Monitoring the Cisco Unified Wireless IP Phone Remotely


Each Cisco Unified IP Phone has a web page from which you can view a variety of information about the phone, including:

Home—Summary information about the phone

Setup—Configurable settings for network profiles, USB port, and trace data

Information—Network and device static information

Statistics—Wireless LAN and IP network data

Stream Statistics—Displays counters and statistics for the current call

System—Configurable settings for trace logs, backup, phone upgrades, and web page password

You can use Setup pages and System pages to configure settings for the Cisco Unified Wireless IP Phone 7921G. For information about using these web pages, see Chapter 4, "Using the Cisco Unified Wireless IP Phone 7921G Web Pages."

This chapter describes the information that you can view from the phone's web page. You can use this information to remotely monitor the operation of a phone and to assist with troubleshooting.

You can also obtain much of this information directly from a phone. For more information, see Chapter 7, "Viewing Security, Device, Model, and Status Information on the Phone."

For more information about troubleshooting the Cisco Unified IP Phone, Chapter 9, "Troubleshooting the Cisco Unified Wireless IP Phone 7921G."

Accessing the Web Page for a Phone

To access the web page for a Cisco Unified IP Phone, follow these steps:

Procedure


Step 1 Obtain the IP address of the Cisco Unified Wireless IP Phone 7921G using one of these methods:

Search for the phone in Cisco Unified CallManager by choosing Devices > Phones. Phones registered with Cisco Unified CallManager display the IP address on the Find and List Phones web page and at the top of the Phone Configuration web page.

On the Cisco Unified Wireless IP Phone 7921G, press Settings > Device Information> Network and then scroll to the IP Address option.

Step 2 Open a web browser and enter the following URL, where IP_address is the IP address of the Cisco Unified IP Phone:

https://<IP_address>


Note When the Security Alert dialog box displays a notice to accept the Trust Certificate, click Yes or Always to accept the application.


Step 3 Log in to the web pages with username: admin and enter the password: Cisco for the phone web pages.

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 the "Monitoring the Voice Quality of Calls" section on page 9-17

Note The MOS LQK score can vary based on the type of codec that the Cisco Unified IP Phone uses.

Avg MOS LQK

Average MOS LQK score observed for the entire voice stream

Min MOS LQK

Lowest MOS LQK score observed from start of the voice stream

Max MOS LQK

Baseline or highest MOS LQK score observed from start of the voice stream

These codecs provide the following maximum MOS LQK score under normal conditions with no frame loss:

G.711 gives 4.5

G.729 A /AB gives 3.7

MOS LQK Version

Version of the Cisco proprietary algorithm used to calculate MOS LQK scores

Cumulative Conceal Ratio

Total number of concealment frames divided by total number of speech frames received from start of the voice stream

Interval Conceal Ratio

Ratio of concealment frames to speech frames in preceding 3-second interval of active speech. If using voice activity detection (VAD), a longer interval might be required to accumulate 3 seconds of active speech

Max Conceal Ratio

Highest interval concealment ratio from start of the voice stream

Conceal Secs

Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds)

Severely Conceal Secs

Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream
