I don’t know if the VPN server is running or not for yours, but my issue that I posted here on the forums: (Only EPM “custom” provisioning address works, not “external”) was that it seems there is a bug with FreePBX not actually redirecting to the external IP in the EPM settings when you select the “External” option. No one has replied. My fix, after many many hours of troubleshooting, was to MANUALLY specify the external address in the “Custom” field. After that, the phones successfully grabbed the provisioning and VPN correctly
