Monitoring the Cisco Unified Wireless IP Phone Remotely

---

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

•Devices information

•Network configuration

•Network statistics

•Call statistics

•Wireless information

This chapter describes the information that you can obtain 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 8 "Viewing Status, Statistics, and Firmware Information on the Cisco Unified Wireless IP Phone 7920."

For more information about troubleshooting the Cisco Unified IP Phone, Chapter 10 "Troubleshooting the Cisco Unified Wireless IP Phone 7920."

Accessing the Web Page for a Phone

To access the web page for a Cisco Unified IP Phone, perform the following steps:

Procedure

---

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

•Search for the phone in Cisco Unified CallManager by choosing Device > Phone. 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, press Menu > Network Config > Current Config 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:

http://<IP_address>

Call Manager 1-5	Host names or IP addresses, in prioritized order, of the Cisco Unified CallManager servers with which the phone can register. An item can also show the IP address of an SRST router that is capable of providing limited Cisco Unified CallManager functionality, if such a router is available. For an available server, an item will show the Cisco Unified CallManager server IP address and one of the following states: •Active—Cisco Unified CallManager server from which the phone is currently receiving call-processing services. •Standby—Cisco Unified CallManager server to which the phone switches if the current server becomes unavailable. •Blank—No current connection to this Cisco Unified CallManager server. An item may also include the Survivable Remote Site Telephony (SRST) designation, which identifies an SRST router capable of providing Cisco Unified CallManager functionality with a limited feature set. This router assumes control of call processing if all other Cisco Unified CallManager servers become unreachable. The SRST Cisco Unified CallManager always appears last in the list of servers, even if it is active. An item will include a shield icon if the phone has an authenticated connection to the Cisco Unified CallManager server. It will display a padlock icon if the phone has an authenticated connection to the Cisco Unified CallManager server.
Authentication URL	URL that the phone uses to validate requests made to the phone web server.
Directories URL	URL of the server from which the phone obtains directory information.
Idle URL	URL that the phone displays when the phone has not been used for the time specified by Idle URL Time.
Idle URL Time	Amount of time in seconds that elapses before the URL shown in Idle URL appears.
Information URL	URL of the help text that appears on the phone.
Messages URL	URL of the server from which the phone obtains message services.

Call Statistics

A phone streams information when it is on a a call or running a service that sends or receives audio or data. The call statistics area on a phone's web page provides information about this stream. Table 9-4 describes the items in this area.

To display a network statistics area, access the web page for the phone as described in the "Accessing the Web Page for a Phone" section, and then click the Call Statistics hyperlink.

Table 9-4 Call Statistics Area Items 

Item	Description
MOS	Score that is an objective estimate of the mean opinion score (MOS) for listening quality 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. Note The MOS score can vary based on the type of codec that the Cisco Unified IP Phone uses.
Average MOS	Average MOS score observed for the entire voice stream.
Minimum MOS	Lowest MOS score observed from start of the voice stream.
Maximum MOS	Baseline or highest MOS score observed from start of the voice stream. These codecs provide the following maximum MOS score under normal conditions with no frame loss: •G.711 gives 4.5 •G.729 A /AB gives 3.7
Average Conceal	Total number of concealment frames divided by total number of speech frames received from start of the voice stream.
Current Conceal	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.
Maximum Conceal	Highest interval concealment ratio from start of the voice stream.
