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 "Nahid Hossain" <[EMAIL PROTECTED]> wrote in message news:!~!UENERkVCMDkAAQACAAAAAAAAAAAAAAAAABgAAAAAAAAABittf/[EMAIL PROTECTED] Hi, I want to do FAX through Asterisk with the following scenario: Fax Machine ------àNortel PBX -------à E1 (euro-isdn) -------à Asterisk -----à SIP -----àAsterisk--------à E1 (euro-isdn)-----àNortel PBX------à Fax Machine Is there anyone who can help me to configure the above scenario without any extra application/software.
