from my asterisk in
the UK to my server here. This time it continued for about half an hour and
after that again the IP was blocked although the block this time was not 30
minutes or 40 minutes, it was for a couple of hours. I had presumed that the
Internet connection has been permanently blocked. But it was not the case
and after about a couple of hours I could again continue to browse and work
on Internet as I was doing before.

The next part of the test was to use the VPN server just to see if they
could still detect it and block. I started to use a router and IP sec
tunneling for that. This time it continued for about an hour without any
blockages as such, which made me presume that they are unable to detect any
data that has been encrypted.

Next, was the use of the VPN-based soft phone which would actually connect
directly to an asterisk server at a remote geographical location, using the
VPN tunnel. Again this was successfully done and no blockages were seen in
that.
It makes me wonder whether the amount of money that the authority had
invested last year in getting a solution for themselves, which would
actually be working and not creating a mess in the market like it has done,
was that the right decision or just another aristocratic move that they
love.

God bless Pakistan

P.S someone mentioned one-liners I guess ;) between you and me I guess it
would be okay now.

Thank you very much, for sharing with us the letter that you have written to
the one and only Dr. Yaseen. With all due respects I would like to mention
that everyone in the industry was expecting too much from him than he
actually took the post last year from the general who again in his pedestal
cracked nature only new to run the authority by stick.

I wish he had lived up to expectations and had not fallen for all that
evolves and grows around him.

I would like to mention here that PTA has not stopped catching illegal voice
over IP gateways but you are pretty RIGHT in your message that they are
being freed by the high-ups of the country. Although most of the time the
parties involved agree on a handsome amount of money and things are
forgotten about by the authority.

Sorry for asking about it but are you calling what PTA is doing a sensible
course of action or am I getting it wrong. Let's assume for a minute that
your Internet has been blocked and you have no idea why. What will be the
first thing that you would do? Probably pick up the phone and call your ISPs
helpline and complain that your service is not working.

I'm sure the next thing that they would want you to do is sit in front of
your PC and ping a specific IP or try to ping the DNS servers which would be
working because they are locally located on the same network. The next they
would ask you to probably check out if your DSL modem is synced which it
probably would be and everything would seem to work fine and if they were to
say that probably has something to do with your computer. There you would be
pulling your hair out off your head, but still it would not work. I guess I
event of its out of context here that this is how things work and having a
number for PTA would not help the consumer. Most of the time when a person
is using a dynamic IP TO do is try and reconnect to Internet so that a new
IP address is allotted to them, which would probably solve the issue.

I agree that PC to PC voice over IP is totally legal but at the moment it is
being blocked I should rephrase that it is being actively blocked by PTA. I
know that it is a determination to that effect but who is going to implement
it. About taking PTA to court, it could be a risky business and then the
telecom act protects them as well in this regard.

God bless Pakistan

@ Mr. Bilal. That was one hell of a testing, I guess everyone would
really appreciate your efforts. Just to add little I am using a DSL
connection back home with IP phone. Its running on SIP and since
morning I have made couple of calls and received 4 to 5 calls without
any problem, call duration was more than 15min everytime. I guess PTA
took half day on saturdays :p and turned off Narus (if they r using

So what is the issue here, I might be thick, but could someone explain to me why using voip is a bad thing? As I understand it, bandwidth has a price attached to it, ISP has paid the price to buy that bandwidth. This sounds ludicrous to me if you pay for bandwidth and then can not use it for what you want it for. I can understand if the traffic block was being done for illegal content sharing etc but blocking VOIP is is justified because ....?

I'm most concerned about what implications these actions will have for legit businesses who rely solely on foreign projects and make extensive use of voip, as well as SSL, SSH etc.

Does this mean that one day, I may lose access to all the servers I manage remotely? What happens when I can't show up for a critical Skype meeting because my IP was automatically blocked? Who do I talk to if I become a victim of the aforementioned collateral damage?

No wonder people still think twice before doing business in Pakistan.

I was speaking to a self employed person who is a VOIP professional
and works from home for US/UK clients (like many other now a days). He
is also complaining that currently he cannot work for his clients on
SIP/IAX as most of his servers gets blocked by PTA and he had to buy a
SSL VPN Service just to make sure he is delivering the jobs in time.

