Changing RTP audio port at SIP side and notifying H323endpoint
Posted: Thu Apr 13, 2017 5:05 pm
Hi, I am developping a SIP <=> H323 gateway.
My test scenario has one cisco device talking H323 and another one talking SIP.
At some point, I put the call on hold, and when I resume the call, I need to create a new RTP audio port for the H323endpoint, so it can send its audio data.
I wrote the code to create that port and send an open logical channel notifying the H323 endpoint to use it. But it seems the H323endpoint keeps sending audio to the old RTP port, it ignores my "Open Logical channel" msg with the new port.
Does anybody know how could I make the H323endpoint send data to the new audio port?
