Intercom Call (ICM Call)
A non-blocking ICM is available to all Stations in the System. Users may place an Intercom call
to other Stations in the System by dialing applicable digits as defined in the System Numbering
Plan.
CONDITIONS
- Intercom Dial tone will time-out if action is not taken within Dial-Tone Time or if the
time between digits exceeds the Inter-digit Timer (Error tone is presented when
time-out occurs).
- ICM Dial tone is removed after dialing the first digit.
- If the Called Station is Busy, Intercom Busy tone is provided for the Busy Tone time (7
seconds), then the Error tone is sent by the System; the caller may disconnect or
activate a feature such as Message Wait/Callback prior to the time-out.
- For Digital Phone users, consecutive Intercom calls can be placed without the need to
regain ICM dial tone between calls (no need to hang-up); the user simply presses
another {DSS} button.
- An Intercom call to a Station in the Tone or Voice Announce mode (T or P Intercom
Signaling Mode) is not considered answered unless the Called User lifts the handset
or presses the [SPEAKER] button (goes off-hook).
