[Freeswitch-users] T.38 and Audiocodes or Patton gateway

[Tim St. Pierre]

Hello,

I am trying to get a reliable fax setup working.

I have set up a nice fax receiver mechanism with mod_spandsp and it works very well when I send a
fax using a Linksys SPA2102

I have poor results with Audiocodes MP202B, and can't get anything to work with a Patton M-ATA

I have a number of Audiocodes MP202B in service and would rather not replace them if I can avoid it.

In each case, the fax fails with "communications error" on the sending machine, and "Call hungup
prematurely" on the SpanDSP side.

There aren't too many knobs on the gateways.  Are there any knobs in mod_spandsp that might help
this condition?  Anyone else have any experience with these devices?

Thanks!
