yes, it improves the success.. An ATA IS a gateway. As far as success rates, depends on the quality of the connection. On May 1, 2014, at 12:39 PM, Sean Devoy <sdevoy@bizfocused.com> wrote:

For the purposes of my questions please assume I am faxing FROM a fax machine over IP into the FS where I will “capture” it using <action application="rxfax" data="//my_directory//rxfax.tiff"/>
Does a T.38 capable ATA improve the success rate of sending a fax from the ATA just into FreeSwitch?
I have always thought T.38 was something you put on your Gateway Lines and I think I have forgotten my ATAs connections.
Also, what success rate have you had with end-to-end delivery of FAXes using T.38? This accountant has heard FAXing is not reliable over VOIP. So far, I think I agree with him. Does T.38 really fix the problem?
