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@domain").
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
