Hi I'm trying to set up audio conferences with mod_conference. Functionality works fine, but I have a problem with the audio quality of the audio conferences. If a SIP phone enters a conference as the first participant, FreeSwitch sends back a very noisy audio to that phone. As soon as a 2nd SIP phone joins the same conference, the noise goes away. The same noise is there if all conference members are muted. I tried to disable all kinds of comfort noise (e.g. comfort-noise = -1 in conference.conf.xml) etc., but cannot get rid of that noise. My setup: - FreeSwitch 1.2.10, Windows, x86 compilation. - SIP calls with uLAW, ptime 20. - disabled all wave files in conference.conf.xml Any ideas, how to get rid of that noise? Thanks, Markus
Remove the comfort-noise param, and see if that helps. -1 might enable it actually. 2013/6/24 Markus von Arx <mkvonarx@gmail.com>

Thanks for the hint! I first tried with setting comfort-noise to "0" which did the trick. No (comfort) noise anymore. Maybe someone should fix the FreeSwitch wiki ( http://wiki.freeswitch.org/wiki/Mod_conference) where the documentation actually says "-1 (total silence)".

Done. BTW, the wiki is open for the public to edit so feel free to fix any errors you happen to find. -MC
