asterisk users - Jan 2005 - Enabling/disabling zaptel echo-can from dialplan.

Is it possible to enable/disable the zaptel echo-canceller
from the dialplan?

The reason I ask is that I want the echocanceller active on all calls except
when someone is sending a fax.
The simplest way would be to disable it on incoming calls to the fax
numbers and leaving it on on all other calls.

I don't think it is possible to control from the dialplan at the moment.  
The echo canceler should deactivate itself when it senses a fax 2.1kHz
guard tone on the line.