I'm not sure if PSEB members are on board, but this should be taken up
with PTA as above example shows that we do have legitimate use of VOIP
in Pakistan other than LDI and Call Centers. Remote Support is a
reality in PK and above actions would be definitely hurting this
portion of our IT industry - though its small and grooming.

Ok the picture I am getting is that, the problem is with PTCL. Haris mentioned illegal LDI operators, problem seems to be the driving force behind LDI operators. What gives them the opportunity to provide undercut rates than PTCL? IMO it is lack of PTCL competency to provide similar or lower rates than these operators. Why does PTCL not try to offer better deals to the masses and let the customers decided which provider to choose for LDI. Why can't PTCL offer similar services to their users which some phat ass can offer by using some cheap equipment?

@ Haris, as I see it, either it is LDI taking the money or PTCL the EU is the only one being conned. And by blocking VOIP the problem is being solved, it is probably making it worst. Why don't PTA not put their weight behind regulations that apply to both LDI and PTCL to provide competative rates to EU and lift the ban on LDI's. There is a massive market which to me it seems PTCL wants to keep hold of by not providing lower rates and not allowing any LDI's ( even if they are legal). It all makes no sense and is hurting the people who pay for the service.

I don't think SSL, SSH, etc. would be affected anytime soon, but just like Wahaj has written a letter, you all too. Every letter sent is something the PTA has to answer to. Create pressure on them.

Both cases were forwarded to PSEB as well but somehow service provider contacted PTA to unblock the IP after resubmission of license copy. Not sure what is the procedure of PSEB for the same and what measures they are taking at this point in time.

Pleasure seeing PSEB participating in this thread.

Can you clarify if there is provision from PSEB for a single professional who wants to use his home PC to provide technical services abroad. Would the same Rs5000 registration fee be required? I presume this would necessitate using a static IP address from the ISP.

Point 2(b) says that "operator has to verify illegal activity". Is there any operator who can verify such thing?

Perhaps we need an RBL type centralized black list server, which PTA can publish and an IP can be checked, if/when/why it was blocked.
I'm sure RoohAfza has that API available. I'm sure TGP can come up with resources to code up a quick and dirty page for this if needed.

One question that begs to be asked is if I as a regular DSL (Home User/Subscriber) decide to use the VoIP functionality in my Wifi Router and get a DID number in the US, and have my family call me - is this considered 'grey traffic' as this surely is no grey-traffic 'gateway'?

I know so many people who use VoIP - and Narus would flag them all - question is - this increase in VoIP dectection - is this all home/user based - has anyone checked to see to whom the IPs are belonging to?

There surely must be illegal SIM gateways, etc. operating here - but for that PTA needs to involve companies that specialize in SIM box detection (which is done by calling into the country, as opposed to sniffing traffic). The determination of what is black (non-kosher) and white (kosher) is becoming grey (no pun intended).

Faisal i think, through regular DSL running the voip in the method
mentioned in your email, falls under grey traffic.
For processing a DSL case, customer signs a bond not to you use any
sort of voice service. Comments from the list will be appreciated.

I think there should be a threshold level and classification of grey traffic should be based on sampling at different intervals- occassional use with less than 100k of voip traffic should not fall under this category - If a flag is raised for a perticular IP then it should be sampled at different intervals and after that ISPs should be informed to take action in this regard -

I would second the comments of Mr. Faez that there should be sampling. Combating "gray traffic" means catching those so called companies who are providing illegal ILD/DLD and for sure they generate continuous voice traffic.
 
If PTA is going to block the users like Faisal than they won't get much revenue out of it because the gray traffic is originating from high tech systems and seriously I haven't heard any major break through from this blocking till todate rather than frustrated home and corporate users. Simple way to avoid this is, you create a tunnel and bingo. Now it opens up another window of opportunity for gray traffic, start selling VPN boxes for voice traffic :) I guess its already available but right time to market it again.

The contract is a cop out by the ISP. There is no law or regulation

The idea behind all this is not ONLY to handle gray traffic, if it’s so few or at least one of among those who are generating illegal traffic must have arrested rather just to block them (Illegal generation of VoIP traffic can lead to arrest under PTA’s law). It doesn’t make any sense to block all internet traffic over the IP even if it could be blocked for specific protocols.

