Fax Pro outbound with virtual extension issues


(Jer Mul) #1

Hello,

We’ve been using Fax Pro with great results for the past few months but have recently ran into a problem. Our provider, Telnyx, implemented a new CID policy which rejects calls with incorrect info.

I had setup virtual extensions with the last 4 digits of the fax number as the username, then in the extension settings set the Outbound CID to the full number. This seemed to be working, or so I thought, until today when I received some calls about faxes not going through.

Looking at the logs I can see the call flows from my server sending only the username in the From header and not what I had set in the extension settings. I tried setting the outgoing station ID, and tried setting sendrpid=pai in the Trunk Outgoing Details.

Have you tried sending rpid instead of pai? Sendrpid=yes
