Distinctive Features of the Communications System
When you operate an Aastra 673xi / 675xi on the OpenCom 100 / Aastra 800 communications system, some functions deviate 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 functions provided by the communications system are used. The corresponding local
device menus will not appear then.
•The Aastra 673xi / 675xi does not offer call forwarding. This means that in the sim-
plified Options menu the item 1.Call Forward is not available (please refer to The

OpenCom 100 / Aastra 800 communications system (please refer to Call Forwarding starting on page 19).
The Aastra 673xi / 675xi does not save any call numbers in the local caller list nor
does it offer a local phone book. Configure function keys instead to access the
callers list (Caller Lists starting on page 18) and the phone book (please refer to
Phone Book starting on page 19) of the OpenCom 100 / Aastra 800 communications system.
•The Aastra 673xi / 675xi has a separate Web interface. This is blocked by the
