Re: [OpenSER-Users] call forking

Bernard,

Your config looks ok to me. Something rather weird must happen with the call signaling if users C and D receive the calls 15 secs after dialing user B. A tcpdump trace would help to debug this problem. Can you run

% tcpdump -i any -s 1500 -w /tmp/sip.pcap

on the proxy host and post the sip.pcap file.

Hi

I'm trying to do some call forking but I can't manage to make it work well. I explain quickly what it is : If user A call user B and user B is registered more than once (on different system), the proxy will fork natively to all registered user B.

What I want to do now is if user A call user B then the proxy fork to user C, user D and so on. I have found the command append_branch("sip:userC at domain http://openser.org/cgi-bin/mailman/listinfo/users").

The thing is that it is not working well. For the first time (when the server restart), I make a call from user A, only user B receive the call, then ignored the call from the user B and wait for about 15sec then the call ring on user C and D. I make the 2nd try, user A call B, B, C & D receive the ring. Then I wait some minute, the problem came back again

what is wrong with the first call, a bug or configuration error ?

please help Bernard
