Press the display key.

You are reconnected with the external 

subscriber.

Press the display key.

You are in a three-way conference call 

with the external and the internal sub-

scriber. 
If the internal subscriber who has been 

called ends the call (press end call key 

a), you will be connected with the 

external subscriber. If you press end call 

key 

a, the external call will be trans-

ferred to the internal subscriber. 

If you get an external call while conduct-

ing an internal call, you will hear the call 

waiting tone (short tone). With Calling 

Line Identification, the caller's number or 

name will appear in the display. 

Press the display key.

The internal call is ended. You are con-

nected to the external caller.

Precondition: the external call is waiting 

on the fixed network connection. 

Press the display key.

The call waiting tone is turned off. You 

remain connected with the internal sub-

scriber. The ringer tone can still be heard 

on other registered handsets. 

If the room monitor is activated, a previ-

ously stored destination number is called 

as soon as a set noise level is reached in 

the room. 
You can store an internal or external 

number in your handset as the destination 

number. 
The room monitor call to an external 

number stops after around 90 seconds. 

The room monitor call to an internal 

number (handset) stops after around 

3 minutes (depending on the base 

station). During use as a room monitor, 

all keys are barred except for the end call 

key 

a. The speaker of the handset is 

muted. The end call key can only be used 

to deactivate the handset.
When the room monitor is activated, 

incoming calls to the handset are indi-

cated without a ringer tone and are only 

shown on the screen. The display and 

keypad are not illuminated and advisory 

tones are also turned off.
If you accept an incoming call, the room 

monitor mode is suspended for the dura-

tion of the call, but the function remains 

activated.
If you switch off the handset, the room 

monitor mode is deactivated. You must 

reactivate the function when you switch 

the handset back on. 

You can not reject calls on the VoIP connection.
