Create New Phone Configuration File; Identify 802.1X Authentication Problems - Cisco 7821 Administration Manual

Create New Phone Configuration File

Note • When you remove a phone from the Cisco Unified Communications Manager database, the
configuration file is deleted from the Cisco Unified Communications Manager TFTP server. The
phone 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 these DNs from the Cisco Unified Communications Manager database. You
can use the Route Plan Report to view and delete unassigned reference numbers. See the 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 the phone has no button on the phone with which calls can be answered. These directory numbers
should be removed from the phone and deleted if necessary.
To create a new configuration file, follow these steps:
Procedure
Step 1 From Cisco Unified Communications Manager, choose Device > Phone and click Find to locate the phone
that is experiencing problems.
Step 2 Choose Delete to remove the phone from the Cisco Unified Communications Manager database.
