Note
•
When you remove a phone from the Cisco Unified Communications Manager
database, its configuration file is deleted from the
Cisco Unified Communications Manager TFTP server. The phone’s directory
number or numbers remain in the Cisco Unified Communications Manager
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 Communications Manager database. You can use the Route
Plan Report to view and delete unassigned reference numbers. Refer to
Cisco Unified Communications Manager 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 Communications Manager 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 Communications Manager
A Cisco Unified IP Phone can register with a Cisco Unified Communications
Manager 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 Communications Manager Database”
section on page 2-12
to ensure that the phone has been added to the
Cisco Unified Communications Manager database.
To verify that the phone is in the Cisco Unified Communications Manager
database, choose
Device > Phone > Find
from Cisco Unified Communications
Manager 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
.
If the phone is already in the Cisco Unified Communications Manager database,
its configuration file may be damaged. See the
“Creating a New Configuration
File” section on page 9-7
for assistance.
