Telephoning
Special Calls/Conversations
59
How many doorbells are available and with which code number procedure these
can be forwarded depends on the entrance intercom that is connected. Please ask
your system administrator which code number procedure you should use.
Call duration
All door calls are automatically terminated after a specific period has expired (pre-
setting is 60 seconds). This ensures that forwarded door calls do not uninten-
tionally lead to continuous calls (e.g. to a voicebox).
Your system administrator can configure the period in the OpenCom 100 from 30
to 300 seconds and will be able to tell you the current value.
3.5.5 Announcements (with and without Intercom)
Announcements can only be made to system terminals. For you to be able to use
this function, the system administrator must set up the corresponding authori-
sation for you. Announcements can be set up on single or multiple system ter-
minals. The “Announcement” function is available in two versions.
■
Announcement with intercom
: the microphone of the terminal called is
switched on and the person you are calling can immediately answer your
announcement. An announcement with intercom can only be conducted to a
single system terminal (not a group of terminals) .
■
Announcement without intercom
: The called subscriber hears a special infor-
mation tone followed by your announcement. In order to answer your
announcement, the subscriber has to take the call just like a normal call (please
refer to the section
on page 60 also).
If you make an announcement to a group of system telephones (e. g. to a hunt
group number on which calls are signalled simultaneously), all subscribers
called hear the announcement at the same time. You hear a signal tone via
your telephone when the (announcement) connection has been made to all
called subscribers. If one of these subscribers replies to the announcement (by
accepting the call), the announcement call to the other system terminals is ter-
minated.
If the called subscriber is a member of a user group for which announcement pro-
tection is active, no announcements are made to that subscriber’s call number.
