even i tried manually copying library files from mobicents-ss7-service/lib, but still the error is there.

Regards.

[yulian_o]

Under bin folder of shell create lib folder.
Put in it http://download.java.net/maven/2/javolution/javolution/5.5.1/javolution-5.5.1.jar
run the ss7-run.sh once again.

Actually there is no bin folder in shell directory, i created bin directory inside that i created lib and then download the  javolution-5.5.1.jar as you suggested. still the error is same. 

[yulian_o]

Hello
There is bin folder see CLASSPATH: /usr/src/mobicents/ss7/mobicents-sgw/bin/mobicents-ss7-shell.jar

that means that mobicents-ss7-shell.jar is in bin folder.under this folder create lib folder and but javolution jar into it

Best regards
Yulian

[Gopal]

May be dahdi has to be installed? or dahdi hardware to be present? 

Regards, 

[Gopal]

Yes after copying to the proper lib folder now i get the mobicents> CLI prompt, from there if i type ss7 connect its giving connection refused. 

I have started the ss7 simulator and it is waiting for the commands. I tried both the simulator and signal gateway as a service. in both I am resulted to connection refused. 

Regards,

[Gopal]

let me check

[Gopal]

yes now i am able to see the linkset status. thank you very much. 

[Gopal]

so now for dial plans i understand that i have to use asterisk. But how about dahdi, that will be integrated with jndi? or i have to install dahdi seperately? 

Regards

[yulian_o]

Hello
what is exactly your goal?

Best regards
Yulian Oifa

[Gopal]

I have a PRI card, I want to test with mobicents SS7. by dialing some calls via SS7 link. 

Regards

[yulian_o]

Hello
On sgw side you should install dahdi
Best regards
Yulian Oifa

[Gopal]

Do I need maven for this? or any binary version is there which can be used?

Regards.

[Gopal]

actually what i had is mobicents-jss7 2.0.0 beta, as we discussed earlier, i started run.sh in mobicents-sgw and from the shell i started ss7-run.sh. Following are the steps,

mobicents>ss7 connect 127.0.0.1 3436

mobicents(127.0.0.1:3436)>linkset create dahdi opc 1 apc 2 ni 0 allosupport

LinkSet successfully added

mobicents(127.0.0.1:3436)>linkset activate allosupport

java.lang.Exception: No Links for this LinkSet are configured

mobicents(127.0.0.1:3436)>linkset link create span 1 code 1 channel 1 allosupport link1

Link successfully added

mobicents(127.0.0.1:3436)>linkset activate allosupport

java.lang.Exception: No Links for this LinkSet are configured

mobicents(127.0.0.1:3436)>linkset link activate allosupport link1

mobicents(127.0.0.1:3436)>

in the above steps while activating the linkset link i am getting the error. 

FYI: I have installed dahdi 2.5.0 driver and I have two port PRI card, where i connected loopback and the link is UP in Asterisk console. 

PRI span 1/0: Provisioned, Up, Active

PRI span 2/0: Provisioned, Up, Active

I hope the error is something related to /usr/src/mobicents/ss7/mobicents-sgw/native/libmobicents-dahdi-linux.so, basically what is the dahdi version compiled with the so file?

Regards,

Gopal. 

[yulian_o]

Hello
It looks like mobicents dahdi you are having is not compiled on same architechture you are using.
Please compile ss7 source with -Pdahdilinux on your server and use libmobicents-dahdi-linux.so from your local compiled copy

Best regards
Yulian Oifa

[yulian_o]

Hello
You can also check your java version.

[Gopal]

just now i found so far i am using binary version, just downloaded src verison and doing mvn  clean install -Pdahdilinux, lets see what happens, its taking more time to download from repo... anyways i will wait for the progress. 

Thanks & Regards,

Gopal

[Gopal]

After doing "mvn clean install -Pdahdilinux" from the ss7 source, its struck here,

[Gopal]

Actually finally my BUILD was successful. And copied libmobicents-dahdi-linux.so to the binary version's folder and i am able to start the run.sh under mobicents-sgw gateway folder. Actually from the source i am not able to run the sh run.sh, after copying to the binary version;s folder i am able to run. that's fine. 

Now I have one PRI card, just connected loopback from span 1 to span 2. and started sh run.sh and connected the client through ss7 connect also created linkset as given in the pdf file.

I receive some comments like the below, and tried to run "linkset show"

I hope this is line error. am i correct, please correct me if i am wrong. 

Regards. 

