The phone will need to be able to reach the PBX direct to receive its configuration files and VPN information. Once it has the information and the phone is rebooted it should use the VPN for all future communications with the PBX for SIP and Phone Apps only. The only thing the phone will communicate with the PBX NOT on the VPN is listed below, as it will still use the IP address you have setup in your template for your phones in EPM as the VPN on the phone is started after it checks for the following information.
- Configuration File updates
- Firmware Updates
- VPN Cert Updates
