[asterisk-users] Selectively disable echo cancellation?

[Ken D'Ambrosio]

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!
