Making Calls
60
Door call forwarding
You can forward calls signalled by the doorbell to another (internal or external) call
number (so-called “pharmacy line”). This is done using the
Call forwarding
menu
(see page 71).
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 unintentionally
lead to continuous calls (e.g. to a mailbox).
Your system administrator can configure in the OpenCom 100 / Aastra 800 a period
between 30 and 300 seconds and will be able to tell you the current value.
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 authorisation for
you. Announcements can be set up on single or multiple system terminals. The
“Announcement” function is available in two versions.
•
Announcement with intercom
: the microphone of the terminal called is
switched on (hands-free mode) and the person you are calling can immediately
answer your announcement. An announcement with intercom can only be con-
ducted 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 Responding to an announcement on page 61 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 tele-
phone when the (announcement) connection has been made to all called sub-
scribers. If one of these subscribers replies to the announcement (by accepting the
call), the announcement call to the other system terminals is terminated.
The system administrator has to extend the corresponding authorisation for your user
group for you to be able to use the function. If a subscriber being called has activated
announcement protection or intercom protection, announcements to that sub-
scriber’s call number will not be carried out.
