Chapter 7 Viewing Security, Device, Model, and Status Information on the Phone
Viewing the Phone Status Menu
Viewing the Current Configuration
You can use the Settings menu and Status menu to determine the name of the
configuration file for the Cisco
Unified Wireless IP Phone 7921G.
To locate the configuration file name, follow these steps:
TFTP server not authorized
The specified TFTP server could
not be found in the phone CTL.
• The DHCP server is not configured
properly and is not providing 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.
