Methods for Adding Phones to Cisco Unified CallManager
Before installing the wireless IP phone, you must choose a method for adding
phones to the Cisco Unified CallManager database. Some methods require
entering the media access control (MAC) address of the phone. Tab le 3-1 provides
an overview of these methods.

Before You Begin
Adding Phones with Auto-Registration
You can use auto-registration to quickly enter phones into the Cisco
Unified CallManager database without first gathering MAC addresses from the
phones.
When auto-registration is enabled, Cisco Unified CallManager automatically
assigns the next available sequential directory number to new phones as they
register with Cisco Unified CallManager during the initial phone startup process.
After registering phones with Cisco Unified CallManager, you can modify
settings, such as the directory numbers and device pools, by using
Cisco Unified CallManager Administration.
Auto-registration is disabled by default in Cisco Unified CallManager. You must
enable and properly configure auto-registration before connecting any
Cisco Unified IP Phone to the network. For information about enabling and
configuring auto-registration, refer to Cisco Unified CallManager Administration
Guide.

Chapter 3 Setting Up the Cisco Unified Wireless IP Phone 7921G
Adding Phones with Auto-Registration and TAPS
You can add a group of phones quickly by using auto-registration and TAPS. First,
use the Bulk Administration Tool (BAT) to add phones to the
Cisco Unified CallManager database with dummy MAC addresses. Then use
TAPS to update MAC addresses and download pre-defined configurations for the
phones.
To implement TAPS, you or the end-users dial a TAPS directory number and
follow voice prompts. When the process is complete, the phone has downloaded
its directory number and other settings. The correct MAC address for the phone
is updated in Cisco Unified CallManager Administration.
You must enable auto-registration in Cisco Unified CallManager Administration
for TAPS to function.

Adding Phones with BAT
To add a group of phones to the Cisco Unified CallManager database, you can use
BAT. This plug-in application for Cisco Unified CallManager enables you to
perform batch operations, including registration, on multiple phones.
To add phones using BAT only (not in conjunction with TAPS), you first must
obtain the appropriate MAC address for each phone.
Determining the MAC Address of a Cisco Unified IP Phone
Before You Begin
When adding phones to the Cisco Unified CallManager database using
Cisco Unified CallManager Administration or using BAT, you must enter the
media access control (MAC) address of the phone. Tab le 3-2 describes how to
determine the MAC address of the wireless IP phone.
Table 3-2 Determining the MAC Address of the Phone
Method For More Information
Choose Settings > Model
Information > MAC Address and
See “Viewing Model Information”
section on page 7-10
look at the MAC Address field.
Remove the battery and look on the
back of the phone.
See the “Installing or Removing the
Phone Battery” section on page 3-11
For detailed instructions about using BAT, refer to Cisco Unified CallManager
Administration Guide and to Bulk Administration Tool Guide for Cisco
Unified CallManager.

Note When using BAT to add Cisco Unified Wireless IP Phones, use the default setting
for the phone load. The phone load name includes symbols (-, _,.) and BAT does
not permit symbols in an entry.

Adding Phones with Cisco Unified CallManager Administration
You can add phones individually to the Cisco Unified CallManager database
using Cisco Unified CallManager Administration. To do so, you first must obtain
the MAC address for each phone. See the “Methods for Adding Phones to Cisco
Unified CallManager” section on page 3-3 for instructions.
After you have collected MAC addresses, choose Device > Add a New Device in
Cisco Unified CallManager Administration to begin.
For additional instructions and conceptual information about
Cisco Unified CallManager, refer to Cisco Unified CallManager Administration
Guide and to Cisco Unified CallManager System Guide.
