We have a couple of TA7102 terminal adapters that work wonderfully for voice, but when I tried to connect them to local fax machines, the faxes are failing. I thought it was a SIP trunk issue until I attempted to send faxes internally and received the same failure. When I dial the fax number, I hear the outbound fax tome start, I hear it ring the far end, but as soon as the far end answers with a fax signal, I receive a busy tone and the call drops. I have made a couple of minor changes in the media setting with no affect.
The locations that fax in our campus system are remote to the MXE III, so analog extensions off the back is not available.

I would start by disabling T.38 on the ATA
-
OK, I'll try that
-
I disabled T.38 to no effect internally or externally...far end answers with fax response, I get a busy signal and the call drops.

I was able to solve the issue from another forum.
Mitel HO2643 settings solved my issue of busy on answer.

Not sure what setting was wrong, let us know

I would also disable G.729 if you disable T.38 so it forces 711.

set up authentication under the SIP tab.
Use the dropdown to select "username" under Priority Criteria.
put in the extension number under "Username Criteria".
Disable Validate Realm.
Put the extension number under User Name and then the password must match what you put in the PBX.
under the registration tab select "Enable" from the drop down for both register and messaging.
