[Asterisk-Users] HOW TO RECEIVE FAX

[Mark Phillips]

How are these faxes arriving in your * server?

If you have a line handler card like the TE400 types then this should 
not be a problem. If you are getting your faxes from a VoIP service like 
  Broadvoice then you should make sure that you are usling ULAW as the 
codec. Anything else will conpress the fax tones and when uncompressed 
by your * server they will not work.

Having said that, Ulaw may also not work. Many folks have no problems 
with using ULaw for their VoIP prover codec  but some folks do.
