The only solution we found is to set faxdetect=no in the sip.conf of the 
peer definition. The Set(FAXOPT(detect)=[yes|no]) command in the 
dialplan is not taken in account.

The problem with this solution is that we can't mix fax reception with 
direct fax line and fax detection on audio line. Or better said, to use 
a mix of those detection, we should put a Wait(x) in the fax direct DID 
and systematically use the fax extension to dial hylafax like

[FAXDirectDID]

exten = fax,1,Dial(IAX2/300,,)
  same = n,Hangup

exten = _X.,1,Wait(10)
  same = n,Congestion()

Not particulary clean.
