Passive room monitoring

Passive room monitoring allows the destination user to listen into a room using a
verification call. To do so, he calls the monitoring phone on which room monitoring
is activated. The phone automatically answers the call without any acoustic signa-
lling and switches the connection through. This is also the case when call forwar-
ding has been activated on the monitoring phone.
The check call is possible in all three monitoring modes. The connection type
however is different:
• Room monitoring in modes 1 and 3:
 The call connection is one-way.
• Room monitoring in mode 2:
 The call connection is two-way.
During the call connection
As with calls set-up by the monitoring phone in active room monitoring the user
has the possibility of switching back and forth between one-way mode (digit 1)
and two-way mode (digit 2) once the connection has been set up with DTMF suffix
dialling. The switchover is temporary.

Terminating a call connection

There is no time limit to the duration of a verification call, which must be termina-
ted by the user on the destination phone or by the user on the monitoring phone.
Once the call has been cleared down, the monitoring phone switches back to mo-
nitoring mode without delay.

Calls during passive room monitoring

If another internal or external user calls the phone on which passive room monito-
ring is activated (mode 3), the phone signals the call
the call can be answered in the usual way.
Tip:
Passive room monitoring is indicated on the monitoring phone by the
display reading Room monitoring for ...; no exclamation mark is displayed.
Note: The same display is also shown with active room monitoring before
a delay expires. This is due to the fact that the status "active room monito-
ring with deactivated microphone" is equivalent to passive room monito-
ring.
