Cisco Unified IP Phone Installation

This chapter helps you install the Cisco Unified IP Phone on an IP telephony network.


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 Cisco Unified IP Phone and Your Network


Before You Begin

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

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:

  • VoIP network:
    • VoIP configured on your Cisco routers and gateways
    • Cisco Unified Communications Manager 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 Communications Manager. The time displayed on the phone can differ from the Cisco Unified Communications Manager time by up to 10 seconds. If the Cisco Unified Communications Manager server is located in a different time zone than the phones, the phones do not display the correct local time.

Cisco Unified Communications Manager setup

The Cisco Unified IP Phone requires Cisco Unified Communications Manager 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 Communications Manager is set up properly to manage the phone and to properly route and process calls.

If you plan to use autoregistration, 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 autoregistration, refer to Cisco Unified Communications Manager Administration Guide.

You must use Cisco Unified Communications Manager Administration to configure and assign telephony features to the Cisco Unified IP Phones.

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 to their Cisco Unified Communications Manager User Option page to configure items such as Call Forward, Speed Dial, and voice message system options.

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

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, or 5e cabling for 10Mbps connections, but you must use Category 5 or 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 Cisco Unified IP Phone power 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 Cisco Unified IP Phone uses a handset that is designed especially for the phone. The handset includes a light strip to indicate incoming calls and voice messages waiting.

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

Disable 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.

Procedure
    Step 1   Select Device > Phone.
    Step 2   Select the phone you want to modify.
    Step 3   In the Phone Configuration window for the phone, check the Disable Speakerphone check box.

    Headset

    Although Cisco performs 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.

    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.


    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 the headsets.


    Note


    The Cisco Unified IP Phone 8941 and 8945 supports wideband headsets.


    Related Information

    Audio Quality

    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.

    Headset Connection

      Step 2   Press the Headset button on the phone to place and answer calls using the headset.

      Disable Wired Headset

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

      Procedure
        Step 1   To disable the headset from Cisco Unified Communications Manager Administration, choose Device > Phone and locate the phone that you want to modify.
        Step 2   In the Phone Configuration window (Product Specific Configuration layout portion), select the Disable Speakerphone and Headset check box.

        Bluetooth Wireless Headsets

        The Cisco Unified IP Phone 8945 supports Bluetooth Class 2 technology when the headsets support Bluetooth. Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best performance is in the 3- to 6-foot range (1 to 2 meters). You can pair up to 5 headsets, but only the last one connected is used as the default.


        Note


        The Cisco Unified IP Phone 8941 does not support Bluetooth.


        There can be a potential interference issues. Cisco recommends that you reduce the proximity of other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal objects. If possible, configure other 802.11 devices to use the 802.11a channels.

        For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone, but some barriers, such as walls or doors, and interference from other electronic devices, could affect the connection.

        Hands-Free Profile

        The Cisco Unified IP Phone 8945 supports various Hands-free Profile features that enable you to use hands-free devices (such as Bluetooth wireless headsets) to perform certain tasks without having to handle the phone. For example, instead of pressing Redial on the phone, users can redial a number from their Bluetooth wireless headset according to instructions from the headset manufacturer.

        The following hands-free features apply to Bluetooth wireless headsets used with the Cisco Unified IP Phone 8945:

        • Answer a call
        • End a call
        • Change the headset volume for a call
        • Redial
        • Caller ID
        • Reject
        • Divert
        • Hold and Accept
        • Release and Accept

        Hands-free devices may differ in how features are activated. Device manufacturers may also use different terms when referring to the same feature.

        For more information, see the manufacturer’s documentation.

        Bluetooth Wireless Headset and Cisco Unified IP Phones

        The Cisco Unified IP Phone connects with headsets using a shared key authentication and encryption method. The Cisco Unified IP Phone can be connected with up to five headsets at a time. The last one connected is used as the default. Pairing is typically performed once for each headset.

        After a device is paired, the Bluetooth connection is maintained as long as both devices (phone and headset) are enabled and within range of each other. The connection typically re-establishes itself automatically if either of the devices powers down then powers up. However, some headsets require user action to re-establish the connection.

        The Bluetooth icon indicates whether or not a device is connected.

        When headsets are more than 30 feet (10 meters) away from the Cisco Unified IP Phone, Bluetooth drops the connection after a 15 to 20 second timeout. If the paired headset comes back into range of the Cisco Unified IP Phone and the phone is not connected to another Bluetooth headset, the in-range Bluetooth headset automatically reconnects. For certain phone types that operate in power-save modes, the user can "wake-up" the headset by tapping on the operational button to initiate the reconnect.

        Enable Bluetooth Wireless Headset

        Before you use your Bluetooth Wireless headset, you must enable it.

        Procedure
          Step 1   In Cisco Unified Communications Manager Administration, choose Device > Phone, locate the phone you want to modify, and go to the Phone Configuration window for that phone.
          Step 2   In the Phone Configuration window, select Enable for the Bluetooth setting and Handsfree for the Bluetooth Profiles setting.
          Step 3   Save your changes.

          Add Bluetooth Wireless Headset

          Cisco recommends that users read the headset user guide for more information about pairing and connecting the headsets.

          After the Bluetooth wireless headset is enabled through Cisco Unified Communications Manager Administration, you must add the headset as an accessory to the phone by following these steps:

          Procedure
            Step 1   On the Cisco Unified IP Phone 8945, press Applications and choose Accessories.
            Step 2   Choose Add Bluetooth Accessory.

            The Adding Bluetooth Accessory window appears. A message tells you to make sure your accessory is “discoverable,” which means that the Bluetooth should be powered on and in “discoverable” or “pairing” mode.

            The phone locates the Bluetooth device.

            The Cisco Unified IP Phone automatically tries to pair with the headset using the “0000” PIN. If the headset does not use the "0000" PIN, a message displays to request a PIN so that the Bluetooth device can be paired with the Cisco Unified IP Phone

            Step 3   If the phone prompts for a PIN, enter the correct PIN by referring to the headset user guide.

            After the phone has the correct PIN, the phone tries to connect to the accessory. The phone provides feedback to the user while it tries to connect the accessory. If unable to connect, an error alert appears to let the user know the reason for the failure. There is a timeout of 10 seconds for the phone to try to connect the accessory. If the timer expires without a successful connection, an error alert is displayed.


            Remove Bluetooth Device from Phone

            When you want to remove a Bluetooth device, you delete it from the Accessories menu.

            Procedure
              Step 1   Press Applications .
              Step 2   Select Accessories.
              Step 3   Highlight the device that you want to remove and press Delete.

              Related Bluetooth Documentation

              For information about how to use your Bluetooth wireless headset, see:

              • Cisco Unified IP Phone 8941 and 8945 User Guide for Cisco Unified Communications Manager (SCCP and SIP)
              • User guides provided with your headset

              External device use

              Cisco recommends the use of good quality external devices, such as 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 performs adequately when suitable devices are attached with 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].
