Special Calls/Conversations
Telephoning 163
event that a door call is signalled on multiple SIP system telephones, the
corresponding camera image appears on all telephones during the call
phase. Once the door call is accepted by one of the called subscribers, the
camera image automatically disappears from all other called telephones.
●
Outgoing door call: If you call an entrance intercom, which is equipped
with a door camera, the camera image is not automatically displayed. To
show the camera image, you must press the corresponding function
key.
Switching between images of different cameras
A direct switch between images from different cameras is not possible. If you
would like to switch from a currently displayed camera image to a different
image, you must first hide the camera image being displayed (see page 162).
Then press the function key for the camera you want.
Substitution
You can forward calls for your trunk key to another internal subscriber who
also has a trunk key with this call number.
Calls for this trunk key are now only indicated on your telephone by a visual
signal. On the substitute’s telephone, the calls are indicated by a visual signal
and acoustically, even if the key there has been configured with a different
type of call signalling.
Calls from direct-call keys to your telephone are signalled acoustically even if
you have programmed a substitute (unless you have programmed call
protection for this trunk key). If call protection has been activated, this trunk
key will only indicate calls by means of a visual signal, even if they are made
from a direct-call key.
Switching function on/off
Press the programmed Substitution feature key (see also
page 106).
