Possible explanation and action
Network is bus: 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.

the TFTP server are valid.
