asterisk users - Sep 2008 - Selectively disable echo cancellation?

Hi, all.  I have a Sangoma A104D (on-board, DSP-based echo can); I'm
currently passing through some of my in-bound calls to a legacy PBX (which
I hope to eventually replace).  That being said, until I do, I'd like to
kill echo cancellation for the passed-through calls -- I don't want to
mess with their fax reception.

Any idea how to do this?

Thanks!

Is

           echocancelwhenbridged=no

inside zapata.conf what are you looking for?

If not, what I figured out is if you run

   System(wan_ec_client wanpipe1 disable ${VALUE}) ;

in your dialplan logic [perhaps inside a macro called with the M()
option for Dial()] would do the trick.

Don't forget that you obtain "Zap/${VALUE}-1" from ${CHANNEL}
(using
some variable stripping) and to run

   System(wan_ec_client wanpipe1 enable ${VALUE}) ;

at Hangup.
