Hi
Sounds to me like someone has changed a setting on the fax.
Maybe disabled auto-answer, or turned off audible ringing? It's difficult to say, as every fax machine is different.
If two ATAs do the same thing, and an analog phone on those ATAs is fine, then it suggests the hardware and config is OK.
Try swapping the cable from ATA--> FAX with the one from the analog phone in case that has developed a fault.
Otherwise, play with the fax menus; maybe find a factory reset on it or something.
Regards
Aaron
