[Asterisk-Users] FAX difference IAXModem / Hylafax and spandsp app_rxfax

[James Armstrong]

I looked into why I can't get the original DID number called when a fax 
is detected (so I can later route to the correct email address). There 
is a variable called FAXEXTEN that is created when a fax is detected, 
but it is not being populated with the original extension / did number 
called. It always has 's' as the original extension. Does anyone know 
how to fix this? I just want to use the zap fax detection so each person 
can have their personal DID number accept faxes and calls, then route 
the fax to their email address based on the DID number called.
