Distinctive Features of the Communications System
When you operate an Aastra 6739i on the OpenCom 100 / Aastra 800 communica-
tions system, some functions differ from how they are described in the installation
guide and in the user guide.
This applies especially to functions which are provided locally on the device as well as
via the OpenCom 100 / Aastra 800 communications system. In these cases, the func-
tions provided by the communications system are used. The corresponding local
device menus will not appear then.
•The Aastra 6739i does not execute its own call forwarding. Use the call forwarding
function of the OpenCom 100 / Aastra 800 communications system (please refer
to Call Forwarding starting on page 24).
•The Aastra 6739i does not manage a local caller list nor a local phone book. Con-
figure function keys instead to access the callers list (Call Lists starting on page 17)
and the phone book (please refer to Phone Book starting on page 25) of the
OpenCom 100 / Aastra 800 communications system.
•The Aastra 6739i has a separate Web interface. This is blocked by the
OpenCom 100 / Aastra 800 communications system.

Notes
•The authorisations of your user group determine which calls are recorded on your
call lists. Your system administrator can specify that internal calls, external calls,
calls when busy, and calls from the door be included on your call lists.
•If your internal call number (e.g. “30”) is configured on multiple terminals, you can
view and edit the redial lists for the call number 30 on each of these terminals. An
edited call list is updated on all these terminals.
•The name is displayed instead of the call number in the call lists if the caller is in
the system phone book.
•The call lists also contains calls transferred or forwarded to you from other internal
subscribers.
•When you receive an external call where the caller is displaying a different call
number than the one actually technically being transmitted, 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.
•Door calls are shown either with the call number, or with the name of the
doorbell – depending on the type of door intercom in use.
•If a caller suppresses display of his/her call number, the call is also saved on the
caller list. Multiple calls from an unknown call number are listed as one entry. The
system administrator can, however, during system configuration, determine that
any calls with unknown call numbers will not be included on your call lists.
