External calls from unknown call number
When you receive an external call where the caller is displaying a different call
number than the one actually technically being transmitted (CLIP no screening), a
“?” appears next to the call number on the display. If the call number indicated on
the display is saved to a phone book entry, the name is displayed as usual along
with a question mark.
Call for a virtual call number (Tele Secretary)
Call numbers not assigned to any telephone or user (virtual call numbers) can be
configured on the Aastra 800 / OpenCom 100. The system administrator can divert
a virtual call number to another internal call number, e.g. the call number of your
telephone. This kind of diverted call is signalled on your telephone just like a
normal call.
VIP calls
VIP calls from authorised users are signalled to you even when call protection, call
waiting protection are activated or call forwarding is programmed. You hear the
melody (please refer to the “Melody” section on page 90 also) and see the entry
VIP call
along with the caller’s call number on the display. Accept the call just like a
normal call.
Multiple trunk keys
If your telephone has multiple trunk keys configured on it (please refer to page 42),
the display shows which call number the call is for, e.g.
For:20
.
Calls During a Conversation
While you are making a call, any incoming calls are signalled acoustically as well as
visually on the display (“Call Waiting”). Call waiting protection must be deactivated
for this to happen (see page 104).
You are making a call, hear the call waiting tone and see the text
Call waiting
as well as the name or call number of the subscriber
waiting on the display.
Press the end key to end the current call. The call waiting call is now
signalled to you just like a normal call.
… or
Press softkey
briefly
to accept the call waiting call. Your first call is
placed on hold. You are speaking with the call waiting caller.
