[Freeswitch-users] Can't get fax working

[Yehavi Bourvine]

Hello Boris,

  It seems like your Audiocodes is misconfigured. I had a different problem
which might be (or not) related to your problem: Both FS and Audiocodes
asked for T.38 and it didn't work.

Do you have T38 enabled in FreeSwitch? If so, try the following at your MP:
- At the Fax/Modem screen disable all fax and modems protocols.
- At all other screens set the fax protocol to be T.38
- Add the T.38 codec.

I hope this helps.

                           __Yehavi:
