Key Expansion Modules

Cisco IP Phone Key Expansion Module Setup Overview

Key expansion modules add extra line appearances, speed dials, or programmable buttons to the phone. The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons. But Simplified dialing is not supported on expansion modules.


Caution

The slots in the side of the phone are designed only for use with the spine connectors on the key expansion module. Insertion of other objects permanently damages the phone.

There are 3 expansion modules available:

  • Cisco IP Phone 8800 Key Expansion Module—Single LCD screen module, 18 line keys, 2 pages, configure with one or two column displays.

  • Cisco IP Phone 8851/8861 Key Expansion Module—Dual LCD screen module for audio phones, 14 line keys, 2 pages, configure with one-column display only. If you use Enhanced line mode, and you receive a call on a key expansion line, then a Call Alert displays on the phone, and the Caller ID displays on the expansion module line.

  • Cisco IP Phone 8865 Key Expansion Module—Dual LCD screen module for video phones, 14 line keys, 2 pages, configure with one-column display only. If you receive a call on a key expansion line, then a Call Alert displays on the phone, and the Caller ID displays on the expansion module line.

The Cisco IP Phone 8851/8861 Key Expansion Module and the Cisco IP Phone 8865 Key Expansion Module require firmware release 12.0(1) or later, and Cisco Unified Communications Manager 10.5(2) or later to function. Enhanced line mode (ELM) is supported only on the Cisco IP Phone 8851/8861 Key Expansion Module and the Cisco IP Phone 8865 Key Expansion Module. ELM is not supported on the single LCD expansion modules.

You can use more than one expansion module per phone. The Cisco IP Phone 8851 and 8851NR support up to 2 modules. The Cisco IP Phone 8861, 8865, and 8865NR support up to 3 modules. But each module must be the same type. This means that you cannot mix audio expansion modules with video expansion modules. You also cannot use a video expansion module on an audio phone or an audio expansion module on a video phone.

Most calling features are supported on your expansion module, and they are configured by your administrator from the Cisco Unified Communications Manager. If a feature is available on the Self Care Portal, then you can add the feature to your expansion module.

When adding features to your expansion module, remember that each line button supports only one feature. You cannot add more features than the number of programmable line keys on your expansion module.

Also note the line mode when working with a key expansion module. In Session line mode, the first line key on the expansion module is line 6 of the phone template. In Enhanced line mode, it is line 11 of the phone template. Only the first 25 characters are displayed on a line.

Page buttons—2 buttons. The button for page 1 is labeled as 1 and the button for page 2 is labeled as 2. The lights in each button indicate the state of the page as follows:

  • Green steady—Page is in view.

  • Light off—Page is not in view.

  • Amber steady—Page is not in view with one or more alerting calls on the page.

Column Mode for the Cisco IP Phone 8800 Key Expansion Module

If you are using the Cisco IP Phone 8800 Key Expansion Module, you can set it up in one-column mode or two-column mode. Set your mode from the Product Specific Configuration area of your Cisco Unified Communications Manager Administration. Two-column mode is the default on the Cisco IP Phone 8800 Key Expansion Module.

The Cisco IP Phone 8851/8861 Key Expansion Module and the Cisco IP Phone 8865 Key Expansion Module do not support two-column mode.


Note

If the label is longer than the display space in both one- and two-column mode, the text contains an ellipsis (…).

One-Column Mode

In one-column mode, each row in the display corresponds to one line accessed by either the left or right-side buttons. In this configuration, the key expansion module displays 9 lines on page 1, and 9 lines on page 2.

Figure 4. A Cisco IP Phone 8800 Key Expansion Module in One Column Mode

Two-Column Mode

In two-column mode, each of the buttons on the left and right of the screen is assigned to different lines. In this configuration, the key expansion module displays 18 lines on page 1, and 18 lines on page 2.

Key Expansion Module Configuration on Cisco Unified Communications Manager

Key expansion modules are supported by most versions of Cisco Unified Communications Manager.

