[Asterisk-Users] Echo Cancellation not working in Zapata.conf

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:

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

Channel: 1*CLI>

File Descriptor: 25

Span: 1

Extension:

Dialing: no

Context: aheeva

Caller ID string:

Default law: ulaw

Here is my Zapata.conf:

 

; Zapata telephony interface

; Configuration file

 

[channels]

;

usecallerid=yes

hidecallerid=no

callwaiting=no

restrictcid=no

usecallingpres=yes

callwaitingcallerid=yes

transfer=no

cancallforward=yes

callreturn=yes

callerid=asreceived

;

relaxdtmf=yes

;

rxgain=0.0

txgain=0.0    

immediate=no

;

; Configure jitter buffers in zapata (each one is 20ms, default is 4)

;

jitterbuffers=4

;

 

context=aheeva

switchtype=national

signalling=pri_cpe

pridialplan=unknown   ; needed to pass proper # digits to PRI

echocancel=yes

echotraining=yes

echocancelwhenbridged=yes

group = 1

channel => 1-23

;channel => 25-48   

 

 

 

 

Thanks,
