Send Fax using SIP

Hello,
 
I've been told that offramp-fax using MMOIP and VOIP dialpeers does not work. Since there is no DSP involved. See https://supportforums.cisco.com/message/3547247#3547247. 
 
Does anyone have information on how to send a fax using SIP? 
 
Kind regards,
 
Grant

If you like to use SIP , you need to use T.38 Pleas refer to the following Doc


http://www.cisco.com/en/US/docs/ios/voice/fax/configuration/guide/vf_cfg_fx_detect_ps6350_TSD_Products_Configuration_Guide_Chapter.html


The app_fax_detect.2.1.2.3.tcl script is used to automatically route single-number fax calls to an
MMoIP dial peer when configured in a T.37 fax store-and-forward environment or to a VoIP dial
peer in a T.38 fax relay environment.

Thanks.

I'm trying to implement a Mail2Fax application using our Cisco voice gateway and SIP. The gateway uses T.38 to send a fax using SIP, but I need software to initiate a fax call to the gateway. Anyone have an idea?

I think you can consult with local Cisco SE, they might have some idea.
