Telephoning
74
Normal call
When you are called, the caller’s call number is displayed (if transmitted). If this call
number is also recorded in your phone book, you will see the person’s name instead.
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. Note: Display of the “?” can be deactivated by the system administrator.
Call for a virtual call number (Tele Secretary)
Call numbers not assigned to any telephone or user (virtual call numbers) can be con-
figured 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 tele-
phone. 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 110 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 55),
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 vis-
ually on the display (“Call Waiting”). Call waiting protection must be deactivated for
this to happen (see page 124).
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.
