Chapter

Resolving Startup Problems

Procedure

Step 1

From Cisco Unified Communications Manager, choose

Device > Phone > Find

to locate the phone

experiencing problems.

Step 2

Choose

Delete

to remove the phone from the Cisco Unified Communications Manager database.

Step 3

Add the phone back to the Cisco Unified Communications Manager database. See the

“Adding Phones

to the Cisco Unified CM Database” section on page 2-8

for details.

Step 4

Power cycle the phone.

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 and if there are sufficient number

of unit licenses. Review the information and procedures in the

“Adding Phones to the Cisco Unified CM

Database” section on page 2-8

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 for a Cisco Unified IP Phone” section on page 2-13

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 9-4

for assistance.

For more information on licensing go to the

Licensing

section in the

Cisco Unified Communications

Manager Features and Services Guide.
