Cisco Systems 8.6 manual Creating a New Configuration File

Chapter 9 Troubleshooting and Maintenance

Resolving Startup Problems

Note A service must be activated before it can be started or stopped. To activate a service, choose Tools > Service Activation.

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 2-8for 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. See
	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 Adding Phones to the Cisco Unified Communications Manager Database, page 2-8to 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 Determining the MAC Address for a Cisco Unified IP Phones, page 2-13.
