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 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 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 Cisco Unified Communications Manager 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 Cisco Unified Communications Manager 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.
Disabled	802.1X Authentication is disabled on the phone.	You can enable 802.1X authentication using the Settings > Security Configuration > 802.1X Authentication option on the phone. For more information, see the "802.1X Authentication and Status" section.
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 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
Failed	The phone attempted an 802.1X transaction but authentication failed.	Authentication typically fails because of one of the following: •No shared secret is configured in the phone or authentication server •The shared secret configured in the phone and the authentication server do not match •Phone has not been configured in the authentication server
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.
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 section for details.
Load Auth Failed	The phone could not load a configuration file.	Check that: •A good version of the configuration file exists on the applicable server. •The phone load file being downloaded has not been altered or renamed. •Phone load type is compatible. For example, you cannot place a DEV load configuration file on a REL-signed phone.
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.
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 Communications Manager Administration choose Device > Phone).
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 Communications Manager Security Guide.
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.
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.
Successful - MD5	The phone attempted an 802.1X transaction and authentication achieved.	The phone achieved 802.1X authentication.
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 for details on assigning a TFTP server.
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 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 server 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.
Timed Out	Supplicant attempted 802.1X transaction but timed out to due the absence of an authenticator.	Authentication typically times out if 802.1X authentication 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

The Call Statistics screen displays counters statistics and voice quality metrics in these ways:

•During call—You can view streaming statistics for an active call

•After the call—You can view the call information captured during the last 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 "Monitoring the Cisco Unified IP Phone Remotely."

---

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 last voice stream, take either of these actions:

•If the phone is registered with Cisco Unified Communications Manager, press the Application Menu button, then choose Settings > Status > Call Statistics.
