Description
Ensures that all SCCP and SIP signaling messages
sent between the phone and the Cisco Unified
Communications Manager server are encrypted.
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.
Ensures the privacy of phone configuration files.
Prevents access to a phone web page that displays a
variety of operational statistics for the phone.
The following is an additional security option that
you control from Cisco Unified Communications
Manager:
• Disabling access to web pages for a phone
Defines the use of 802.1X authentication to request
and gain access to the network.
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.
Note The MOS LQK score can vary based on
the type of codec that the
Cisco Unified IP Phone uses.
Average MOS LQK score for the entire voice stream.
Lowest MOS LQK score from the start of the voice
stream.
