Cisco Unified IP Phones Installation

Cisco Unified IP Phones Installation

Phone Installation Overview

This chapter helps you install the Cisco Unified IP Phones 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 Phones and Your Network.


Before You Begin

Before installing the Cisco Unified IP Phone, review the requirements in this section.

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 these requirements:

  • Working VoIP network:
    • VoIP configured on your Cisco routers and gateways
    • Cisco Unified Communications Manager 4.x and later 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. The Cisco Unified Communications Manager server does not display the local time if it is located in a different time zone than the phones.


Cisco Unified Communications Manager Setup

The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call processing. See 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 before connecting any Cisco Unified IP Phone to the network. For information about enabling and configuring autoregistration, see Cisco Unified Communications Manager Administration Guide.

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

In Cisco Unified Communications Manager, you can add users to the database and associate them with specific phones. In this way, users gain access to web pages that allow them to configure items such as call forward, speed dial, and voice message system options.

Cisco Unified IP Phone Components

The Cisco Unified IP Phones include these components on the phone or as accessories for the phone.

Network and Access Ports

The back of the Cisco Unified IP Phones includes these ports:

  • Network Port
    • Labeled 10/100 SW on the 7962G, 7942G, 7961G, and 7941G
    • Labeled 10/100/1000 SW on the 7961G-GE and 7941G-GE
  • For the Cisco Unified IP Phones 7962G and 7942G, you can use either Category 3/5/5e cabling for 10-Mbps connections, but you must use Category 5 or 5e for 100 Mbps connections.
  • For the Cisco Unified IP Phones 7961G, 7961G-GE, 7941G, and 7941G-GE, you can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 and 1000 Mbps connections.
  • Access Port
    • Labeled 10/100 PC on the 7962G, 7942G, 7961G, and 7941G
    • Labeled 10/100/1000 PC on the 7961G-GE and 7941G-GE

Each port supports 10/100 or 10/100/1000 Mbps half- or full-duplex connections to external devices.

  • For the Cisco Unified IP Phones 7962G and 7942G, you can use either Category 3/5/5e cabling for 10-Mbps connections, but you must use Category 5 or 5e for 100 Mbps connections.
  • For the Cisco Unified IP Phones 7961G, 7961G-GE, 7941G, and 7941G-GE, you can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 and 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 wideband-capable 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 the handset to the Cisco Unified IP Phones 7962G and 7942G, plug the cable into the handset and the Handset port on the back of the phone.

To connect the handset to the Cisco Unified IP Phones 7961G, 7961G-GE, 7941G, and 7941G-GE, remove the hookswitch clip from the cradle area, as shown in the following figure. Then plug the cable into the handset and into the Handset port on the back of the phone.

Figure 1. Removing the Hookswitch Clip



Speakerphone

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

Disable Speakerphone

To disable the speakerphone using Cisco Unified CM Administration, perform the following procedure:

Procedure
    Step 1   Choose Device > Phone and locate the phone you want to modify.
    Step 2   In the Phone Configuration window, check Disable Speakerphone.
    Step 3   Click Apply.

    Headset

    Although Cisco Systems 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.

    We recommend that 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 External Device Use for more information.


    Note


    In some cases, hum can 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.

    We recommend 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 Phones support wideband headsets.


    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

    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.

    See the wireless headset documentation for information about connecting the headset and using the features.

    Disable Headset

    You can disable the headset by using Cisco Unified Communications Manager Administration.

    To disable the headset, perform the following steps:

    Procedure
      Step 1   Choose Device > Phone and locate the phone you want to modify.
      Step 2   In the Phone Configuration window, check the Disable Speakerphone and Headset check box.
      Step 3   Click Apply.

      Wireless Headset

      By default, the Wireless Headset Hookswitch Control option is disabled. You can enable the option in the Cisco Unified Communications Manager Administration application.

      See the wireless headset documentation for information about connecting the headset and using the features.

      Enable Headset Hookswitch Control
      Procedure
        Step 1   Choose Device > Phone and locate the phone you want to modify.
        Step 2   In the Phone Configuration window, select Enable for Headset Hookswitch Control.

        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].


        Install Cisco Unified IP Phones

        You must connect the Cisco Unified IP Phone to the network and to a power source before using it. See Cisco Unified IP Phone Cable Installation for a graphical representation of the connections.


        Note


        Before you install a phone, even if it is new, upgrade the phone to the current firmware image. Before using external devices, read External Device Use for safety and performance information.

              Before You Begin

              To ensure that the handset attaches securely to a wall-mounted phone, remove the handset wall hook from the handset rest, rotate the hook 180 degrees, and reinsert the hook. Turning the hook exposes a lip on which the handset catches when the phone is vertical. For an illustrated procedure, see Installing the Wall Mount Kit for the Cisco Unified IP Phone at:

              http:/​/​www.cisco.com/​en/​US/​products/​hw/​phones/​ps379/​prod_​installation_​guides_​list.html


              Caution


              Use care not to damage wires or pipes located inside the wall when securing screws to wall studs.


