Sorry for bringing so old topic, but what should I put in 
extensions.conf for receiving faxes? Is

exten => 1234567,1,rxfax(/home/steveu/testfax.tif)

enough or do I have to answer the call before or something else?

When I'm dialing my number handled by Asterisk, there is a fax signal 
but the fax machine doesn't start sending. What can be wrong?
