[Asterisk-Users] echotraining on T1 circuits

[Mike Benoit]

I don't use T1's, only regular lines, but echotraining works with any
zaptel interface as far as I know.

I would try echotraining=yes and echotraining=800 (if your using a
relatively new CVS version).

I personally haven't noticed any "pause" when using echotraining, I
think its less then 1 second, but not 100% sure on that.

Also, you didn't mention if it was near end echo, or far end echo your
hearing.
