What is the difference between phone VPN and CIsco proxy phone? I notice that in 9.x ASA that phone VPN is supported but no longer Cisco proxy phone.  What's the difference between the two methods of allowing outside phones to register to your CUCM server?

In short, the phones now have their own TLS VPN client built into their firmware. The provisioning is done now both in CM  and in the ASA, mostly the certificate exchange (ASA to CM and backwards).

Phone Proxy is the legacy method, no longer supported, ASA  VPN is the current choice.

Phones are provisioned in house first, then you take them out of the HQ and plug them to the home network. They request a URL resolvable from the INternet,and then they start talking to the ASA.

Thanks much. Sounds like I'll need to buy a few phones and start a rotation to the new method.
