Hi,
I have a Sangoma S206 phone which was working using the Auto Provisioning feature at a remote site just fine.
I haven’t made any changes to FreePBX other than module upgrades and the same with router configs, and not the phone will not register.
I think it has something to do with the phone not sending the external IP address in the SIP header although Sangoma support thinks the port is blocked.
I have two older Aastra phones which are hard configured and they are registering fine.
Here are sample SIP Headers (IP addresses mangled by me for this post):
What I’m seeing on the Aastra is a message header with the external IP address:
Via: SIP/2.0/UDP 9a.8b.3c.2d:5060;branch=z9hG4bK5ab8dee7;rport
Max-Forwards: 70

When I look at the Sangoma, the message header is showing the Internal address:
Via: SIP/2.0/UDP 192.168.0.171:5060;branch=z9hG4bK2750037179

Anyone have any ideas?
