Remote Monitoring

Remote Monitoring Overview

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

  • Device information
  • Network setup information
  • Network statistics
  • Device logs
  • Streaming statistics

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 Cisco Unified IP Phone Model Information, Status, and Statistics

For more information about troubleshooting the Cisco Unified IP Phone, Troubleshooting and Maintenance

Access Web Page for Phone

To access the web page for a Cisco Unified IP Phone, perform these steps.

If you cannot access the web page, it may be disabled. See Control Web Page Access for more information.

Procedure
    Step 1   Obtain the IP address of the Cisco Unified IP Phone using one of these methods:
    1. Search for the phone in Cisco Unified Communications Manager by choosing Device > Phone. Phones registered with Cisco Unified Communications Manager display the IP address on the Find and List Phones window and at the top of the Phone Configuration window.
    2. On the Cisco Unified IP Phone, press Applications, choose Administrator Settings > Network Setup, 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

    Control Web Page Access

    For security purposes, access to the web pages for a phone is disabled by default. This practice prevents access to the web pages that are described in this chapter and to the Cisco Unified Communications Manager Self Care Portal.


    Note


    Some features, such as Cisco Quality Report Tool, do not function properly without access to the phone web pages. Disabling web access also affects any serviceability application that relies on web access, such as CiscoWorks.


    To enable or disable access to the web pages for a phone, perform these steps from Cisco Unified Communications Manager Administration:

    Procedure
      Step 1   Choose Device > Phone.
      Step 2   Specify the criteria to find the phone and select Find, or select Find to display a list of all phones.
      Step 3   Select the device name to open the Phone Configuration window for the device.
      Step 4   Scroll to the Product Specific Configuration area.
      Step 5   To enable access, from the Web Access drop-down list, choose Enabled.
      Step 6   To disable access, from the Web Access drop-down list, choose Disabled.
      Step 7   Select Apply Config.

      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.

      Avg MOS LQK

      Average MOS LQK score for the entire voice stream.

      Min MOS LQK

      Lowest MOS LQK score from the start of the voice stream.

      Max MOS LQK

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

      The following codecs provide the corresponding maximum MOS LQK scores under normal conditions with no frame loss:

      • G.711: 4.5
      • G.722: 4.5
      • G.728/iLBC: 3.9
      • G729A/AB: 3.7

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

      When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.
