9. 6. 26 Room monitoring (Baby surveillance)
This feature is designed specifically for monitoring infants. Acordless system phone
(Office 135, Aastra 600d) is switched to a special monitoring mode and coupled
with an internal or an external destination number.
If noise levels in the area surrounding monitoring phone A exceed a specific value,
a call is automatically triggered to the configured destination B. When the destina-
tion user answers the call, the (one-way or two-way) connection is switched
through. This is referred to as active room monitoring.
It is also possible to make a check call to the monitoring phone A. Without the call
being signalled acoustically, A automatically answers the call and switches a (one-
way or two-way) call connection through. This is referred to as passive room moni-
toring.
