[Asterisk-Users] Sipura 841 echo cancel question

[Kris Boutilier]

You're probably looking for the 'echotraining' facility specified in
/etc/asterisk/Zapata.conf. From that file:

 

; In some cases, the echo canceller doesn't train quickly enough and
there

; is echo at the beginning of the call.  Enabling echo training will
cause

; asterisk to briefly mute the channel, send an impulse, and use the
impulse

; response to pre-train the echo canceller so it can start out with a
much

; closer idea of the actual echo.  Value may be "yes", "no", or a number
of

; milliseconds to delay before training (default = 400)

;

;echotraining=yes

 

Hope that helps.

Hi there, 

 

I'm new to asterisk and hoping you can help out. I have a small
deployment of asterisk running. 4 sipura 841 phones and a linux box with
a digium TDM400P.  When a user makes a call there is usually echo for
about 15 seconds and then it goes away. I have read through all the echo
stuff and to be honest totally confused.  Not sure what to set or how to
test. 

 

Any guidance totally appreciated !  Thanks in advance ! 

Nora
