Hi folks I've managed to build pjsip for symbian (based on snd_has_MDA) and was just wondering if anyone could help me to determine that the echo suppressor is being used. That is, where and how do I check to make sure the echo suppressor is kicking in and being utilized. Also, how do I reduce and increase the sound volume.
