Assuming you're getting the calls on some sort of a Zap channel, then in 
the same context where your extention is defined, add:

exten => fax,1,Hangup

or even better yet:

exten => fax,1,Background(if-this-really-is-a-human-please-press-1)
exten => fax,2,Hangup

You must also have:

faxdetect=incoming

In zaptel.conf for this to work.

Hope this helps,
Gilad
