        Message

        Description

        Possible Explanation and Action

        CFG file not found

        The name-based and default configuration file was not found on the TFTP Server.

        The configuration file for a phone is created when the phone is added to the Cisco Unified Communications Manager database. If the phone has not been added to the Cisco Unified Communications Manager database, the TFTP server generates a CFG File Not Found response.

        • Phone is not registered with Cisco Unified Communications Manager. You must manually add the phone to Cisco Unified Communications Manager if you are not allowing phones to auto-register. See Phone addition methods for details.
        • If you are using DHCP, verify that the DHCP server is pointing to the correct TFTP server.
        • If you are using static IP addresses, check the TFTP server configuration.

        CFG TFTP Size Error

        The configuration file is too large for the file system on the phone.

        Power cycle the phone.

        Checksum Error

        Downloaded software file is corrupted.

        Obtain a new copy of the phone firmware and place it in the TFTPPath directory. You should only copy files into this directory when the TFTP server software is shut down, otherwise the files may be corrupted.

        DHCP timeout

        DHCP server did not respond.

        • Network is busy. The errors should resolve themselves when the network load reduces.
        • No network connectivity between the DHCP server and the phone. Verify the network connections.
        • DHCP server is down. Check the DHCP server configuration.
        • Errors persist. Consider assigning a static IP address.

        DNS timeout

        DNS server did not respond.

        • Network is busy. The errors should resolve themselves when the network load reduces.
        • No network connectivity between the DNS server and the phone. Verify the network connections.
        • DNS server is down. Check the DNS server configuration.

        DNS unknown host

        DNS could not resolve the name of the TFTP server or Cisco Unified Communications Manager.

        • Verify that the host names of the TFTP server or Cisco Unified Communications Manager are configured properly in DNS.
        • Consider using IP addresses rather than host names.

        Duplicate IP

        Another device is using the IP address assigned to the phone.

        • If the phone has a static IP address, verify that you have not assigned a duplicate IP address.
        • If you are using DHCP, check the DHCP server configuration.

        File not found

        The phone cannot locate, on the TFTP server, the phone load file that is specified in the phone configuration file.

        From Cisco Unified Operating System Administration, make sure that the phone load file is on the TFTP server, and that the entry in the configuration file is correct.

        IP address released

        The phone has been configured to release its IP address.

        The phone remains idle until it is power cycled or you reset the DHCP address.

        Load ID incorrect

        Load ID of the software file is of the wrong type.

        Check the load ID assigned to the phone (from Cisco Unified Communications Manager, choose Device > Phone). Verify that the load ID is entered correctly.

        Load rejected HC

        The application that was downloaded is not compatible with the phone’s hardware.

        Occurs if you were attempting to install a version of software on this phone that did not support hardware changes on this newer phone.

        Check the load ID assigned to the phone (from Cisco Unified Communications Manager, choose Device > Phone ). Re-enter the load displayed on the phone.

        No default router

        DHCP or static configuration did not specify a default router.

        • If the phone has a static IP address, verify that the default router has been configured.
        • If you are using DHCP, the DHCP server has not provided a default router. Check the DHCP server configuration.

        No DNS server IP

        A name was specified but DHCP or static IP configuration did not specify a DNS server address.

        • If the phone has a static IP address, verify that the DNS server has been configured.
        • If you are using DHCP, the DHCP server has not provided a DNS server. Check the DHCP server configuration.

        TFTP access error

        TFTP server is pointing to a directory that does not exist.

        • If you are using DHCP, verify that the DHCP server is pointing to the correct TFTP server.
        • If you are using static IP addresses, check the TFTP server configuration.

        TFTP error

        The phone does not recognize an error code provided by the TFTP server.

        Contact the Cisco TAC.

        TFTP file not found

        The requested load file (.bin) was not found in the TFTPPath directory.

        Check the load ID assigned to the phone (from Cisco Unified Communications Manager, choose Device > Phone). Verify that the TFTPPath directory contains a .bin file with this load ID as the name.

        TFTP timeout

        TFTP server did not respond.

        • Network is busy. The errors should resolve themselves when the network load reduces.
        • No network connectivity between the TFTP server and the phone. Verify the network connections.
        • TFTP server is down. Check the TFTP server configuration.

        Timed Out

        Supplicant attempted 802.1X transaction but timed out to due the absence of an authenticator.

        Authentication typically times out if 802.1X is not configured on the switch.

        Version error

        The name of the phone load file is incorrect.

        Make sure that the phone load file has the correct name.

        XmlDefault.cnf.xml, or .cnf.xml corresponding to the phone device name

        Name of the configuration file.

        None. This is an informational message indicating the name of the configuration file for the phone.

          Display Call Statistics window

          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 Cisco IP Phone web page.


          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.

            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

              Check the load ID assigned to the phone (from Cisco Unified Communications Manager, choose Device > Phone ). Re-enter the load displayed on the phone.

              No default router

              DHCP or static configuration did not specify a default router.

              • If the phone has a static IP address, verify that the default router has been configured.
              • If you are using DHCP, the DHCP server has not provided a default router. Check the DHCP server configuration.

              No DNS server IP

              A name was specified but DHCP or static IP configuration did not specify a DNS server address.

              • If the phone has a static IP address, verify that the DNS server has been configured.
              • If you are using DHCP, the DHCP server has not provided a DNS server. Check the DHCP server configuration.

              TFTP access error

              TFTP server is pointing to a directory that does not exist.

              • If you are using DHCP, verify that the DHCP server is pointing to the correct TFTP server.
              • If you are using static IP addresses, check the TFTP server configuration.

              TFTP error

              The phone does not recognize an error code provided by the TFTP server.

              Contact the Cisco TAC.

              TFTP file not found

              Streaming Statistics

              A Cisco Unified IP Phone can stream information to and from up to three devices simultaneously. A phone streams information when it is on a a call or running a service that sends or receives audio or data.

              The streaming statistics areas on a phone web page provide information about the streams. Cisco Unified SIP Phone 3905 use only Stream 1.

              To display a Streaming Statistics area, access the web page for the phone as described in Access Web Page for phone and click the Stream 1 hyperlink.

              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

              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
