Intercom

A CUCM feature providing one-way or two-way speakerphone calls to a designated phone, with a whisper path and auto-answer.

Definition

Intercom lines use dedicated intercom partitions and CSSs separate from regular DNs. The caller's voice is played over the target's speaker (whisper) while the target's microphone stays muted until the recipient presses the line to talk. It is typically used between managers and assistants.

Example

A manager presses the intercom button and speaks to the assistant through her speakerphone.

Exam tip

Intercom DNs use intercom partitions and cannot be reached from normal CSSs.