Recently I had a meeting with one of PTCL higher official, they have clear set of mind for DSL service providers to come with PTCL or prepare to war against their survival (good opportunity for those ISP’s who have only DSL service), as i know one has accepted. They are in a way to reduce their competitors in consumer market. Can any one make sure if the same thing happening on PTCL DSL service, because when I called to PTCL support center they were not reported yet for any such complain.

They are just trying to irritate SME’s and home users as we aware that normally home users take broadband services to gain better voice/video quality on Yahoo webcam or any messenger to be in touch with their relatives live abroad. It sounds good PTCL finally aggressive to botch DSL market but PTA shouldn’t be the part of any unfair game

PTCL/PTA, etc. should use these companies who specialize in VoIP / SIM Box detection rather than just blatantly blocking IPs:


http://www.meucci-solutions.com
http://www.revector.com
http://www.araxxe.com
http://www.xintec.com
http://www.agilisinternational.com

Sim Box detection is useless, When one of the SIM will block. Grey operator can use another SIM for calls.

I think, get a new SIM is more easily then to get a new IP even after the implementation of 789 for the SIM activation.

Very well said Ashar, I agree with you that there is no law currently which
defines whether voice over IP is illegal or legal. There is that old
telegraph act which they have always made a base for their cases.

Any news from PTA on this. We were blocked today although we have a
firewall that blocks ports and allows legitimate ones only. We are a
corporate office and nobody uses any VOIP termination here, still we
got blocked. I don't know what sort of classification PTA is using to
define grey traffic. I fear if they are blocking legitimate users. :(

No News as of yet I guess, No one has received any updates ! I think
if you can explain your situation in a bit more detail than I think I
might be able to help you out in getting your IPs reopened. Please be
as descriptive as you can ! I had mentioned earlier that they do block
you if you use SIP on the default ports !

I agree, There are serious issues with PTA IP blocking, I have faced it couple of times.
They block our firewall IP even when there is no VoIP traffic (VoIP traffic is already blocked from inside to outside by firewall).
 
Any one from PTA on this forum kindly explain the criteria of blocking.

We block all ports except the ones given below. I don't think any of
them is used by default SIP or H323.

1-110 tcp/udp
443 tcp
8443 tcp
2095 tcp
2096 tcp
995 tcp
11371 tcp
143 tcp
1863 tcp/udp
5222 tcp/udp
5223 tcp/udp
2082 tcp
2083 tcp
2088 tcp

NEXLINX is our Internet Service Provider. IP blocked is 202.59.70.115

@Khalid, TCP 443 is used by Skype.
 
Something is seriouly wrong today with PTA and their roohafza, we have bombarded with IP block queries and to make things really nice PTA is sleeping and haven't responded to any of our query.
 
I seriously doubt the role of ISPAK atleast for this case. Pardon me if I'm wrong but I don't see any development.

A bit off-thread (but definitely not off-topic): ISPAK - or anything similar - is badly needed today for fixing the current content-meddling activities of PTA. 

Unfortunately, with the demise of conventional ISPs and the rise of voice-driven telcos as the new-age ISPs, somewhere in between, we left out the platform that could address 'Internet industry issues' as its prime focus. 

Today, we have functional LDI industry groups (and the celluar voice probably doesn't need any grouping as there are too few players to have communication problems) but we are short of an Internet industry group. 

The ISPAK of yesteryears first rose from Karachi with Cybernet a major financial and moral driver and active participation from others and a parallel version blossomed in North and both delivered tremendous value and achieved major milestones. The Internet user had a very distinct voice in the name of this (these?) bodies. However, today the platform probably lacks the participation, the passion and the investment that it deserves (barring a few souls that had been delivering consistently without any break such as Wahaj sb et al). 

As Internet and broadband penetration increases in Pakistan in the coming days (hopefully!), we will move from a connectivity hunger to full-functionality hunger. And the issues will get more complex. The only way of addressing this is to encourage and urge the players to invest time and money in an industry platform that can potentially address these challenges lurking around the corner. I make a passionate appeal to all who have anything to do Internet to come forward and increase their participation in ISPAK and make it the voice of the ordinary Internet user.

Dear Adeel and others,

I have been watching this tread going a LONG way and wanted to add very small note here.

I have NOT read the whole thread as there are TOO many emails on here, but here are my 2
cents.


