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

[Yehavi Bourvine]

Hi,

  So which ATA is recommended for T.38 FAX support? We have Audiocodes and
also have poor results (the gateway to the PSTN is Cisco). I got now
VegStream which I am going to test also.

                         Thanks, __Yehavi:
