An observer or a route-to number vector command can activate Service Observing in a No Talk mode. Communication Manager does not reserve a time slot for the talk path as the observer uses the No Talk mode when the observer wants to only listen to calls. This observing mode reduces unnecessary time slot usage. You can use the time slots for other purpose such as simultaneous call recording sessions.

If you use the No Talk mode, Communication Manager does not allow the observer to select the Listen/Talk mode because Communication Manager reserves no time slot for the talk path.

For call recording applications, use the No Talk mode for more than one simultaneous recording session.

To use the No Talk mode, you must assign a dial code in the Service Observing No Talk Access Code field on the Feature Access Code (FAC) screen. Observers must type the No Talk Feature Access Code (FAC) to activate an observing session for call recording.
