hello FreeSWITCH community, actually it is my first time to use lists like this. I hope I do everything fine. For my project I try to get stereo (and some special features later) integrated in freeSWITCH, especially SIP. TO start with this idea I need to know where I have to activate or implement stereo. In the second I try to play a bit with the portaudio module as I do not have to focus on SDP problems transporting SIP and the need of a SIP client which is able to receive stereo. So I set up some custom moh local media stuff which works finde - using mono. Changing the channels to 2 makes the console telling me that the sound file will be mixed to mono and the sound is quite strange. I would be happy about getting some useful information which modules or configs are the important ones for my idea. Unfurtun ately I have only found some recording stuff about stereo which is not what I want to do. Thank you very much. MatzeMuc86
