      Table 5 Status Messages on the Cisco Unified SIP Phone 3905

      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 the Cisco Unified Communications Manager 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.

      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 the Access Phone Web Page, and then click the Stream 1 hyperlink.
