Possible Explanation and Action
Contact Cisco TAC.
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.
Phone has CTL and ITL files installed and
it failed to update the new CTL and ITL
files.
Possible reasons for failure:
• Network failure occurred.
• TFTP server was down.
• The new security token that was used
to sign CTL file and the TFTP
certificate that was used to sign ITL
file are introduced, but are not
available in the current CTL and ITL
files in the phone.
• Internal phone failure occurred.
Possible solutions:
• Check network connectivity.
• Check whether the TFTP server is
active and functioning normally.
• If the Transactional Vsam Services
(TVS) server is supported on Cisco
Unified Communications Manager,
check whether the TVS server is active
and functioning normally.
• Verify whether the security token and
the TFTP server are valid.
Manually delete the CTL and ITL files if
all the preceding solutions fail; reset the
phone.
