I’m having a bit of trouble setting up inbound fax from Flowroute on FreePBX184.108.40.206 with Asterisk 16.15.1. In the CLI, I see: FAXSTATUS=“FAILED: error: statusstr: OK”. Below is the call flow from a packet capture I did, and I’m noticing it says no-signal a lot, which I’m thinking is the issue, but I’m not sure how to fix it. The sending fax machine shows the fax was sent successfully every time. I opened UDP ports 4000-4999 on my firewall and have set T.38 passthrough = yes in Asterisk General SIP settings as well but not sure if that was necessary. The goal here is to have the inbound fax emailed as a PDF to the user.
This is my first time setting up fax on FreePBX so any help would greatly be appreciated!
