Phone Downloads Configuration
This part is extremely important. The phone must download the configuration (including the certificate hash in Base64) while it is inside the network and has direct access to the CUCM TFTP server.
The phone has to be provisioned inside the network before it can be moved outside the network and use the VPN feature.
Phone Connects to ASA
After internal provisioning has been completed, the phone can be moved to the external network for VPN access. Here the Corporate Phone has been moved to a Home location.
