[cisco-voip] VG224 + SCCP + FAX + CCM4.1(3) supported?

[Lelio Fulgenzi]

I think you have to enable modem/fax passthrough first on your gateways (if accepting incoming faxes).

The enable modem/fax passthrough on your VG224s.

And then the important thing is to disable Super G3 or otherwise disable ECM and set speed to 14.4kbps.

I'm sure Scott V. will add some additional good pointers, but this is what I did and did multiple successful tests both onnet and offnet.
