[Asterisk-Users] Activate/Deactivate Hardware echo cancellation on TE406/TE411 when briging

[Boris Bakchiev]

Hi,

How would one activate/deactivate hardware echo cancellation on the
TE406 card?
Can it be done per channel?

I'm going to run TE406 in the following scenario:

ISDN -> TE406 -> PABX

I understand from Steve Underwood's site that echo cancellation is not
good for faxes (and they do that themselves).

So what I want to do and bypass echo cancellation for selected
extensions before bridging the calls from span1 to span2.

Thanks!
