Summary
Phone is resetting
Time on phone is incorrect
Phone firmware downgrades
Explanation
The phone resets when it loses contact with the
Cisco Unified Communications Manager software. This lost connection
can be due to any network connectivity disruption, including access point
problems, switch outages, and switch reboots.
See Cisco Unified Wireless IP Phone Resets Unexpectedly, on page
Sometimes the time or date on the phone is incorrect. The Cisco Unified
Wireless IP Phone gets its time and date when it registers with
Cisco Unified Communications Manager. Power cycle the phone to reset
the time or date.
The time shows in either 12 hour or 24 hour format.
After applying a Cisco Unified Communications Manager upgrade or
patch, that is older than the current Cisco Unified Wireless IP Phone
firmware, the phones could automatically downgrade to the load contained
in the patch. Check the Cisco Unified Wireless IP Phone default image in
the TFTP folder to fix this problem.
