Thanks Benny. Just so I'm clear.. should I expect no audio? I ask because I tested on two P1i's. The application runs fine. Registration is smooth and the call is successful.. it's just that there is no sound. Is this the expected behavior or should there be some semblance of audio? ________________________________________ Samer M.
