BootP server used

The phone obtained its IP address from a BootP server rather than a DHCP server.

None. This message is informational only.

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 CallManager database. If the phone has not been added to the Cisco Unified CallManager database, the TFTP server generates a CFG File Not Found response.

Phone is not registered with Cisco Unified CallManager.

You must manually add the phone to Cisco Unified CallManager if you are not allowing phones to auto-register. See the "Adding Phones with Cisco Unified CallManager Administration" section 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 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.

CTL Installed

A certificate trust list (CTL) file is installed in the phone.

None. This message is informational only.

For more information about the CTL file, refer to the Cisco Unified CallManager Security Guide.

CTL update failed

The phone could not update its certificate trust list (CTL) file.

Problem with the CTL file on the TFTP server.

For more information, refer to the Cisco Unified CallManager Security Guide.

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 for details on assigning a static IP address.

Dialplan Parsing Error

The phone could not parse the dialplan XML file properly.

Problem with the TFTP downloaded dialplan XML file.

For more information refer to the Cisco Unified CallManager Administration Guide.

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 CallManager.

Verify that the host names of the TFTP server or Cisco Unified CallManager 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 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.

Check that the following files are located within subdirectories in the TFTPPath directory:

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

dictionary.xml

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 CallManager database using Cisco Unified CallManager Administration. Then add the phone back to the Cisco Unified CallManager database using Cisco Unified CallManager 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.

File not found

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

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 Configuration Menu" section for details.

Load auth failed

The phone could not load a configuration file.

The configuration file that the phone received from the server identified in this message is corrupt. Make sure that a good version of the configuration file exists on that server.

Load auth failed

A signed phone load file has been modified or renamed.

Make sure that the phone load file that the phone is downloading has not been altered or renamed.

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 CallManager, 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 CallManager, choose Device > Phone). Re-enter the load displayed on the phone. See the "Firmware Versions Screen" section to verify the phone setting.

Load Server is invalid

Indicates an invalid TFTP server IP address or name in the Load Server option.

The Load Server setting is not valid. The Load Server specifies a TFTP server IP address or name from which the phone firmware can be retrieved for upgrades on the phones.

Check the Load Server entry (from Cisco Unified CallManager Administration choose Device > 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 Configuration Menu" section 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 section for details.

If you are using DHCP, the DHCP server has not provided a DNS server. Check the DHCP server configuration.

No CTL installed

A certificate trust list (CTL) file is not installed in the phone.

Occurs if security is not configured or, if security is configured, because the CTL file does not exist on the TFTP server.

For more information, refer to Cisco Unified CallManager Security Guide.

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.

Item
Description

RxType

Type of voice stream received (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law, or Lin16k.

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.

TxType

Type of voice stream transmitted (RTP streaming audio from codec): G.729, G.711 u-law, G.711 A-law, or Lin16k.

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.

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.

Cumulative 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.
