Enable Autoregistration for Phone
The Cisco IP Phone requires Cisco Unified Communications Manager to handle call processing. See the Cisco
Unified Communications Manager Administration Guide or the context-sensitive help in the Cisco Unified
Communications Manager Administration to ensure that Cisco Unified Communications Manager is set up
properly to manage the phone and to properly route and process calls.
Before you install the Cisco IP Phone, you must choose a method for adding phones to the Cisco Unified
Communications Manager database.
By enabling autoregistration before you install the phones, you can:
• Add phones without first gathering MAC addresses from the phones.
• Automatically add a Cisco IP Phone to the Cisco Unified Communications Manager database when you
• Quickly enter phones into the Cisco Unified Communications Manager database and modify any settings,
• Move autoregistered phones to new locations and assign them to different device pools without affecting
Cisco recommends that you use autoregistration to add fewer than 100 phones to your network. To add more
than 100 phones to your network, use the Bulk Administration Tool (BAT).
Autoregistration is disabled by default. In some cases, you might not want to use autoregistration; for example,
if you want to assign a specific directory number to the phone, or if you want to use a secure connection with
Cisco Unified Communications Manager as described in Cisco Unified Communications Manager Security
Guide. For information about enabling autoregistration, see the "Enabling Autoregistration" section in the
Cisco Unified Communications Manager Administration Guide. When you configure the cluster for mixed
mode through the Cisco CTL client, autoregistration is automatically disabled. When you configure the cluster
for nonsecure mode through the Cisco CTL client, autoregistration is not enabled automatically.
You can add phones with autoregistration and TAPS, the Tool for AutoRegistered Phones Support, without
first gathering MAC addresses from phones.
TAPS works with the Bulk Administration Tool (BAT) to update a batch of phones that were already added
to the Cisco Unified Communications Manager database with dummy MAC addresses. Use TAPS to update
MAC addresses and to download predefined configurations for phones.
Cisco recommends that you use autoregistration and TAPS to add fewer than 100 phones to your network.
To add more than 100 phones to your network, use the Bulk Administration Tool (BAT).
To implement TAPS, you or the end user dials a TAPS directory number and follows voice prompts. After
the process is complete, the phone contains the directory number and other settings, and the phone is updated
in Cisco Unified Communications Manager Administration with the correct MAC address.
