I’m new to this whole PBX thing and we are having a tough time getting faxing on our PBX to be reliable. I know our carrier supports t38, but how can I verify that it is being used?
Or, should be using something else than freepbx for faxing?
We currently have AsteriskNOW with FreePBX 2.8.0.4 and Asterisk 1.6.2.15.
