I was recently notified that we are no longer receiving faxes. The call comes through, and the fax machine indicates 'receiving', but the call is dropped part way through. This happens 100% of the time.
We use a SIP trunk into our Asterisk PBX (AsteriskNOW 3.0 v11.5.1), and the analog fax machine is connected to the PBX via a Linksys SPA8000 SIP ATA.
Faxes previously worked fine, and I suspect the issue is due to the recent upgrade of the Digium Add-ons module for FreePBX. Has anyone else experienced these issues?
*update - we're using Free Fax for Asterisk
