Understanding Security Profiles
A security profile defines whether the phone is non-secure, authenticated, encrypted, or protected. Every
Cisco Unified IP Phone that is supported by Cisco Unified Communications Manager Administration
has a security profile. For information about configuring the security profile and applying the profile to
the phone, see Cisco Unified Communications Manager Security Guide.
For Cisco Unified IP Phones using Cisco Unified CallManager 4.3 and later, security is configured on
Note
each phone. For more information about configuring security, see Cisco Unified CallManager Security
Guide at
