Hi Ben, I managed to lay my hand on the device I was using back in February and everything works (except the fact of delay, and echo which I believe is solvable by playing with the PJMEDIA_SOUND_BUFFER_COUNT, PTIME and others). Just in case anyone is facing the same symptom, the device I have had experienced the problem is a brand new HTC model p3600i.
