If so, reliable provisional response should solve it I think. You can require remote to send response reliably with --use-100rel option in pjsua. If you think that listening for incoming RTP is the only way to go, then for now the only way is to hack the UDP media transport to call your callback whenever there's an incoming RTP packet. Or something like that, I haven't thought of this very thoroughly. In the future I'm planning to add another callback in pjsua-lib to allow application to create its own media transport (or to report media transport creation). This among other thing will enable application such as yours to do some work with the transport. cheers, -benny > Davide
