Cisco Unified CallManager Administration groups security-related settings in the SCCP phone security profile, which works like a template; that is, you configure the settings in the profile and then apply the profile to the SCCP phone. After you apply the profile to the phone, it uses the settings that you configured in the SCCP Phone Security Profile window. If you want to do so, you can use the same profile for many SCCP phones, which eliminates having to configure the same fields multiple times.
The SCCP Phone Security Profile window includes security-related settings such as Device Security Mode, Authentication Mode (for CAPF), and Key Size (for CAPF).
Tip All SCCP phones require that you apply a security profile.
For information on configuring and applying a SCCP phone security profile, refer to the Cisco Unified CallManager Security Guide.