Set up the Key Expansion Module in Cisco Unified Communications Manager

Expansion modules are enabled from the Expansion Module Information area of the Phone Configuration page on Cisco Unified Communications Manager. If you configure the expansion module incorrectly, an error message displays on the phone. You cannot configure the phone for a dual LCD module and then install a single LCD module. But your choice of expansion module is not permanent. You can configure another module if your needs change.

Before you begin

As a best practice, enable power negotiation on both the switch and the phone. This ensures that the expansion module powers up.

Procedure

Step 1

In Cisco Unified Communications Manager Administration, choose Device > Phone.

The Find and List Phones window appears. You can search for one or more phones that you want to configure for the Cisco IP Phone 8800 Key Expansion Module.

Step 2

Select and enter your search criteria and click Find.

The Find and List Phones window appears with a list of phones that match your search criteria.

Step 3

Click the phone that you want to configure for the Cisco IP Phone 8800 Key Expansion Module. The Phone Configuration window appears.

Step 4

If you have an expansion module with a single LCD screen, scroll down to the Product Specific Configuration area. Enable the One Column Display for KEM field for one-column mode, or disable the field for two-column mode.

Step 5

Scroll down to the Expansion Module Information section. Select the appropriate expansion module for the Module 1 field.

Depending upon your phone, your choices may include:

  • CP-8800-Video 28 Button Key Expansion Module
  • CP-8800-Audio 28 Button Key Expansion Module
  • BEKEM 36-Button Line Expansion Module
Step 6

(Optional) Depending upon your phone model, you can add extra expansion modules. Repeat the previous step for Module 2, and Module 3.
Step 7

Click Save.

Step 8

Select Apply Config.

Step 9

Restart the phone.

Custom Background Images

You can customize a Cisco IP phone with a background image or wallpaper. Customized wallpapers are a popular way to display corporate logos or images and many organizations use them to make their phones stand out.

As of Firmware Release 12.7(1), customized wallpaper is supported on both phones and key expansion modules. But you need one image for the phone and one image for the expansion module.

The phone analyzes the color of your wallpaper and changes the color of your font and icons so they can be read. If your wallpaper is dark, the phone changes the fonts and icons to white. If your wallpaper is light, the phone displays the fonts and icons as black.

But it is best to choose a simple image such as a solid color or pattern for your background. Also you should avoid high contrast images.

You add customized wallpaper in one of two ways:

  • Using the List file

  • Using a Common Phone Profile

If you want the user to be able to select your image from various wallpapers available on the phone, then modify the List file. But if you want to push the image to the phone, then create or modify an existing Common Phone Profile.

Regardless of your approach, note the following:
  • Your images must be in PNG format and the full sized image must be within the following dimensions:

    • Thumbnail images—139 pixels (width) by 109 pixels (height)

    • Cisco IP Phone 8800 Series—800 pixels by 480 pixels

    • Cisco IP Phone 8851 and 8861 Key Expansion Module with a dual LCD screen—320 by 480 pixels

    • Cisco IP Phone 8865 Key Expansion Module with a dual LCD screen—320 by 480 pixels

    • Cisco IP Phone 8800 Key Expansion Module with a single LCD screen—272 by 480 pixels

  • Upload the images, the thumbnails, and List file to your TFTP server. The directory is:

    • Cisco IP Phone 8800 Series—Desktops/800x480x24

    • Cisco IP Phone 8851/8861 Key Expansion Module with a dual LCD screen—Desktops/320x480x24

    • Cisco IP Phone 8865 Key Expansion Module with a dual LCD screen—Desktops/320x480x24

    • Cisco IP Phone 8800 Key Expansion Module with a single LCD screen—Desktops/272x480x24

    After the upload is done, you restart the TFTP server .

  • If you modify your Common Phone Profile, then add the new image to the Background Image field in the format mylogo.png. If you don't want the user selecting their own wallpaper, then uncheck Enable End User Access to Phone Background Image Setting. Save and apply the phone profile. Restart the phones so your changes take effect.

For more information on customizing wallpaper, refer to the following documentation:
