One component of the echo that you are hearing is likely caused by poor acoustic isolation in the headset of "the caller" that you described. It might be eliminated by having "the caller" adjust their mic levels down slightly. Better quality headsets usually have better acoustic isolation properties too.
-----Original Message----- From: Davin O'Neill Sent: Thu, May 26, 2005 8:49 am I have Asterisk running on my LAN with softphone clients (SJPhone) and > Cisco 7940/60s, all using SIP. I also have a few remote sites connecting to my Asterisk server. I am getting an echo back of my voice when talking with one particular site. The caller does not hear an echo on their end. All calls on the LAN or to other sites do not produce an echo. When the > caller places his SJPhone on mute there is no echo. The caller is using a > standard PC headset and not a speakerphone. I've tried turning on echocancel and echotraining in the Zapata configuration, but it had no effect. The website below states that two IP phones going through Asterisk should not result in a noticeable echo, instead this is more common when > connecting to PSTN lines. The echo is about 500ms, faint but distracting. Any suggestions would be greatly appreciated. http://www.voip-info.org/wiki-Asterisk+Echo+Avoidance Thanks! _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
