Hello,

the log errors don't seem related to rtp proxying.

Can you paste here what you have in kamailio.cfg at line 943?

The other error in syslog is related to a duplicate key, most probably in cdrs table or some other table you populate with sql_query() from kamailio.cfg -- the conflict is on unique key 'uk_cft'.

In both traces, labeled working or not working, there is no rtpproxy invoked for signaling, thus no rtp relaying done by sip server. The rtp stream should go directly from caller to callee. The ip addresses suggest that caller and callee are both in the same local network as sip server. So, unless there are some firewalls around, all should just go fine. Or maybe there are some bugs in the softphone. Kamailio is not involved in rtp at all.

Cheers,
Daniel

Dear All,

I am running a kamailio 4.0.3 server, it was working fine with the features like- audio calling, video calling , SMS (but presence is not working). But from last two days I’m facing problems with RTP packets streaming between SIP clients (IMSDroid clients). Session establishment between two clients works well but without audio and video streaming. And after sometime again it works well. What is this wierd behaviour?

Following attachments are Audio calling cases of working and not working (ngrep based), And i have found some errors in Syslog (attached) and my config file for any reference.    

What could be the problem? How can i solve the issue?

Anybody please help me.

Regards,
