My problem was no voice was transmitted during a phone call that's why I can't hear the voice of the person on the other network. I think someone had faced this problem before here is the link.. http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-June/003452.html Im sorry but i dont have any idea on how to transmit voice. This is what I did. Call the pjsua_call_make_call function to begin the invite Sip Call Then on the other end, call the function pjsua_call_answer then the call is successfully established but no audio is enable. How can I enable the audio during the call? this is what I wanted to know.. Hope you can help me guys, a sample code on how to make it will be very useful.. Thanks in advance..

How come? ?With Audio Proxy Server the Audio priorities it's automatically managed by Symbian . I think it's still way too early to conclude that this is a priority issue. There are many other reasons that could cause the loss of audio (please see the audio troubleshooting link). Cheers ?Benny ?
