Features and capabilities


The 8865 Key Expansion Module gives you access to more line and feature keys than come standard with the 8865 IP Phones.

With the module, you can customize additional line or feature keys for telephony features you use frequently. For example, speed dials give you one-button access to the colleagues and staff you collaborate with most often.

The module also supports shared-line appearances between administrative staff, knowledge workers, and managers. These appearances enable a more personal touch, increasing responsiveness in support of inbound callers.

The module supports both Session Line Mode (SLM) and Enhanced Line Mode (ELM) user experiences. ELM support makes 8800 Series IP Phones a good fit for staff who currently have Cisco IP Phone 7900 Series and would like to take advantage of 8800 benefits.

User features:

  • Program 14 physical keys per module, 28 keys with "second page" in software
  • Keys present up to 14 characters when active, enhancing user accuracy in call handling
  • Two graphical, backlit, high-resolution color displays makes viewing easy
  • Get status of available staff with Busy Lamp Field (BLF) support
  • View both voice message and missed call counts on the display

IT benefits:

  • SLM and ELM support help minimize retraining when upgrading to the 8800 Series
  • One-, two-, and three-module configurations expand scalability and extend IP phone investment
  • Power options include Power over Ethernet (POE) and a local power cube
  • The Power Save Plus option reduces power consumption in off-hours

Generally available August 2017. Contact your Cisco representative for further details.