The site internetcalls.net software uses vpn already and it is not going to get blocked if u use
that.

Same for voipbuster.com and other 50 other sites from that same company will not be
blocked due to Naurus.

Google talk is also something that still works fine even in uae, and can not be blocked by
naurus.

All these product work fine in UAE also where almost nothing works.

Well IAX2 also works.

Till now naurus only blocks SIP Calls in uae and also some times SKYPE does not work ,
even for chat it does not work some times, but in Pakistan I think that Naurus is not yet in full
effect.

and it is NOT in my opinion going to do ANYTHING for illegal voip operation, illegal voip
providers will keep on terminating illegal traffic via gazillion other ways, like gaisal mentioned
vpn is one of them.

These disruptive technologies are NOT stopable, and the only people they will stop are the
people that are innocent end internet users, and NO ONE else.

PLEASE this country is already going though a LOT of other mess, please DO NOT mess up
this small beautiful thing called the internet for us, as this is the ONLY way we MAY be able
to survive in this new world.

I Encourage all of you, to start sending fax and letters to

1. PSEB MD
2. PTA Chairman
3. Ministry of IT

Asking them to OPEN UP Voip in Pakistan and take way the LABEL of ILLEGAL from it, as
People like Faisal Chohan are people who make money and reputation for this country and
are not some one you want to loose from this nation, DO NOT scare people like him away
from this country PLEASE.

I am not a lawyer, but having been at the receiving end of PTCLs
attentions while engaged in the VOIP business I have read some of the
relevant laws. There is no law against VOIP. PC to PC Voip (or to be
correct: device to device Voip) is entirely legal except that as soon
as you connect a licenced network to an unlicenced network you are in
trouble.

Just read the Pakistan Telecommunication (Re-organisation) Act, 1996
(there are several copies out there
http://www.google.com.pk/search?q=pakistan+telcommunication+reorganisation+ordinance&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
)

Read all of it but especially section 20 and it should be fairly clear.

Lets be clear: if there is no law that defines an act as illegal then
that act is legal. We do not need permission from the govt for
anything.

I am copying a relevant section from PTA web site here, this might be helpful:

http://www.pta.gov.pk/index.php?option=com_content&task=view&id=668&scid=150&Itemid=1

..................
Since its inception, PTA has always been there for growth of telecom business and ICT in the country. It is particularly concerned about that VoIP which is being used by some illegal operators for illegitimate termination / origination of international traffic involving use of VoIP on commercial scale by setting up of gateways and mini exchanges without a valid license. It is not in the knowledge of general public if; PTA ever has restricted VoIP for individuals using different programs to chat with their loved ones with a personal computer on both ends. The students and researchers are using it for interacting with each other regarding their research purposes without any barriers. Last but not the least, business community all over Pakistan uses it in order to fulfill their communication needs. Legality of VoIP comes into question only when some one exploits its benefits for illegal commercial purposes. PTA?s stance appears to be based on fairness and its determination to eliminate grey market telephony needs to be supported by all players.

The law also says that IF the voip is done by an end user, using the LDI provided internet
allowed for voice traffic, it is 100% legal.

The law is so confusing, that it needs to be cleared out in black and white.

Sorry Rehan, the Law does not say that. That is just an interpretation
- and it makes absolutely no sense at all if you read the Law.

it is not just LAW but the interpretation of it, the point is how much
justified it i ?
long ago PTA released a "VOIP SERVICES" Public information
Bulletin .......which says; (in 2nd paragraph)


"Under the present technology neutral licensing regime, VoIP services
can be provided by Local Loop (LL), Long Distance International (LDI)
and Cellular mobile Operators licensed by PTA. It may also be
clarified that IP bandwidth provided by ISPs / DSL operators is for
"data" only and it cannot be used for "voice" i.e making calls."

the funny part is they are separating VOICE from DATA whereas voice =
data (technically speaking).

conclusion: PTA says VOIP is such a good thing but you don't deserve
to use because you are underprivileged one :)

Well that is my interpretetion of the paper from PTA, and that is why I think that PTA should
use a clearer language, and go ahead with that ad for telling the masses that they are not
breaking the law.

Even I think that PASHA can also put that ad in the paper, if that is what pasha thinks is the
meaning.