[yulian_o]

Hello
1) What is your system.conf dahdi configuration , bchan should be configured on all channels in span 1 and 2 , also set correct timer on both spans ( if you set timer on one , it should be disabled on second ).
2) you are using same span and channel on both linksets , change one of them to span 2.same with opc and apc.
You should receive something like this in the end :

allosupport    dahdi    opc=1           apc=2           ni=0    state=UNAVAILABLE

    link1       span=1   channelId=1   code=1  state=UNAVAILABLE

linkset1      dahdi    opc=2           apc=1           ni=0    state=UNAVAILABLE

    link1       span=2   channelId=1   code=1  state=UNAVAILABLE

Best regards
Yulian Oifa

[Gopal]

actually my system.conf is proper. in asterisk pri show span is showing UP and Active. Actually i created one linkset and link yesterday and today with same parameter. that's why it shows one as allosupport and another linkset1 with same values, i have removed one. 

Now its showing only one,

Receive linkset show

linkset1      dahdi    opc=1           apc=2           ni=0    state=UNAVAILABLE

    link1       span=1   channelId=1   code=1  state=UNAVAILABLE

Since I have connected loopback the link won't come UP. I am thinking to setup libss7 trunking between two PC's will that help me to check the link state as AVAILABLE! 

 

Regards. 

[Gopal]

I think i can use SS7 simulator. will that work for me?

Regards, 

[yulian_o]

Why dont you just create 2 linksets and one link in each,
One link on span 1 and one link on span 2 , so they will talk each other?

I am not familiar with ss7 simulator so can not tell you what it does.

Best regards
Yulian Oifa

[Gopal]

ok let me try and with ss7 simulator there is no support for dahdi as of now. 

Regards, 

[Gopal]

i have created like this,

mobicents(127.0.0.1:3436)>linkset show

linkset1      dahdi    opc=1           apc=2           ni=0    state=UNAVAILABLE

    link1       span=1   channelId=1   code=1  state=UNAVAILABLE

linkset2      dahdi    opc=2           apc=1           ni=0    state=UNAVAILABLE

    link2       span=2   channelId=1   code=1  state=UNAVAILABLE

and loopback is connected from span 1 to span 2, but still the stat is UNAVAILABLE. 

Regards,

[yulian_o]

Hello
please provide a sgw log , and dahd system.conf

Best regards
Yulian Oifa

[Gopal]

Find the attached.

[yulian_o]

Hello
1) On span 2 ,  3 , 4 disable timing source
2) I dont see that you have activated link 2 and linkset 2 , since only link1 is trying to sync. so activate them.

Best regards
Yulian Oifa

[Gopal]

I have disabled the timing source for 3 and 4 by changing the value to 0. 

Now there is no error messages in the sgw log,

run activate on linksets and links , they are curently not trying to sync.

I have activated the linkset and link like the below as mentioned in the pdf file,

[Gopal]

Hi,

Finally the loopback test is fine, I dont know what happen, suddenly the link came up and the state is AVAILABLE. :D Many thanks. 

Now what I have just did one more setup. In one PC I have Asterisk with ChanSS7 and in another I have the same Mobicents setup (existing one), in chanss7 the setup is configured in ss7.conf and the same linkset and link name i have created in Mobicents-SS7 machine with different opc and apc value, as did in loopback. 

But the link is not coming UP. 

Regards,

[yulian_o]

Hello
I would recommend you to use libss7 instead of chanss7
You should set mtp2=x , where x is channel id of connected link.
Check clock settings since its important also.

Best regards
Yulian Oifa

[Victor Neiman]

Hi Gopal,

I have a similar problem to yours where I have an Asterisk box and a Mobicents SGW box and a Sangoma E1 card in each. The problem is that Mobicents SGW keeps logging

15:27:50,193 INFO  [link1-1] (link1-1) Restarting initial alignment
15:27:50,194 DEBUG [link1-1] (link1-1) Starting initial alignment
15:27:50,194 INFO  [link1-1] State changed in link. OUT_OF_SERVICE --> NOT_ALIGNED

Whilst the Asterisk box keeps logging:

[Sep 28 17:34:29] NOTICE[20242]: chan_dahdi.c:3437 my_handle_link_exception: SS7 got event: HDLC Abort(6) on span 1/0

If I stop SGW then the errors on the Asterisk side stop. I would like to know if you found a resolution to your problem?

Regards and thanks
Victor

[Manish Goyal]

Hi,

My reply is probably too late, but I am trying to build a 64 bit Linux native library but I am not able to compile the src. I have tried 2.1.0-FINAL and couple of others.

I have spent many hours trying to resolve Maven issues, but I think they keep coming in. I need help with building the native binary for 64bit linux (CentOS). Or, If anyone has the binary created for 2.0.0-BETA can you please share?

Thanks,
Manish
