Table 1. Status Messages on the Cisco IP Phone
Message	Description	Possible Explanation and Action
Could not acquire an IP address from DHCP	The phone has not previously obtained an IP address from a DHCP Server. This can occur when you perform an out of box or factory reset.	Confirm that the DHCP server is available and that an IP address is available for the phone.
TFTP Size Error	The configuration file is too large for file system on the phone.	Power cycle the phone.
ROM 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.
Duplicate IP	Another device is using the IP address that is assigned to the phone.	If the phone has a static IP address, verify that you did not assigned a duplicate IP address. If you are using DHCP, check the DHCP server configuration.
Erasing CTL and ITL files	Erasing CTL or ITL file.	None. This message is informational only.
Error Updating Locale	One or more localization files could not be found in the TFTP Path 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 <Cfg File>	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 does not exist in 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 autoregister. 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.
File Not Found <CTLFile.tlv>	This message displays on the phone when the Cisco Unified Communications Manager cluster is not in secure mode.	No impact; the phone can still register to Cisco Unified Communications Manager.
IP Address Released	The phone is configured to release the IP address.	The phone remains idle until it is power cycled or until you reset the DHCP address.
IPv4 DHCP Timeout	IPv4 DHCP server did not respond.	Network is busy: The errors should resolve themselves when the network load reduces. No network connectivity between the IPv4 DHCP server and the phone: Verify the network connections. IPv4 DHCP server is down: Check configuration of IPv4 DHCP server. Errors persist: Consider assigning a static IPv4 address.
IPv6 DHCP Timeout	IPv6 DHCP server did not respond.	Network is busy - The errors should resolve themselves when the network load reduces. No network connectivity between the IPv6 DHCP server and the phone: Verify the network connections. IPv6 DHCP server is down: Check configuration of IPv6 DHCP server. Errors persist: Consider assigning a static IPv6 address.
IPv4 DNS Timeout	IPv4 DNS server did not respond.	Network is busy: The errors should resolve themselves when the network load reduces. No network connectivity between the IPv4 DNS server and the phone: Verify the network connections. IPv4 DNS server is down: Check configuration of the IPv4 DNS server.
IPv6 DNS Timeout	IPv6 DNS server did not respond.	Network is busy: The errors should resolve themselves when the network load reduces. No network connectivity between the IPv6 DNS server and the phone: Verify the network connections. IPv6 DNS server is down: Check configuration of the IPv6 DNS server.
DNS unknown IPv4 Host	IPv4 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 IPv4 DNS. Consider using IPv4 addresses rather than host names
DNS unknown IPv6 Host	IPv6 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 IPv6 DNS. Consider using IPv6 addresses rather than host names
Load Rejected HC	The application that was downloaded is not compatible with the phone hardware.	Occurs if you attempt to install a version of software on this phone that did not support hardware changes on this phone. Check the load ID that is assigned to the phone (from Cisco Unified Communications Manager, choose Device > Phone). Reenter the load that displays 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 is configured. If you are using DHCP, the DHCP server has not provided a default router. Check the DHCP server configuration.
No IPv4 DNS Server	A name was specified but DHCP or static IP configuration did not specify a IPv4 DNS server address.	If the phone has a static IP address, verify that the IPv4 DNS server is configured. If you are using DHCP, the DHCP server has not provided a IPv4 DNS server. Check the DHCP server configuration.
No IPv6 DNS Server	A name was specified but DHCP or static IP configuration did not specify a IPv6 DNS server address.	If the phone has a static IP address, verify that the IPv6 DNS server is configured. If you are using DHCP, the DHCP server has not provided a IPv6 DNS server. Check the DHCP server configuration.
No Trust List Installed	The CTL file or the ITL file is not installed on the phone.	The trust list is not configured on the Cisco Unified Communications Manager, which does not support security by default. The trust list is not configured. For more information about trust lists, see the documentation for your particular Cisco Unified Communications Manager release.
Phone failed to register. Cert key size is not FIPS compliant.	FIPS requires that the RSA server certificate is 2048 bits or greater.	Update the certificate.
Restart requested by Cisco Unified Communications Manager	The phone is restarting due to a request from Cisco Unified Communications Manager.	Configuration changes were likely made to the phone in Cisco Unified Communications Manager, and Apply Config was pressed so that the changes take effect.
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.
TFTP Error	The phone does not recognize an error code that the TFTP server provided.	Contact Cisco TAC.
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.
Trust List Update Failed	Update of the CTL and ITL files failed.	Phone has CTL and ITL files installed and it failed to update the new CTL and ITL files. Possible reasons for failure: Network failure occurred. TFTP server was down. The new security token that was used to sign CTL file and the TFTP certificate that was used to sign ITL file are introduced, but are not available in the current CTL and ITL files in the phone. Internal phone failure occurred. Possible solutions: Check network connectivity. Check whether the TFTP server is active and functioning normally. If the Transactional Vsam Services (TVS) server is supported on Cisco Unified Communications Manager, check whether the TVS server is active and functioning normally. Verify whether the security token and the TFTP server are valid. Manually delete the CTL and ITL files if all the preceding solutions fail; reset the phone. For more information about trust lists, see the documentation for your particular Cisco Unified Communications Manager release.
Trust List Updated	The CTL file, the ITL file, or both files are updated.	None. This message is informational only. For more information about trust lists, see the documentation for your particular Cisco Unified Communications Manager release.
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 message indicates the name of the configuration file for the phone.

