information about changing these options, see “Configuring DHCP Settings” section on page 5-5.)
Note
When the wireless IP phone is connected to a Cisco Unified Communications Manager Release 5.0 or
later, you can have multiple security profiles assigned to a phone. When the phone has more than one
security profile using different secure Cisco Unified Communications Manager clusters, you must delete
the CTL file from the current profile before enabling another profile. See “Understanding Security

You can access the Call Statistics screen on the phone to display counters, statistics, and voice quality
metrics in these ways:

•
During call—You can view the call information by pressing the Select button twice rapidly.
After the call—You can view the call information captured during the last call by displaying the Call

You can remotely view the call statistics information using a web browser to access the
Streaming Statistics web page. For more information about remote monitoring, see Chapter 9,
A single call can have multiple voice streams, but data is captured for only the last voice stream. A voice
stream is a packet stream between two endpoints. If one endpoint is put on hold, the voice stream stops
even though the call is still connected. When the call resumes, a new voice packet stream begins, and the
new call data overwrites the former call data.
To display the Call Statistics screen for information about the last voice stream, follow these steps:

Voice Quality Metrics
MOS LQK
Score that is an objective estimate of the mean opinion score (MOS)
for listening quality (LQK) that rates from 5 (excellent) to 1 (bad).
This score is based on audible concealment events due to frame loss
in the preceding 8-second interval of the voice stream. For more
information, see “Monitoring the Voice Quality of Calls” section on
page 10-11.
Note
The MOS LQK score can vary based on the type of codec

Min MOS LQK
Max MOS LQK
Average MOS LQK score observed for the entire voice stream.
Lowest MOS LQK score observed from start of the voice stream.
Baseline or highest MOS LQK score observed from start of the

MaxConcealRatio
Conceal Secs
Highest interval concealment ratio from start of the voice stream.
Number of seconds that have concealment events (lost frames) from
the start of the voice stream (includes severely concealed seconds).
