    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.

    • 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 configuration of the TFTP server. See the Network Setup Menu for details on assigning a TFTP server.

    CFG TFTP Size Error

    The configuration file is too large for 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 configuration of DHCP server.
    • Errors persist: Consider assigning a static IP address. See the Network Setup Menu for details on 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 configuration of DNS server.

    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. See the Network Setup Menu section for details.
    • If you are using DHCP, check the DHCP server configuration.

    Error update locale

    One or more localization files could not be found in the TFTPPath directory or were not valid. The locale was not changed.

    From Cisco Unified Operating System Administration, check that the following files are located within subdirectories in the TFTP File Management:

    • Located in subdirectory with same name as network locale:
      • tones.xml
    • Located in subdirectory with same name as user locale:
      • glyphs.xml
      • dictionary.xml
      • kate.xml

    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. See the Network Setup Menu for details.

    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 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). 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. See the Network Setup Menu section for details.
    • 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. See the Network Setup Menu section for details.
    • 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 configuration of TFTP server. See the Network Setup Menu for details on assigning a TFTP server.

    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 error

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

    Contact the Cisco TAC.

    TFTP server not authorized

    The specified TFTP server could not be found in the phone CTL file.

    • The DHCP server has the wrong configuration file for the TFTP server. In this case, update the TFTP server configuration to specify the correct TFTP server. The CTL file was made and then the TFTP server address changed. In this case, regenerate the CTL file.
    • If the phone is using a static IP address, the phone may be configured with the wrong TFTP server address. In this case, enter the correct TFTP server address in the Network Setup menu on the phone.
    • If the TFTP server address is correct, there may be a problem with the CTL file. In this case, run the CTL client and update the CTL file, making sure that the proper TFTP servers are included in this file.

    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 configuration of TFTP server.

    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.

      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. Call Statistics Fields describes the information displayed on the screen.


      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.

        Type of voice stream received (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law, G.722.

        Sender Codec

        Type of voice stream transmitted (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law, G.722.

        Rcvr Size

        Size of voice packets, in milliseconds, in the receiving voice stream (RTP streaming audio).

        Sender Size

        Size of voice packets, in milliseconds, in the transmitting voice stream.

        Rcvr Packets

        Number of RTP voice packets received since voice stream was opened.

        Note   

        This number is not necessarily identical to the number of RTP voice packets received since the call began because the call might have been placed on hold.

        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.

        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.

        Rcvr Discarded

        Number of RTP packets in the receiving voice stream that have been discarded (bad packets, too late, and so on).

        Note   

        The phone will discard payload type 19 comfort noise packets that are generated by Cisco Gateways, which will increment this counter.

        Rcvr Lost Packets

        Missing RTP packets (lost in transit).

        Voice Quality Metrics

        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

        Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds).

        Severely Conceal Secs

        Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream.

        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.

        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.
