Silent Monitoring 
 
Implementing features, see also Manager E Silent Monitoring

Definition  
An authorized user can monitor a call in progress at any internal station without the other party's knowledge.
Silent Monitoring is only possible if the station to be monitored is engaged in a call. The monitored connection is released as soon as one of the stations in the connection is put on hold, transferred or the call is ended. The monitored connection can only be resumed when the station to be monitored is again engaged in a call.
For V1.2 and later, it is possible for all stations in the system to use the Silent Monitoring capability, rather than just one station. Set the appropriate flags for each authorized station.
This feature can not be used with IP phones but with all other types of phones.
If the user who uses the override feature has an IP phone, or if busy override is to be used for a call made with an IP phone, silent monitoring is not possible.
The microphone is automatically muted if the overriding station is an optiPoint or OpenStage terminal. This feature is not available when using a mobile telephone (CMI) because in this case the system does not support automatic microphone muting.
The microphone is automatically muted if the overriding station is an optiPoint or OpenStage telephone. This feature is not available to analog devices and mobile telephones (CMI) because the system does not support automatic microphone mute in such cases.

Silent Monitoring  
To enable the use of features at a station, both the station flag "silent monitoring" and the flag "override class of service on" must be activated. (Feature cannot be used with CSTA monitoring.)  
Silent monitoring  
The call can be overridden only using code *944 + station number (not from a menu).  
Signaling  
The call is not signaled at the overridden station (no display, no alerting tone, no sound).  
Conference  
Silent Monitoring limits the maximum number of conferences. Maximum number of conferences possible in system = maximum number of simultaneous Silent Monitoring stations.