Rcvr Packets	Total number of RTP data packets that the phone has received since data reception started on this connection. Includes packets that were received from different sources if this call is a multicast call. The value displays as 0 if the connection was set to send-only mode.
Rcvr Octets	Total number of payload octets that the device received in RTP data packets since reception started on the connection. Includes packets that were received from different sources if this call is a multicast call. The value displays as 0 if the connection was set to send-only mode.
Cumulative Conceal Ratio	Total number of concealment frames divided by total number of speech frames that were received from the start of the voice stream.
Interval Conceal Ratio	Ratio of concealment frames to speech frames in the preceding 3-second interval of active speech. If voice activity detection (VAD) is in use, a longer interval might be required to accumulate three seconds of active speech.
Max Conceal Ratio	Highest interval concealment ratio from the start of the voice stream.
Conceal Seconds	Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds).
Severely Conceal Seconds	Number of seconds that have more than five percent concealment events (lost frames) from the start of the voice stream.
Latency (see note)	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.
Max Jitter	Maximum value of instantaneous jitter, in milliseconds.
Sender Size	RTP packet size, in milliseconds, for the transmitted stream.
Sender Reports Received (see note)	Number of times RTCP Sender Reports have been received.
Sender Report Time Received (see note)	Most recent time when an RTCP Sender Report was received.
Receiver Size	RTP packet size, in milliseconds, for the received stream.
Receiver Discarded	RTP packets that were received from the network but were discarded from the jitter buffers.
Receiver Reports Received (see note)	Number of times RTCP Receiver Reports have been received.
Receiver Report Time Received (see note)	Most recent time when an RTCP Receiver Report was received.

Note

When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.

Request Information from the Phone in XML

For troubleshooting purposes, you can request information from the phone. The resulting information is in XML format. The following information is available:

CallInfo is call session information for a specific line.
LineInfo is line configuration information for the phone.
ModeInfo is phone mode information.

Before you begin

Web access needs to be enabled to get the information.

The phone must be associated with a user.

Procedure

Step 1

For Call Info, enter the following URL in a browser: http://<phone ip address>/CGI/Java/CallInfo<x>

where

<phone ip address> is the IP address of the phone
<x> is the line number to obtain information about.

The command returns an XML document.

Step 2

For Line Info, enter the following URL in a browser: http://<phone ip address>/CGI/Java/LineInfo

where

<phone ip address> is the IP address of the phone

The command returns an XML document.

Step 3

For Model Info, enter the following URL in a browser: http://<phone ip address>/CGI/Java/ModeInfo

where

<phone ip address> is the IP address of the phone

The command returns an XML document.