Dear All,

Sources from different ISPs have confirm that PTA is Blocking client
IPs now in full swing where as demanding other personal information of
client in detail. Please confirm if yo have any written source from
PTA side. Also confirm if the same demand from PTA is entertained from
all ISPs as my IP is also blocked due to only use of MSN & Yahoo
Messenger.

I am not much of a telecom expert, but would like to know of any views and possible reasons as to why PTCL may have started blocking SSL ports.

Does it make any sense?

Would appreciate some opinions.

Thanks,

PTA is now really messing up with the user traffic big time. A large
number of IP addresses of end customers were blocked in the past few
days and most of them were end PC-to-PC voip cases.

The Naurus trigger happy team is probably trying to justify their
existence and what was being predicted at the time when this facility
was being set up is happening now.

PTA has started this activity aggressively from 25th Feb and due to this customers are suffering. There is no logic behind this they just want to block VOIP and for that they are blocking IPs without any investigations.

But if Naurus is any bit intelligent, it should be able to distinguish between the occasional MSN/Yahoo/Google voice chat user and the bulk grey market operator.

Or am i expecting too much common sense and intelligence from PTCL?

People of the group hello,

Blocking the IP goes back to mid-of Ramadan when they actually started
blocking of IP addresses of people who were involved in either
termination\origination of gray telephony, or were just ordinary users of
voice over IP, which included users of Yahoo messenger, MSN messenger and
other similar applications. I am aware that Skype as of yet has managed to
escape the eyes of a authority.

Referring to a blog post by TM where it is referred to as a more evil stance
by LDI operators, I agree that it has actually now being developed into a
full-fledged evil. Although keeping things balanced in this conversation I
would like to mention that people whose IP addresses have been blocked are
the ones using static IP facilities from their ISP. The point that the
authority makes here is that not every ordinary ISP user requires a static
IP address which is a fair argument on their end, and they are only
requesting the ISPs to block the static IP's.

I am not a supporter of the authority in any way and I personally disagree
with what they have been doing and condemn it in the strongest possible
words. I consider this to be an invasion of privacy on till they have the
proof that one of the of IPs that they have blocked is being used for
mala-fide intentions or being used for grey telephony. There have been
victims of the authority all around the country there they have raided
offices and have unsuccessfully done anything except for bringing a bad name
to the person or the company which were raided by them.

Coming back to the main issue of blocking the IP address as I said that
started in mid of Ramadan and then it was basically stopped for a few months
now I am hearing again that because there has been an increase in grey
telephony because of the increase in APC and rates for incoming traffic in
Pakistan, those who were in this business have started offering the services
again. Video techniques have now been employed by people who are doing this
like using VPN servers and SSL ports which the authority is unable to
monitor as of yet. Therefore they have no other option but to block ports
which they fear are being used for illegal telephony.

God bless Pakistan

PTA has acquired complete cliental /IP allocation details from all
ISPs few months back and now they have started this blocking. If its a
PTA policy then it should be publicize properly (like SIM registration
compaign) to all whole internet user community so that everyone should
now about it. Its quite difficult from ISPs point of view to educate
all its customers about this new change.
I have serious concerns about such PTA step but even if its IN-
EVITABLE than it should be properly publicized and prior to
blocking........ a notice should be issued to conerns accordingly (to
avoid any SURPRISE AT THE ELEVENTH HOUR)

But Actual Issue which i am facing to secure my IP Address which i
have install on my server ( The aggregation Point ) and after blocking
my IP, my Browsing was also stopped. I am totally amazed on this
situation and i am trying to terminate the link as this IP is totally
useless for me.

I am also thinking to switch on another ISP Connection with additional
IP Pool. For my previous IP which is Block from PTA, may be that ISP
can negotiate with PTA to release that IP as maybe this IP is also
useless for them and they will inform to PTA about my termination as
well.

I think PTCL is giving Dynamic IP and clients can use VOIP on Dynamic
IP as package would be less expensive and without and limitation as as
soon as i will disconnect, my new IP would be automatically assign to
me.

Muhammad Anees Ur Rahman

Hello, I agree that it is happening on dynamic IP's as well but this is not
what PTA is saying they just tend to put it as they have only blocked static
IPs which were being used for voice over IP. Now I think that it would be
unjust to say that they are not blocking dynamic IPs which I am aware that
they are. I appreciate you adding this comment.

