[Asterisk-Users] Re: FAX with Asterisk

[Mick Hastings]

Hi Nahid,

I think youll want a fax on-ramp and off-ramp on your asterisk boxes instead 
of trying to send a fax using VoIP (SIP). I believe it is possible but not 
recommended. There are technical reasons for this that you can find online 
in many places.

Basically asterisk answers the fax and sends it to your fax program. the fax 
progam receives the fax, turns it into a TIFF file and emails it to the 
other end of your network. then the process is reversed and the TIFF is 
faxed via software out the T1 at the other end.

This process has a standard called T.37. Im not sure if there is currently 
support for this in asterisk or not (search the archieves) but its what I do 
with our Cisco router and a very neat little windows fax program called 
T37FSP from Sandler Consulting. You could prolly use the free version for 
testing.

hope this helps,
cheers,
Mick

Hi,

Fax Machine ------àNortel PBX -------à E1 (euro-isdn) -------à 
Asterisk -----à SIP -----àAsterisk--------à E1 (euro-isdn)-----àNortel

Is there anyone who can help me to configure the above scenario without any
