Hello All This or similar topics have already been mentioned but without any solution yet. I have built a oneway conference system for a client using one caller's input and broadcast it to all the other participants using app_meetme. E.g. one talker multiple listeners. Unfortunately some of the talkers (I have got multiple rooms) are not loud enough (e.g. use just half the amplitude, so making it louder by factor of 2.0would be necessary). My question: Is there a possibility in asterisk-1.4 to double/quadrouple the loudness of a channel's input/output using chan_sip? All clients come in via chan_sip so using another channel type is no solution in my situation. I use G711ulaw only. Btw: I would be very glad if someone could point me to a solution of this. Kind regards, Andreas Brodmann -------------- next part -------------- An HTML attachment was scrubbed...
