I got this system which was using FreePBX 13. I did a backup of FreePBX, and moved it over to FreePBX 15 (restored). I shut the old system down,then rebooted the new one using the same public IP address as the old one.
Now after the new system is up, every single call to any extension is going to voicemail. I have both chan_sip and chan_pjsip extensions, and even some extensions connecting via OpenVPN client on the telephone, and all are having the exact same issue.
It is using Asterisk 16.x.x, but then tried downgrading to asterisk 13 for a bit. Still getting same result as before.
Outbound calls functioning as expected.
Here is a paste of a test call from extension 299 to 296
Also interesting is looking at sngrep I see the following
2020/10/16 21:27:00.834789 220.127.116.11:5060 -> 18.104.22.168:38416

Anyone got some ideas on this?
