Note Before you install a Cisco Unified IP phone, you must decide how to configure the phone in your network. Then you can install the phone and verify its functionality. For more information, see Chapter 2 "Preparing to Install the Cisco Unified IP Phone on Your Network."


Before You Begin

Before installing the Cisco Unified IP Phone, review the requirements in these sections:

Network Requirements

Cisco Unified Communications Manager Configuration

Network Requirements

For the Cisco Unified IP Phone to successfully operate as a Cisco Unified IP Phone endpoint in your network, your network must meet the following requirements:

Working VoIP network:

VoIP configured on your Cisco routers and gateways

Cisco UnifiedCM installed in your network and configured to handle call processing

IP network that supports DHCP or manual assignment of IP address, gateway, and subnet mask


Note The Cisco Unified IP Phone displays the date and time from Cisco Unified CM. If the Cisco Unified CM server is located in a different time zone than the phones, the phones will not display the correct local time.


Cisco Unified Communications Manager Configuration

The Cisco Unified IP Phone requires Cisco Unified CM to handle call processing. Refer to Cisco Unified Communications Manager Administration Guide or to context-sensitive help in the Cisco Unified Communications Manager application to ensure that Cisco Unified CM is set up properly to manage the phone and to properly route and process calls.

If you plan to use auto-registration, verify that it is enabled and properly configured in Cisco Unified Communications Manager Administration before connecting any Cisco Unified IP Phone to the network. For information about enabling and configuring auto-registration, refer to Cisco Unified Communications Manager Administration Guide. Also, see the "Adding Phones to the Cisco Unified CM Database" section.

You must use Cisco Unified Communications Manager Administration to configure and assign telephony features to the Cisco Unified IP phones. See the "Telephony Features Available for the Cisco Unified IP Phone" section for details.

In Cisco Unified Communications Manager Administration, you can add users to the database, add users to user groups, and associate users to specific phones. In this way, users gain access their Cisco Unified CM User Option page to configure items such as call forwarding, speed dialing, and voice messaging system options. See the "Adding Users to Cisco Unified Communications Manager" section for details.

Understanding the Cisco Unified IP Phones 8941 and 8945 Components

The Cisco Unified IP Phone 8941 and 8945 include these components on the phone or as accessories for the phone:

Network and Access Ports

Handset

Speakerphone

Headset

Network and Access Ports

The back of the Cisco Unified IP Phone 8941 and 8945 includes these ports:

Network port—Labeled network

Access port—Labeled computer

Each port supports 10/100 Mbps half- or full-duplex connections to external devices. Cisco Unified IP Phone 8945 also supports 1000 Mbps full-duplex connections to external devices.You can use either Category 3/5/5e cabling for 10-Mbps connections, but you must use Category 5/5e for 100 or 1000 Mbps connections.

Use the SW network port to connect the phone to the network. You must use a straight-through cable on this port. The phone can also obtain inline power from a switch over this connection. See the "Adding Phones to the Cisco Unified CM Database" section for details.

Use the PC access port to connect a network device, such as a computer, to the phone. You must use a straight-through cable on this port.

Handset

The handset is designed especially for use with a Cisco Unified IP Phone. It includes a light strip that indicates incoming calls and voice messages waiting.

To connect a handset to the Cisco Unified IP Phone, plug the cable into the handset and the Handset port on the back of the phone.

Speakerphone

By default, the speakerphone is enabled on the Cisco Unified IP Phone.

You can disable the speakerphone by using Cisco Unified Communications Manager Administration. To do so, choose Device > Phone and locate the phone you want to modify. In the Phone Configuration window for the phone, check the Disable Speakerphone check box.

Headset

Although Cisco Systems performs internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco Systems does not certify or support products from headset or handset vendors.

Cisco recommends the use of good quality external devices, for example, headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and their proximity to other devices such as cell phones and two-way radios, some audio noise or echo may still occur. An audible hum or buzz may be heard by either the remote party or by both the remote party and the Cisco Unified IP Phone user. Humming or buzzing sounds can be caused by a range of outside sources; for example, electric lights, electric motors, or large PC monitors. See the "Using External Devices" section for more information.


Note In some cases, hum may be reduced or eliminated by using a local power cube or power injector.


These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed means that there is not a single headset solution that is optimal for all environments.

Cisco recommends that customers test headsets in their intended environment to determine performance before making a purchasing decision and deploying en masse.


Note The Cisco Unified IP Phone 8941 and 8945 support wideband headsets.


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 to the party on the far end. Sound quality is subjective and Cisco cannot guarantee the performance of any headsets. However, a variety of headsets from leading headset manufacturers have been reported to perform well with Cisco Unified IP Phones.

For additional information, see the Headsets for Cisco Unified IP Phones and Desktop Clients page on Cisco.com.

Connecting a Headset

To connect a wired headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the phone. Press the Headset button on the phone to place and answer calls using the headset.

You can use the wired 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.

Disabling a Headset

You can disable the headset by using Cisco Unified Communications Manager Administration. If you do so, you also will disable the speakerphone.

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

Using External Devices

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

Cisco recommends the use of good quality external devices 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 headsets that are fully compliant with the EMC Directive [89/336/EC].

Installing the Cisco Unified IP Phone

You must connect the Cisco Unified IP Phone to the network and to a power source before using it. See Figure 3-1 shows the connections for Cisco Unified IP phones 8941and 8945.
