VoIP Faxing

Post by dharding »

Does the Allworx 48x support T.38 protocol? We would like to configure for VoIP faxing.

I haven't seen anything about T.38 in the Allworx.
You could try to configure without it and see what happens... might not be reliable though.

I have successfully used a Grandstream HT701 SIP ATA for faxing purposes. Supports T.38.
If you try that, you may need to change this setting to Yes: Loop Current Disconnect. Without that the ATA wouldn't hang up properly when the fax was complete. May be dependent on SIP provider.
