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!

Doug
