Requires phones to be added individually


The following sections describe these methods:

Adding Phones with Auto-Registration

Adding Phones with Auto-Registration and TAPS

Adding Phones with BAT

Adding Phones with Cisco Unified CallManager Administration

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 begins the automatic startup process to obtain a directory number. During auto-registration, Cisco Unified CallManager automatically assigns the next available sequential directory number to new phones as they register with Cisco Unified CallManager.

After registering phones with Cisco Unified CallManager, you can modify any settings, such as the directory numbers, by using Cisco Unified CallManager Administration. Additionally, you can move auto-registered phones to new locations and assign them to different device pools without affecting their directory numbers.

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.

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 make sure that auto-registration is enabled in Cisco Unified CallManager Administration for TAPS to function.

Refer to Bulk Administration Tool User Guide for Cisco Unified CallManager for detailed instructions about BAT and about TAPS.

Adding Phones with BAT

When you must add several phones at the same time 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

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. Table 3-2 describes how to determine the MAC address of the Cisco Unified Wireless IP Phone.

Table 3-2 Determining the MAC Address of the Phone

Method
For More Information

Choose Menu > Network Config > MAC Address and look at the MAC Address field

See Chapter 5 "Configuring Network Profiles on the Cisco Unified Wireless IP Phone 7920"

Using a Headset

Although Cisco Systems performs some internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco does not certify or support products from headset or handset vendors. Because of the inherent environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed, there is not a single "best" solution that is optimal for all environments. Cisco recommends that customers test the headsets that work best in their environment before deploying a large number of units in their network.

In some instances, the mechanics or electronics of various headsets can cause remote parties to hear an echo of their own voice when they speak to Cisco Unified IP Phone users.

Cisco Systems recommends the use of good quality external devices, like headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of these devices and their proximity to other devices such as cell phones and two-way radios, some audio noise may still occur. See the "Using External Devices with Your Cisco Unified IP Phone" section for more information.

The primary reason that support of a headset would be inappropriate for an installation is the potential for an audible hum. This hum can either be heard by the remote party or by both the remote party and the Cisco Unified IP Phone user. Some potential humming or buzzing sounds can be caused by a range of outside sources, for example, electric lights, being near electric motors, large PC monitors. In some cases, a hum experienced by a user may be reduced or eliminated by using a local power cube (CP-PWR-CUBE-3). See the "Safety Information" section for more information.

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound good to the user and the party on the far end. Sound is subjective and Cisco cannot guarantee the performance of any headsets or handsets, but some of the headsets and handsets on the sites listed below have been reported to perform well on Cisco Unified IP Phones.

Nevertheless, it is ultimately still the customer's responsibility to test this equipment in their own environment to determine suitable performance. For information about headsets, see:

http://vxicorp.com/cisco

http://plantronics.com

Connecting a Headset

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the phone.

You can use the headset with all of the features on the Cisco Unified IP Phone, including the Volume and Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the headset microphone.

Configuring the Ring Tone to the Headset

To send the phone ring tone to the headset, follow these steps:


Step 1 Choose Menu > Phone Settings > Ring Tones > Output.

Step 2 Select either Headset or Speaker and press Select.

The output is set to speaker by default.

Step 3 Press Back to return to the Ring Tones menu.


Disabling a Headset

You can disable the headset through the Cisco Unified CallManager Administration application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified CallManager Administration, choose Device > Phone and locate the phone that you want to modify. In the Phone Configuration web page for the phone, check the Disable Speakerphone and Headset check box.

Using External Devices with Your Cisco Unified IP Phone

The following information applies when you use external devices with the Cisco Unified IP Phone:

Cisco recommends the use of good quality external devices (speakers, microphones, and headsets) that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF) signals.

Depending on the quality of these devices and their proximity to other devices such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:

Move the external device away from the source of the RF or AF signals.

Route the external device cables away from the source of the RF or AF signals.

Use shielded cables for the external device, or use cables with a better shield and connector.

Shorten the length of the external device cable.

Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system will perform adequately when suitable devices are attached using good quality cables and connectors.


Caution In European Union countries, use only external speakers, microphones, and headsets that are fully compliant with the EMC Directive [89/336/EC].
