I have echocancel=yes in zapata.conf but when I do a zap show channel 1,
I notice echo cancellation is turned off.
I followed the article that talks about the order in which the
statements need to be in zapata.conf to get echo canceling to work:
http://lists.digium.com/pipermail/asterisk-users/2005-June/110615.html
But it is still not working. Does anyone know how to get echo
cancellation to work?
We have Asterisk 1.0.7 and Zaptel 1.0.9 with 2 PRIs using a TE410P
board.
Here is the output from the CLI:
zap show channel 1
