Phone Accessories

The following phone accessories support Cisco IP Phones with Multiplatform Firmware:

You can't use enterprise expansion modules with multiplatform devices. The multiplatform key expansion modules have different SKUs and aren't interchangeable. Use the following SKUs when you order an expansion module for a multiplatform phone:

  • Cisco IP Phone 6851—CP-68KEM-3PCC=

  • Cisco IP Phone 8851, 8861, and 8865—CP-8800-A-KEM-3PC=

  • Cisco IP Phone 8851, 8861, and 8865—CP-8800-V-KEM-3PC=


Key expansion modules are used as overflow for Webex Calling and keys cannot be specifically assigned. If an administrator assigns more monitored lines than the phone can handle, the line status overflows to the key expansion module. For more information, see Cisco IP Phone 6800 Series and Cisco IP Phone 8800 Series Multiplatform Phones.
