I strongly disagree. :-) You dont want to do echo cancelation in userspace. Especially not on a non-realtime operating system. To make echo cancelation work it has to be as close to the line interface as possible. Also the frames have to be as small as possible. This rules out capi pretty much. best regards Klaus -- Klaus-Peter Junghanns _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
