[Freeswitch-users] Can't get fax working

[Boris Kovalenko]

Hello!

     After digging I found that problem is with Audiocodes.
Kapanga SoftPhone --- FS -- Cisco 5350 -- PSTN -- fax is working
Kapanga SoftPhone -- FS -- VOIP clould --- fax is working
Kapanga SoftPhone -- FS -- AudioCodes MP-11x -- fax is not working....

So may be there is somebody who may help with AudioCodes configuration?
