Table 6-1 Status Messages on the Cisco Unified IP Phones 7960G and 7940G 

Message	Description	Possible Explanation and Action
BootP server used	The phone obtained its IP address from a BootP server rather than a DHCP server.	None. This message is informational only.
File auth error	An error occurred when the phone tried to validate the signature of a signed file. This message includes the name of the file that failed.	•The file is corrupted. If the file is a phone configuration file, delete the phone from the Cisco Unified Communications Manager database using Cisco Unified Communications Manager Administration. Then add the phone back to the Cisco Unified Communications Manager database using Cisco Unified Communications Manager Administration. •There is a problem with the CTL file and the key for the server from which files are obtained is bad. In this case, run the CTL client and update the CTL file, making sure that the proper TFTP servers are included in this file.
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 "Adding Phones with Cisco Unified Communications Manager Administration" section on page 2-9 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 configuration of the TFTP server. See the "Network Configuration Menu" section on page 4-4 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 Configuration Menu" section on page 4-4 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 Configuration Menu" section on page 4-4 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 the subdirectories in 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
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 Configuration Menu" section on page 4-4 section 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'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. See the "Firmware Versions Screen" section to verify the phone setting.
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 Configuration Menu" section on page 4-4 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 Configuration Menu" section on page 4-4 section for details. •If you are using DHCP, the DHCP server has not provided a DNS server. Check the DHCP server configuration.
Programming Error	The phone failed during programming.	Attempt to resolve this error by power cycling the phone. If the problem persists, contact Cisco technical support for additional assistance.
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.
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 Configuration Menu" section on page 4-4 for details on assigning a TFTP server.
TFTP file not found	The requested load file (.bin) was not found in the TFTPPath directory.	From Cisco Unified Operating System Administration, make sure that the phone load file is listed in TFTP File Management.
TFTP server not authorized	The specified TFTP server could not be found in the phone's CTL.	•The DHCP server is not configured properly and is not serving the correct TFTP server address. In this case, update the TFTP server configuration to specify the correct TFTP server. •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 Configuration 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.

RxSize	Size of voice packets, in milliseconds, in the receiving voice stream (RTP streaming audio).
RxCnt	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.
TxSize	Size of voice packets, in milliseconds, in the transmitting voice stream.
TxCnt	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.
Avg Jtr	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 Jtr	Maximum jitter observed since the receiving voice stream was opened.
RxDisc	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.
RxLost	Missing RTP packets (lost in transit).
Voice Quality Metrics
MOS LQK	Score that is an objective estimate of the mean opinion score (MOS) for listening quality (LQK) that rates from 5 (excellent) to 1 (bad). This score is based on audible concealment events due to frame loss in the preceding 8-second interval of the voice stream. For more information, see the "Monitoring the Voice Quality of Calls" section on page 8-15. 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 observed for the entire voice stream.
Min MOS LQK	Lowest MOS LQK score observed from start of the voice stream.
Max MOS LQK	Baseline or highest MOS LQK score observed from start of the voice stream. These codecs provide the following maximum MOS LQK score under normal conditions with no frame loss: •G.711 gives 4.5 •G.729 A /AB gives 3.7
MOS LQK Version	Version of the Cisco proprietary algorithm used to calculate MOS LQK scores.
Cmltve Conceal Ratio	Total number of concealment frames divided by total number of speech frames received from start of the voice stream.
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.
