Cisco DP-9800-KEM=

Description

The Cisco Desk Phone 9800 Key Expansion Module (KEM) enhances the phone by providing additional extension lines and programmable buttons. These buttons can be configured as line keys, speed-dial buttons, or other supported phone feature buttons.

Core Features:

• Supports 40 lines
• Two pages of 20 buttons each
• Supports 1 KEM and 46 lines (6 lines on phone) for Cisco 9851
• Supports up to 3 KEMs and 130 lines (10 lines on phone) for Cisco 9861
• Supports up to 3 KEMs and 124-128 lines, depending on configuration (4 or 8 lines on phone screen) for Cisco 9871
• When your 9861 and 9871 phones are powered over Ethernet (PoE), you can only connect one KEM to each phone.
  To connect two or three KEMs, use an adapter to power your phone from an electrical outlet.
• The calling system that your phone is registered to restricts the maximum number of SIP lines available on the phone.
  The supported lines in the table above include both SIP lines and feature line keys (PLK).
