Model Information, Status, and Statistics

Model Information, Status, and Statistics

This chapter describes how to use the following menus on the Cisco Unified SIP Phone 3905 to view model information, status messages, and network statistics for the phone:

  • Model Information screen: Displays hardware and software information about the phone.
  • Status menu: Provides access to screens that display the status messages, network statistics, and statistics for the current call.

You can use the information on these screens to monitor the operation of a phone and to assist with troubleshooting.

You can also obtain much of this information, and obtain other related information, remotely through the phone web page. For more information, see Remote Monitoring

For more information about troubleshooting the Cisco Unified SIP Phone 3905, see Troubleshooting and Maintenance

        Access Call Statistics Screen

        You can access the Call Statistics screen on the phone to display counters, statistics, and voice-quality metrics of the most recent call.


        Note


        You can also remotely view the call statistics information by using a web browser to access the Streaming Statistics web page. This web page contains additional RTCP statistics not available on the phone. For more information about remote monitoring, see Remote Monitoring


        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 latest voice stream, perform these steps:

        Procedure
          Step 1   Press Applications.
          Step 2   Select Admin Settings.
          Step 3   Select Status.
          Step 4   Select Call Statistics. Call Statistics Fields describes the fields in the screen.
          Step 5   To exit the Call Statistics screen, press Back .

          Call Statistics Fields

          The following table contains the fields in the Call Statistics screen.

          Table 3 Call Statistics Items for the Cisco Unified SIP Phone 3905

          Item

          Description

          Rcvr Codec

          Type of voice stream received (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law.

          Sender Codec

          Type of voice stream transmitted (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law.

          Avg Jitter

          Estimated average RTP packet jitter (dynamic delay that a packet encounters when going through the network) observed since the receiving voice stream was opened.

          Max Jitter

          Maximum jitter observed since the receiving voice stream was opened.

          Voice Quality Metrics

          MOS LQK

          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
          • G729A/AB: 3.7

          MOS LQK Version

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

          Latency

          Estimate of the network latency, expressed in milliseconds. Represents a running average of the round-trip delay, measured when RTCP receiver report blocks are received.
