Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Security Configuration Menu
VPN Configuration
The VPN Configuration menu allows you to enable a virtual private network (VPN) connection using
the Secure Sockets Layer (SSL) when a phone is located outside a trusted network or when network
traffic between the phone and Cisco Unified CM crosses untrusted networks.
Note
VPN Client is supported only for the Cisco Unified IP Phone 7942G, 7945G, 7962G, 7965G, and 7975G.
Your system administrator configures the VPN Client feature as needed. If it is enabled and the VPN
Client mode is enabled on the phone, you are prompted for your credentials as follows:
•
If your phone is located outside the corporate network—You are prompted at login to enter your
credentials based on the authentication method that your system administrator configured on
your phone.
•
If your phone is located inside the corporate network—
–
If Auto Network Detection is disabled, you are prompted for credentials, and a VPN connection
is possible.
–
If Auto Network Detection is enabled, you cannot connect through VPN so you are
not prompted.
Connecting to VPN
Use this procedure to access the VPN Configuration settings and connect through VPN.
