If the phone receives power from an external power source, unplug the
Ethernet cable from the Network port on the phone, then unplug the power
supply from the DC adaptor port on the phone. Next, reconnect the power
supply and then reconnect the Ethernet cables.
If the phone receives inline power, unplug the cable from the Network port on
the phone and then plug it back in.
When you remove a phone from the Cisco Unified CallManager database, its
configuration file is deleted from the Cisco Unified CallManager TFTP
server. The phone's directory number or numbers remain in the Cisco Unified
CallManager database. They are called "unassigned DNs" and can be used for
other devices. If unassigned DNs are not used by other devices, delete them
from the Cisco Unified CallManager database. You can use the Route Plan
Report to view and delete unassigned reference numbers. Refer to
Cisco Unified CallManager Administration Guide for more information.
Changing the buttons on a phone button template, or assigning a different
phone button template to a phone, may result in directory numbers that are no
longer accessible from the phone. The directory numbers are still assigned to
the phone in the Cisco Unified CallManager database, but there is no button
on the phone with which calls can be answered. These directory numbers
should be removed from the phone and deleted if necessary.
