Refer to the IP Telephony Configuration Guide for detailed instructions about installing the 20XX
IP telephones and to the WLAN IP telephone documentation for detailed instructions about
installing and registering the WLAN handsets.
Feature DNs
The system also uses DNs to define remote access features and Hunt group s . These DNs do not
show up on the System DNs list.
• System Access DNs: For remote access to direct-dial lines, the system requires an Auto DN or
a DISA DN. These two settings are found under the Access codes heading. Refer to the remote
access information in
“Understanding access codes” on page 320 .
• Hunt Group DNs: Hunt Groups are identified by a unique DN for each defined Hunt group.
Refer to Chapter 23, “Configuring Hunt groups,” on page 577 for more information.
Renumbering DNs
Your system auto assigns DNs based on the hardware for digital telephones, or, in the case of IP
telephones, you choose to auto assign DNs when the telephones register to the system. If you need
to change the DN numbers for any reason, there are two ways to do this.
• “Using a wizard to renumber telephone DNs”
• “Change telephone DNs using the Unified Manager”
When you change a DN, the DN record retains the same port number, since the telephone is not
being physically moved. The original DN then assigns to the port vacated by the DN that you
assign as the
new DN. If you filled out the DN/Port record in the Programming Records, remember
to change the entries.
Using a wizard to renumber telephone DNs
If you need to renumber any DNs, you can use the DN Renumber Wizard, which allows you to
renumber a range of DNs.
Follow these steps to use the DN Renumber Wizard to renumber DNs on your system:
1 From the first page of the Unified Manager, click the Wizards button.
2
Enter your system user ID and password, then click Login .
3 Click the DN Renumber button.
4
On the first screen, enter the range of DNs to change, and the DN with which to start
re-numbering.
5
The Summary page displays the information you entered. Review and revise, if necessary.
6 Click the Apply button.
