The Cisco CP-BEKEM is a Key Expansion Module designed to physically extend the call-handling and feature capabilities of Cisco 8800 Series IP Phones. This auxiliary unit connects directly to a compatible base phone, adding extra programmable line keys, feature buttons, and a small status display to the user's desktop phone system. It is engineered for professionals who require immediate, single-touch access to a large number of phone lines, speed dials, or telephony features beyond what the standard phone provides, such as executives, administrative assistants, contact center agents, and financial traders. The module effectively transforms a standard IP phone into a more powerful communication hub without requiring a second phone line or more complex console switching.

The expansion module features a layout of additional buttons, typically backlit and with integrated labels, that can be configured through the Cisco Unified Communications Manager (CUCM) administration software. These buttons can be assigned as additional line appearances for handling multiple calls, direct speed dials to important contacts, busy lamp fields (BLF) to monitor the status of colleagues, or quick-access keys for features like call transfer, conferencing, and voicemail. The small monochrome display provides context for the keys, showing labels, directory numbers, or status information, which is crucial for users managing high call volumes or monitoring multiple lines.

Physically, the module is designed to match the aesthetics of the Cisco 8800 series phones, creating a cohesive desktop setup. It connects to the primary IP phone via a dedicated port and cable, drawing power and data directly from the host phone, which simplifies cabling and eliminates the need for an additional network connection or power adapter. By providing tangible, dedicated buttons for critical functions, the CP-BEKEM enhances productivity, reduces the time spent navigating on-screen menus, and minimizes errors in fast-paced environments, making it a valuable productivity accessory for power users within a Cisco Unified Communications ecosystem.
