Distinctive Features of the Communications System
When you operate an Aastra 673xi / 675xi on the OpenCom 1000 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 1000 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 673xi / 675xi does not offer call forwarding. This means that in the
simplified Options menu the item 1.Call Forward is not available (please refer
to The Options Menu starting on page 38). Use the call forwarding function of
the OpenCom 1000 communications system (please refer to Call Forwarding
starting on page 21).
