calls are disconnected after 90 s

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello ,


Bingo.It works....thank you Bernard Poquillon.

I have made a rapid hack in \pjspi\src\sip_dialog.c and it works.

But i have another question for python programmers using pjsua:

Can i do the same thing in my python code?

Is there a callback function to receive INFO request and send the 
response?


Thank you.

F?lix.

Hi,
 
After registration is done, pjsip sends an INVITE which is accepted. Then 
every 30 seconds, the server sends a INFO which pjsip answers to with 500 
(unhandled). After the third answer, the server disconnects the call.
Some PBX like sending INFO packets; it is like a heartbeat. I saw that on 
Cisco but Cisco accepts an answer with 500. It seems that your PBX 
doesn?t. You should modify your code to respond with 200 OK to INFO. Or 
look at the configuration of your PBX, perhaps it is possible to use 
session timers (RFC 4028) instead of INFO for call supervision.
 
Regards
Poq

Objet : [pjsip] calls are disconnected after 90 s
 
Hello, 


I have  compiled with success all the projects related to pjsip with 
Visual sutio express( 12 ) and the target is for win7. 
I have tried to make an outgoing call or a ingoing call using  the sample 
call.py in python and also using the test pjsua console program. 
I call from the win7 PC to an aastra IPPHONE via an aastra ACS5000 voip 
Pbx or from the aastra IPPHONE to the PC. 
The call is established but after 90 s,the call is disconnected. 
I have made the same tests with linphone and xlite...it works. 
I have made the test with microsip....the calls are disconnected after 
90s...so my conclusion is there is a problem of compatibility between my 
aastra Pbx and pjsip...but how to track this? 
I would appreciate some help or an idea on how to track the problem. 

below the wireshark sip/sdp capture for an outgoing call. 


Thank you for your help. 

F?lix.
