Thanks but Answer() didn't help:

     -- Executing [s at incoming-fax:1] Set("SIP/side-sip-fax-00000002", 
"FAXFILE=/var/spool/asterisk/fax/20100508_1027") in new stack
     -- Executing [s at incoming-fax:2] Answer("SIP/side-sip-fax-00000002", 
"") in new stack
     -- Executing [s at incoming-fax:3] 
ReceiveFAX("SIP/side-sip-fax-00000002", 
"/var/spool/asterisk/fax/20100508_1027.tif") in new stack

transmitting fax. result=48: Disconnected after permitted retries.

If you could, I'd appreciate your sharing your working setup so I can 
just duplicate it.
