Flowroute is my provider.
All my outgoing calls are set to “private number”. Flowroute support notes that I am sending an invalid pjSIP header field. They see the From field containing the internal IP address of the freepbx server.
I can’t see where I have set this.
Any thoughts on how I might have screwed this up?
In the Trunk, set From Domain to sip.flowroute.com
Make sure that the outbound caller ID begins with the country code (+ is optional).
If you still have trouble, at the Asterisk command prompt type pjsip set logger on
make a test call and confirm the contents of the From header.
