Cisco Unified IP Phone Status
Possible explanation and action
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.
Contact the Cisco TAC.
• The DHCP server has the wrong
configuration file for the TFTP server. In this
case, update the TFTP server configuration
to specify the correct TFTP server. The CTL
file was made and then the TFTP server
address changed. In this case, regenerate the
CTL file.
• 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
Setup 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.
• 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.
Authentication typically times out if 802.1X is not
configured on the switch.
Make sure that the phone load file has the correct
name.
