In this example faxdetect is overwriting the DID.

So the trick then would be to somewhere early-on in your dialplan grab 
the DID into some variable, and then restore it after the fax detection 
occurs...

[default]
exten => _X.,1, SetVar(ORIGEXTEN=${EXTEN})
exten => s,2,Wait(3)
.....
exten => fax,1,Dial(IAX2/ttyIAX0/${ORIGEXTEN})
