Cisco Unified IP Phone Administration Guide for Cisco Unified Communications Manager 8.6 (SCCP and SIP)
Possible Explanation and Action
If the phone has a static IP address, verify that the
•
DNS server has been configured. See
Configuration Menu, page 4-5
If you are using DHCP, the DHCP server has not
•
provided a DNS server. Check the DHCP server
configuration.
Occurs if the CTL file is not configured on the Cisco
Unified Communications Manager and the Cisco
Unified Communications Manager does not support
security by default.
For more information about the CTL file or ITL file,
see Cisco Unified Communications Manager Security
Guide.
Attempt to resolve this error by power cycling the
phone. If the problem persists, contact Cisco
technical support for additional assistance.

If you are using DHCP, verify that the DHCP
•

assigning a TFTP server.
Contact the Cisco TAC.
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.

•
themselves when the network load reduces.
No network connectivity between the TFTP

server and the phone—Verify the network
connections.

•
TFTP server.
