Active room monitoring:
As soon as the ambient noise level near the monitoring phone exceeds the configured
level (noise sensitivity
immediately triggered to an internal or external destination number you have specified
(destination phone).
When the call is answered on the destination phone, a call is set up: one-way (connection
only from the monitoring to the destination phone) or two-way (mutual call connection dur-
ing 1minute in hands-free mode). Provided the call connection is not previously termi-
nated neither on the monitoring nor on the destination phone, the connection will automat-
ically be terminated after 1 minute. The microphone for room monitoring is reactivated
after 1 minute and a call only triggered when the configured level is again exceeded.
When the destination phone is busy, the microphone for room monitoring is reactivated
after 15 seconds. When the destination phone does not answer, the call is terminated and
the microphone for room monitoring is reactivated after 1 minute. A call is only triggered
again when the configured level is again exceeded.
When the monitoring phone receives an internal or external call from another phone as
the destination phone, this call is only visually but not acoustically signalled. You can
answer the call on the monitoring phone. You can also make a call on the monitoring
phone. Once the call has been terminated, the monitoring phone immediately switches
back to monitoring mode. Please note that room monitoring is deactivated as long as the
monitoring phone is called or is in a call connection. Avoid these monitoring gaps by acti-
vating a call forwarding on the monitoring phone. A verification call of the destination
phone is yet possible with call forwarding.
Room monitoring mode:
• Active room monitoring with one-way call connection.
• Active room monitoring with two-way call connection.
• Passive room monitoring
Notes:
• The reliability of the room monitoring depends on the quality of the radio connection.
• Extraneous noises in the monitored room call lead to false calls.
• Therefore no liability can be assumed for failed monitoring calls or for false calls.
Passive room monitoring:
You can also listen into the monitored room using a verification call. Call the monitoring
phone from the destination phone. When the destination number is an external call num-
ber, CLIP may not be suppressed. The monitoring phone answers the call automatically
and without acoustic signalling and sets up a one-way or two-way call connection
depending on the settings. This is possible even if a call forwarding is activated on the
monitoring phone.
