Hi,I'm going thru the sipecho.c source code and it is not clear to me how it echoes RTP back to the UAC.I can see it copies the offer SDP, removes some attributes, leaves a single codec and replies but I don't see where it handles the incoming RTP packets.
Ah, I got it.
Actually sipecho doesn't handle media at all: it just replies with an answer-SDP where the RTP endpoint in the same as in the offer-SDP.
So the uac sends RTP to its own RTP endpoint.
