For information about using these web pages, see Chapter 4, "Using the Cisco Unified Wireless IP Phone 7925G Web Pages." For more information about troubleshooting the Cisco Unified IP Phone, Chapter 10, "Troubleshooting the Cisco Unified Wireless IP Phone 7925G."

Accessing the Web Page for a Phone

To access the web page for a Cisco Unified Wireless IP Phone 7925G, perform the following steps.

Procedure

---

Step 1 Obtain the IP address of the Cisco Unified Wireless IP Phone 7925G using one of these methods:

•Search for the phone in Cisco Unified Communications Manager by choosing Devices > Phones. Phones registered with Cisco Unified Communications Manager 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 7925G, 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.

The Stream Statistics menu provides information about two types of streaming. The first stream is RTP Statistics and the second stream is Voice Quality Metrics. Table 9-6 description each field displayed in the Stream Statistics window.

Table 9-6 Stream Statistics Items 

Item	Description
RTP Statistics
Domain Name	Domain of the phone
Remote Port	Port number of the destination
Local Port	Port number of the phone
Receiver Joins	Number of times the phone has started receiving a stream
Host Name	Host name for the phone
Sender Packets	Number of RTP voice packets transmitted since voice stream was opened Note This number is not necessarily identical to the number of RTP voice packets transmitted since the call began because the call might have been placed on hold.
Sender Tool	Type of audio encoding used for the stream: G.729, G.711 u-law, G.711 A-law, or Lin16k
Sender Report Time	Internal time stamp indicating when this streaming statistics report was generated
Receiver Octets	Total number of octets received by the phone
Receiver Lost Packets	Number of missing RTP packets (lost in transit)
Receiver Reports	Number of times this streaming statistics report has been accessed from the web page (resets when the phone resets)
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 "Resolving Voice Quality and Roaming" section on page 10-8 Note The MOS LQK score can vary based on the type of codec that the Cisco Unified IP Phone uses.
Min MOS LQK	Lowest MOS LQK score observed from start of the voice stream
MOS LQK Version	Version of the Cisco proprietary algorithm used to calculate MOS LQK scores
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
Conceal Secs	Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds)
