ata186 to ata186 fax problem

[daemon_sid]

Hi,

We are using CCM 4.3.1 for voip. and have some problem with fax receptions. Fax goes from one ata186 in our ccm to another and some strings in text are missing, fax goes outside of our network through vg as5400 and the pictures are same. We try to configure ata for fax detect for only g711 and nothing helps.

Something to check first:

1. Is the gateway with the right load?

2. If using T1 line, is the clock set as external?

3. Are the fax relay and T38 disabled in gateway?

Try:
