Implementing features, see also Manager E Whisper/Off Hook Announcement

Definition

The "Whisper/Off Hook Announcement" feature allows stations (station C in the illustration) to monitor an existing call between two stations (stations A and B in the illustration), and to pass on information to one of these stations (A). In other words, the connection is switched in such a way that only station A hears station C, and station B only hears A.

Although there is no connection between station B and station C, user B may be able to hear the muffled tones of what user C is saying because of feedback on station A.

Station C activates this feature by dialing a code. The telephone features a part-programmed key (only the code is programmed on the key, the station number must be suffix-dialed). A new menu item will be incorporated into the Service menu, the Idle/Call menu will remain unchanged.

The option for activating the feature is linked to a new, user-specific class of service. A second class of service can be used to protect station A from Whisper/Off Hook Announcement.

The feature is deactivated by the activating station (station C) or by modifying the features, but NOT through a separate code.

The "Whisper" feature is designed for use in call centers or executive/secretary systems, for example, and enables the user to communicate with one party (A) without the knowledge of the other party (B).

The option for activating the feature is linked to a new user-specific class of service. Station A can block the Whisper feature with a second class of service.

Restrictions

•	If neither of the participants in the original call (station A or B) is a TDM station, the HiPath switching network is not involved at the time of activation and changeover is impossible without briefly interrupting the connection between A and B.

•	Stations A and C must be in the same node.

•	The feature can only be activated by station C from the idle/ready state.

•

Only telephones with a display that can be controlled by the system (optiPoint, OpenScape Personal Edition, OpenStage TDM) can function as destination telephones for Whisper/Off Hook Announcement (station A). Analog telephones cannot function as destination telephones for Whisper/Off Hook Announcement.
CMI is not supported in HiPath 4000.

Dependencies/Restrictions

Just as with the feature Silent Monitoring, Whisper/Off Hook Announcement is only permitted if the call between station A and station B is a simple connection between two stations. The Whisper/Off Hook Announcement feature cannot be used for consultation calls or conference calls.

If the Whisper/Off Hook Announcement feature is active and station A or station B initiates another call-related feature, the Whisper feature will be deactivated. The table below provides further information on interaction with particular features:
