Chapter 9 Troubleshooting and Maintenance
Resolving Startup Problems
To start a service, follow these steps:
Procedure
Step 1 From Cisco Unified Communications Manager Administration, choose Application >
Cisco Unified Communications Manager Serviceability.
Step 2 Choose Tools > Control Center.
Step 3 From the Servers column, choose the primary Cisco Unified Communications Manager server.
The page displays the service names for the server that you chose, the status of the services, and a service
control panel to stop or start a service.
Step 4 If a service has stopped, click the Start button.
The Service Status symbol changes from a square to an arrow.
Creating a New Configuration File
If you continue to have problems with a particular phone that other suggestions in this chapter do not
resolve, the configuration file may be corrupted. To create a new configuration file, follow these steps:
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 Adding Phones to the
Cisco Unified Communications Manager Database, page 2-7 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.
