[Asterisk-Users] One way echo canceling?
Hey everybody, I have a situation where we have 2 Asterisk (CVS as of 08/25/2005) connected via IAX. On the corporate side, we have 1 TE110P connecting to a Definity G3R and it's connecting to a TN464F card, giving a 23 channel connection. I have echocancel=yes, echotraining=yes and echocancelwhenbridged=yes. One the remote office side, they a Adit 600 channel bank for 10 outside lines and is using a Point to Point T1 for communications between divisions. When there is a call on zap 1, from a sip phone on the remote office side and typing 'zap show channel 1' shows echo cancel is on, doing the same thing from the Definity to a SIP phone shows echo cancel off. Shouldn't it be on during a call on both the incoming and outgoing legs as long as it comes accross the PRI? Some (Myself included) have noted a slight echo on the Definity to SIP leg of the connection. My zapata.conf is below: switchtype = national context = incoming signalling = pri_cpe echocancel=yes echotraining = yes echocancelwhenbridged=yes overlapdial = yes group = 1 channel => 1-23 All suggestions would be welcome. Thanks!

I have not been able to confirm whether or not this is actually a bug. One possible fix is to disable overlapdial and see if echo cancellation is enabled after this. If it is, this might be a bug in chan_zap.c -- Matthew Fredrickson ___ --Bandwidth and Colocation sponsored by Easynews.com -- 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

It now shows as being enabled. Try updating to latest HEAD. I just fixed it this morning. It should work with overlapdial enabled now. Matt, This is working fine now! Thanks!
