Disabling ECM by FAR the WRONG thing to do and you have this mindset that is required its only required when you were hanging on by a thread doing G.711 Faxing over the public internet and you didn't want one tiny blip to screw the fax over. I still don't understand why Alex is doing t.38 gateway from audio to t.38? Either way ECM works fine never had any issues with it.

Turning off ECM is equivalent to saying "I use FAX, but I couldn't give a damn if they are received".