Although voice over IP is such a broad field that you can't just block
everything that is voice and you should not actually block everything which
is voice because at least I consider this to be pretty discriminatory, why
not just block Internet all along. This is a total different debate though.

Also for the benefit of this post I will be using Yahoo messenger , MSN
messenger etc. etc. For voice all day today, just to see if they are going
to block me or not. I would also be originating some calls using Yahoo
messenger Skype and other facilities that I have available to me, just to
see if they block me or not. I will definitely be posting the results if I
do get blocked, I will be using wire shark to monitor all the packets and
will be posting a link where I will have all of my logs posted.

God bless Pakistan

Concur. Inside sources at 3 different ISPs confirm that automated blocking of dynamic IPs is occurring. For the last few days, using WorldCALL has become nigh impossible (though, that may be because of their internal technical issues as well).

Blocking SSL is just plain inane. Can someone get the Authority to comment on this? Whats next, blocking SSH?

Dr Sb, we though perhaps PTA would become a little less autocratic and militant in its policing of the country's Internet under your tenure.
Sadly, this doesn't seem to be the case.

just to add to it - Narus has been experiencing a few problems within PTA. Narus is not able to extract Calling Party A/B number. PTCL recently put out an RFP for just this, procurement of a solution that enables DPI and extraction of A/B numbers, so that the dynamic IPs do not suffer. However, since this was just tendered, it will be months before the solution is actually implemented (provided PTCL buys it).

Any IP that PTA detects using VoIP is automatically blocked. PTCL and TWA for that matter both have been active in blocking such IPs, which in most cases are dynamic IPs and that the next user in line to get this dynamically (blocked) IP assigned, wonders what the heck is wrong with his/her internet connection.

Its a plain mess if you ask me.

The first case of IP Block due to voice traffic was reported in August but somehow it was for a week or so and than everything went back to normal. All of a sudden someone woke up in PTA and decided to do the same in December but at that time only TW was properly intimating their customers for every IP they were blocking on request of PTA. Again it was just for few days.
 
But as someone stated that IP blocking is getting worse for last couple of weeks. The most important thing is that Service Provider doesn't even know if their IP is blocked. As per upstream providers they can't intimate all their customers due to frequency of IP blocking request.
 
So its a complete mess and to unblock that IP you need to submit an apology letter or some sort of undertaking from customer that such voice activity will not be performed in future.
 
I don't think that this is the issue of Narus efficiency, the problem is because of vague policy. I have just heard that PTA will circulate some sort of guidelines to all service provider regarding some update in their policy and recent ip blocking issue. How amazing? :) Shouldn't it be done before creating the mess.
If you request PTA to provide the logs, they will say we don't have it :) if you say that we have already submitted the call center license copy for this customer, they will just say opps "your IP has been accommodated"
 
is it something wrong with the policy or with the implementation?

I believe all these activities are happening on adhoc basis and seems all R&D is  being done at the cost of live networks- we have been seeing and experiencing all such so called 'illegal VoIP' blocking activities from past many years and this recent activity shows we have not learned much from the past - Those who are in this  'illegal' business i think have learned many other ways to bypass such controls and the ones who are being affected are normal ISP/internet customers
 
On one hand efforts are being done to promote broadband/internet penetration while on the other such activities are hampering the overall industry- 
 
I wonder if anyone knows exactly what is allowed and what is not and that's why we are still unable to define exact control policies at egress points-

@ Mr Anees. if your IP is getting blocked at one ISP than the chances are very high that it will be blocked at other ISP as well. So why taking the hassle of changing the provider rather take up the case with your current ISP. Every ISP is bugging PTA on daily basis. Problem is there is only 1 land line number and email response is at times very slow.
 
@ Mr. Bilal. Its quite amazing to know that PTA said that they are only blocking static IPs. How on earth they know that its a static IP or dynamic one :) they are just doing it for the sake of it. Your test would really help many on the list, nice initiative.
 
Will be waiting for it and how about submitting a report at the end of the day to PTA as well :) because for sure they haven't done any test run like that prior to implementing this policy.

Bilal the system implemented at egress does know if its a dynamic ip
or static IP.

I don't think (as faisal khan has mentioned) that naurus cant block
skype/yahoo/msn type of voice communication - as identification of
traffic is happening on port basis, not via DPI

Right faisal ?
