DescriptionFeature
Ensures that all SCCP and SIP signaling messages
sent between the phone and the Cisco Unified
Communications Manager server are encrypted.
Signaling encryption
Implements parts of the certificate generation
procedure that are too processing-intensive for the
phone, and interacts with the phone for key generation
and certificate installation. The CAPF can be
configured to request certificates from
customer-specified certificate authorities on behalf of
the phone, or it can be configured to generate
certificates locally.

Defines whether the phone is nonsecure, authenticated,
encrypted, or protected.

Voice Quality Metrics
Objective estimate of the Mean Opinion Score (MOS)
for Listening Quality (LQK) that ranks audio quality
from 5 (excellent) to 1 (bad). This score is based on
audible-concealment events due to a frame loss in the
preceding 8 seconds of the voice stream.
The MOS LQK score can vary based on
the type of codec that the
Cisco Unified IP Phone uses.
