[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: 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 Channel: 1*CLI> File Descriptor: 25 Span: 1 Extension: Dialing: no Context: aheeva Caller ID string: Destroy: 0 InAlarm: 0 Signalling Type: PRI Signalling Owner: <None> Real: <None>LI> Callwait: <None> Threeway: <None> Confno: -1 Propagated Conference: -1 Real in conference: 0 DSP: no Relax DTMF: yes Dialing/CallwaitCAS: 0/0 Default law: ulaw Fax Handled: no Pulse phone: no Echo Cancellation: 128 taps, currently OFF PRI Flags: PRI Logical Span: Implicit Actual Hookstate: Onhook Here is my Zapata.conf: ; Zapata telephony interface ; ; Configuration file [channels] ; usecallerid=yes hidecallerid=no callwaiting=no restrictcid=no usecallingpres=yes callwaitingcallerid=yes threewaycalling=no 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, Alberto The contents of this email message and any attachments are confidential and are intended solely for addressee.

[Asterisk-Users] Echo Cancellation not working in Zapata.conf
Nevermind. It turns out that if you are not on an active call on the channel, the "zap show channel x" shows OFF by default. After placing a call and checking the channel, it showed "Echo Cancellation: 128 taps, currently on" as it should. So our setup is correct after all.

Your show zap channel output shows it's on-hook, so the DSP and echo canceller will be off. Are you actually having issues or are you falling into the trap of overanalyzing everything? -A.
