Steve,

Can you kindly elaborate on that. As I mention in my original post, I
understand that it is possible for calls comming in on a Zap channel, but my
tests and wiki documentation suggest that it is limited to that.

If you can shed some more light on this I would be greatful.

should something like this work ? if the incomming call is from a SIP
channel

 [default]
 exten => s,1,Answer
 exten => s,2,Dial(IAX2/3987,40,r)
 exten => s,3,Hangup

 exten => fax,1,SetVar(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
 exten => fax,2,rxfax(${FAXFILE})


Thanks
