First off you are using G729, this compresses the audio and you will lose some quality. I would recommend that any internal calls or calls between an IP endpoint and a local trunk use an uncompressed protocol, such as G.711. If these faxes are coming in on trunks local to the fax machine, you should be able to use an uncompressed codec, offering the best quality. If you are concerned with LAN bandwidth, you can assign all the IP phones to use G.729, but all other calls (fax/modem) would be G.711. There are a few ways to accomplish this depending on your situation.

Also, on page 3, Fax should be set to Pass-through. I don't remember which Avaya doc says this.
