OK Let me rephrase my previous question. I was able to use TCP for SIP signaling by simply setting #define PJ_HAS_TCP 1 in config_site.h and creating a TCP transport instead of a UDP transport in the main of pjsua_wince.cpp However, while running Wireshark I realize that the audio streaming is still RTP over UDP. My question is still the same. Is it possible to transport the entire audio stream over TCP, i.e. RTP over TCP, and not just the SIP signaling? Thanks again. ________________________________________ Samer M. Faour Computer and Communications Engineering American University of Beirut P.O.