              Procedure
                Step 1   Push in the footstand adjustment button.
                Step 2   Adjust the footstand, so it is flat against the back of the phone.
                Step 3   Insert two screws into a wall stud, matching them to the two screw holes on the back of the footstand.

                The keyholes fit standard phone jack mounts.

                Step 4   Hang the phone on the wall.

                Phone Startup Process Verification

                After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by cycling through the following steps.

                1. These buttons flash on and off in sequence:
                  • Headset (only if the handset is off-hook when the phone powers up. Hang up the handset within 3 seconds to have the phone launch its secondary load. To continue with the primary load, leave the handset off-hook.)
                  • Mute
                  • Speaker
                2. Some or all of the line keys flash amber in sequence.

                  Caution


                  If the line keys flash red in sequence after flashing amber, do not power down the phone until the sequence of red flashes completes. This sequence can take several minutes to complete.


                3. Some or all of the line keys flash green. Normally, this sequence takes just a few seconds. However, if the phone’s Flash memory is erased or the phone load is corrupted, the sequence of green flashes will continue while the phone begins a software update procedure. If the phone performs this procedure, the following buttons light to indicate progress:
                  • Headset—Phone is waiting for the network and completing CDP and DHCP configuration. A DHCP server must be available in your network.
                  • Mute—Phone is downloading images from the TFTP server.
                  • Speaker—Phone is writing images to its Flash memory.
                4. The phone screen displays the Cisco Systems, Inc., logo screen.
                5. These messages appear as the phone starts:
                  • Verifying Load (if the phone load does not match the load on the TFTP server). If this message appears, the phone starts up again and repeats step 1 through step 4 above.
                  • Configuring IP
                  • Updating the Trust List
                  • Updating Locale
                  • Configuring Unified CM List
                  • Registering
                6. The phone screen displays:
                  • Current date and time
                  • Primary directory number
                  • Additional directory numbers and speed dial numbers, if configured
                  • Softkeys

                If the phone successfully passes through these stages, it has started up properly. If the phone does not start up properly, see Startup Problems.

                Cisco Unified IP Phone Security

                The security features protect against several threats, including threats to the identity of the phone and to data. These features establish and maintain authenticated communication streams between the phone and the Cisco Unified Communications Manager server, and digitally sign files before they are delivered.

                For more information about the security features, see Cisco Unified Communications Manager Security Guide.

                Install Locally Significant Certificate

                You can initiate the installation of a Locally Significant Certificate (LSC) from the Security Configuration menu on the phone. This menu also lets you update or remove an LSC.

                Before You Begin

                Make sure that the appropriate Cisco Unified Communications Manager and the Certificate Authority Proxy Function (CAPF) security configurations are complete:

                • The CTL file or ITL file should have a CAPF certificate.
                • On Cisco Unified Communications Operating System Administration, verify that the CAPF certificate has been installed.
                • The CAPF is running and configured.

                For more information, see Cisco Unified Communications Manager Security Guide.

                To configure an LSC on the phone manually, perform these steps:

                Procedure
                  Step 1   Obtain the CAPF authentication code that was set when the CAPF was configured.
                  Step 2   From the phone, choose Settings > Security Configuration.
                  Note   

                  You can control access to the Settings Menu by using the Settings Access field in the Cisco Unified Communications Manager Administration Phone Configuration window. For more information, see the Cisco Unified Communications Manager Administration Guide.

                  Step 3   Press **# to unlock settings on the Security Configuration menu. See Unlock and Lock Options for information using locking and unlocking options.
                  Note   

                  If a Settings Menu password has been set up, SIP Phones present an "Enter password" prompt after you enter **#.

                  Step 4   Scroll to LSC and press Update.

                  The phone prompts for an authentication string.

                  Step 5   Enter the authentication code and press Submit.

                  The phone begins to install, update, or remove the LSC, depending on how the CAPF was configured. During the procedure, a series of messages appears in the LSC option field in the Security Configuration menu, so you can monitor progress. When the procedure completes successfully, the phone displays Installed or Not Installed.

                  The LSC install, update, or removal process can take a long time to complete. You can stop the process at any time by pressing Stop from the Security Configuration menu. Settings must be unlocked before pressing Stop

                  When the phone successfully completes the installation procedure, it displays Success If the phone displays Failure the authorization string may be incorrect or the phone may not be enabled for upgrading. See error messages generated on the CAPF server and take appropriate actions.

                  You can verify that an LSC is installed on the phone by choosing Settings > Model Information and ensuring that the LSC setting shows Yes.

                  Step 6   Verify that an LSC is installed on the phone by choosing Settings > Model Information and ensuring that the LSC setting shows Yes.
