Err, if you start your extension definition with answer, then if it
detects a fax signal it will try to redirect to the extension fax.

With my limited testing, it seemed to work quite well. (not tried it
since moving to asterisk 1.4).

It is only neccesary if you want to detect faxes on VoIP communications
(without T.38).

If you want your machine to accept faxes via this method, it may be more
appropriate to use a SIP supplier that supports T.38 and look at using
callweaver instead of asterisk. (asterisk branch that supports T.38 fax
termination).
