Step 3 Add the phone back to the Cisco Unified CallManager database. See the “Adding
Phones to the Cisco Unified CallManager Database” section on page 2-12 for
details.
Step 4 Power cycle the phone.
Note • 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 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.
Registering the Phone with Cisco Unified CallManager
A Cisco Unified IP Phone can register with a Cisco Unified CallManager server
only if the phone has been added to the server or if auto-registration is enabled.
Review the information and procedures in the
“Adding Phones to the
Cisco Unified CallManager Database” section on page 2-12 to ensure that the
phone has been added to the Cisco Unified CallManager database.
To verify that the phone is in the Cisco Unified CallManager database, choose
Device > Phone > Find from Cisco
Unified CallManager Administration to
search for the phone based on its MAC Address. For information about
determining a MAC address, see the
“Determining the MAC Address of a
Cisco Unified IP Phone” section on page 2-19.
