Hi All, Is it possible to detect an incomming fax just as it is possible with Answer on a Zap channel. If not do others find the possibility of this enhancement useful too? Umar

See: http://www.opencall.org/faq/x47.html If you don't believe me, go ahead and actually *try* to send/receive a fax through a WAN/internet VoIP connection. You'll probably get tolerable results with SIP-fax on a LAN, but run it through a VoIP provider over the internet, and you'll have a mess, even if the codec is ULAW/ALAW What you really want is a T.38 channel driver.

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 Umar
