I want to share my thoughts related to VOIP/illegal VOIP or rates
changes
There are several views about rate changes of VOIP calls during last
year
1- One point is that industry needs money, its about macro economy
bcoz we all know about the situation of LDIs before rate change.
2- One view is related to individual who has to pay for the calls.
3- Another point is related to the progress in order to augment the
end user's comfort for example if we compare rates of calls to India &
Pakistan (similar to the second point)
Now for illegal VOIP, as we all know most of the or all the illegal
VOIP GWs use GSM SIMs or sometimes E1s for terminating their calls,
and PTA normally gets the information about the SIMs used by those GWs
but unfortunately the numbers ( or the SIMs) are not registered to
original user bla bla.... We have already seen in past that PTA took
some steps in order to block these type of SIMs but unfortunately our
authority (PTA) could not find a proper solution or could not
implement the proper solution.... bcoz to me if the SIMs are issued
with proper record then it will be easy to locate the illegal GW or
the person using that GW...... When I hear the add from PTA on radio
like " it is illegal to use the SIM which is not registered to you"
then I start thinking what is the use of playing this, you have the
resources/authority to block these SIMs go and do that instead you are
playing the message on radio and that is listened by the nation having
such literacy rate that many of them don't know what is the meaning of
this......
Secondly, to my knowledge PTA has invested a lot for blocking/
detecting illegal VOIP on international links but still asking the
ISPs to block that. As we all know most of the times ISPs don't have
proper equipment to block VOIP, normally port blocking at transport
layer using ACLs etc. and we all know that will not work in case of
illegal VOIP players unless you go to layers above transport layer.
There are various tunneling methods as well as VPN solutions available
for hiding the data so practically most of the ISPs don't have such
facility or can't bear such load on normal devices.
I was going through a document from PTA mentioning something like "VPN/
Encryption is not allowed on DSL ....." , I am not sure about the
thoughts of policy makers but I think that was for illegal VOIP so,
why not we remove VOIP from our courses or VOIP study only allowed for
a limited group :)
For Telecommunication's Big Brother!!
I think PTA/We want to keep our self limited to a certain level.....
Problems will not be solved unless we increase our knowledge/skills
instead of only relying on the equipment like Naurus.
Regards,
and at the same time blocking illegal VOIP
