Secure Phone Call Identification

A secure call is established when your phone, and the phone on the other end, is configured for secure calling.
The other phone can be in the same Cisco IP network, or on a network outside the IP network. Secured calls
can only be made between two phones. Conference calls should support secure call after secure conference
bridge set up.
A secured call is established using this process:
1. A user initiates the call from a secured phone (secured security mode).
2. The phone displays the secure icon
for secure calls, but this does not mean that the other connected phone is also secured.
