Fact of the matter is faxing through Asterisk Appliance is a no go. Even using an ATA adaptor in between the fax machine and the Asterisk Appliance didn’t handshake. Sending and receiving.
Workaround: Since we had a FreePBX running, we registered the ATA to this server instead of the Asterisk Appliance and viola…it works like a charm (although sending faxes seem to be a little tricky..sigh)
Anyway, just an update
