Cisco Unified IP Phone Installation

Cisco Unified IP Phone Installation

Phone Installation Overview

This chapter helps you install the Cisco Unified IP Phones 7906G and 7911G on a Cisco Unified Communications 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 Telephony Networks.


Before You Begin

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

Network Requirements

For the Cisco Unified IP Phone 7906G and 7911G to successfully operate as a Cisco Unified IP Phone endpoint in your network, your network must meet these requirements:

  • Working Voice over IP (VoIP) Network
    • VoIP configured on your Cisco routers and gateways
    • Cisco Unified Communications Manager Release 4.x or higher installed in your network and configured to handle call processing

      Note


      The minimum firmware release that must be installed on the phone is 7.2(1).


  • 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 will 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. See the Cisco Unified Communications Manager Administration Guide or 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, see the Cisco Unified Communications Manager Administration Guide.

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

In Cisco Unified Communications Manager Administration, you can add users to the database and associate them with specific phones. In this way, users can access their Cisco Unified CM User Option page to configure items such as Call Forward, Speed Dial, and voice message system options.

Cisco Unified IP Phones 7906G and 7911G Components

The Cisco Unified IP Phones 7906G and 7911G include these components on the phone or as accessories for the phone:

Network and Access Ports

The following ports are available on the Cisco Unified IP Phones 7906G and 7911G:

  • Network port—Labeled 10/100 SW. Use the 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 the Cisco Catalyst switch over this connection. See Cisco Unified IP Phone Power for details.
  • Access port (Cisco Unified IP Phone 7911G only)—Labeled 10/100 PC. Use the access port to connect a network device, such as a computer, to the phone. You must use a straight-through cable on this port.

Each port supports 10/100 Mbps half- or full-duplex connections to external devices. The speed and connection type are set through auto-negotiation. You can use either Category 3 or 5 cabling for 10-Mbps connections, but you must use Category 5 for 100 Mbps connections.

See Cisco Unified IP Phone 7906G Installation and Cisco Unified IP Phone 7911G Installation for the connection ports available on the back of the Cisco Unified IP Phone 7906G and 7911G.

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.

Speaker

The Cisco Unified IP Phone 7906G and 7911G include a speaker that you can use to monitor calls. You can enable either the Monitor mode or Group Listen mode to allow users to listen on the speaker.

The speaker is enabled by default. You can disable the speaker using Cisco Unified Communications Manager Administration.

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.

    Monitor Mode

    Users can only listen to a call on the speaker in Monitor mode. To speak to the other party on the call, users must pick up the handset.

    Monitor mode is enabled by default if the speaker is enabled on Cisco Unified Communications Manager Administration.

    From the phone, users can turn on the Monitor function with the Monitor softkey, and turn off this function with the MonOff softkey or by picking up the handset.

    Group Listen Mode

    The handset and speaker can be active simultaneously in Group Listen mode. One user speaks into the handset with others can listen on the speaker.

    Set Up Group Listen Mode on Cisco Unified Communications Manager

    Group Listen mode is disabled by default.

    The Monitor feature softkeys are not available if Group Listen mode is enabled.

    To enable this mode, you use the Phone Configuration window in Cisco Unified Communications Manager Administration.

    Procedure
      Step 1   From Cisco Unified Communications Manager Administration, choose Device > Phone and locate the phone you want to modify.
      Step 2   In the Phone Configuration window for the phone (Product Specific Configuration section), check the Enable Group Listen check box.

      Group Listen Activation on Phone

      Group Listen softkeys are displayed if Group Listen mode is enabled on Cisco Unified Communications Manager. However, these softkeys cannot be configured using the Cisco Unified Communications Manager softkey template.

      • GListen: Activates Group Listen on the phone. Displayed when Group Listen mode is enabled but not activated on the phone. After Group Listen is activated on the phone (by pressing GListen), users can deactivate it by hanging up the handset or by pressing GLOff.
      • GLOff: Deactivates Group Listen on the phone. Displayed when Group Listen mode is enabled and activated on the phone.

      Note


      The GListen and GLOff softkeys replace the Monitor and MonOff softkeys when Group Listen mode is enabled in Cisco Unified Communications Manager.


      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. See External Device Use 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 in mass quantities.


      Note


      The Cisco Unified IP Phone 7906G and 7911G supports wideband headsets.


      Audio Quality

      Beyond 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 are 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 headset to the Cisco Unified IP Phones, plug it into the RJ-9 Handset port on the back of the phone. Depending on headset manufacturer’s recommendations, an external amplifier may be required. See headset manufacturer's product documentation for details.

      You can use the headset with all of the features on the Cisco Unified IP Phones, including using the Volume button.

      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 Phones to the network and to a power source before using it.


      Note


      Always upgrade the phone to the current firmware image before installation.



      Note


      Before using external devices, read External Device Use for safety and performance information.

          Related Information

          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 IP Phone Security Features. Also, see the Cisco Unified Communications Manager Security Guide.

          Install Locally Significant Certificate

          You can install an 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 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.
          • The phone should have the correct load file. To verify the image, press the Applications Menu button and choose Settings > Model Information.

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

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

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

            You can control access to the Settings Menu using the Settings Access field in the Cisco Unified Communications Manager Administration Phone Configuration window. For more information, see 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 displays in the LSC option field in the Security Configuration menu so that 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 you can press this softkey.)

            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. Refer to error messages generated on the CAPF server and take appropriate actions.

            You can verify that an LSC is installed on the phone by pressing Applications Menu, then choosing Settings > Model Information, and ensuring that the LSC setting shows Installed.
