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. |
CTL and ITL installed |
The CTL and ITL files are installed on the phone. |
None. This message is informational only. Neither the CTL file nor the ITL file was installed previously. |
CTL Installed |
A certificate trust list (CTL) file is installed in the phone. |
None. This message is informational only. The CTL file was not installed previously. |
CTL update failed |
The phone could not update the certificate trust list (CTL) file. |
Problem with the CTL file on the TFTP server. |
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. |
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 the 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 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 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 subdirectories in the TFTP File Management:
|
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.
|
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. |
