Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE for Cisco Unified Communications Manager 6.0
OL-11953-01
Description
DNS server did not respond.
DNS could not resolve the
name of the TFTP server or
Cisco
Unified Communications
Manager.
Another device is using the IP
address assigned to the phone.
Possible Explanation and Action
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.
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.
If the phone has a static IP address, verify
•
that you have not assigned a duplicate IP
address. See the
"Network Configuration
Menu" section on page 4-7
details.
If you are using DHCP, check the DHCP
•
server configuration.
