[OpenSIPS-Users] B2BUA Implementation for Transfer

Sat Oct 30 20:22:19 CEST 2010

OK.  So maybe the opensips core dumps were because I was calling the B2B_init
before I was calling my Nat_Traversal Route.  I placed my B2B_INIT after
doing NAT traversal and call transfers work almost ok.  I have a internal
user call a PSTN number, the call connects and then I transfer the PSTN call
to another internal user.  The call is transfered but the internal user that
gets the transfer gets a Caller ID of UNAVAILABLE.  The UNAVAILABLE is
coming from the PSTN SIP provider, so I am not sure if there is anything I
can do about that.

Here is my SIP trace of the call in action.  I also have a lot of NOTIFY
messages that appear to not get  any responses.  Am I doing this right
because non of my SIP Messages in this trace have a CALL-ID starting with
B2Bxxxxxxxxxxxxx.
