can only be used by the local stations of that node.
1.9.2.1 General Information
This section provides information on general requirements and helpful tips regarding the possible
networking scenarios.
Restrictions and Dependencies
– For information on how to upgrade an existing HiPath 3000 (including HiPath 5000 RSM),
please refer to the Migration topic.
– For all types of networking, the servers and clients must be in the same time zone.
– OpenScape Business S multi-gateway networks have only been released within a country
(same time zone, same CO access code).
– As a general rule, all OpenScape Business internetworks are configured using wizards.
OpenScape Voice and HiPath 4000 in the internetwork are configured per node in Expert
mode.
– The Presence Manager (DSS server functionality = network-wide display of busy states at
DSS keys + call pickup) is available in OpenScape Business networks.
– SIP-Q trunks with route 16 (last route) are used to configure homogeneous OpenScape
Business systems via the Networking wizard. External SIP trunks (SIP interconnections) are
used for networking HiPath 4000, OpenScape Voice or other communication systems;
configuration is performed in Expert mode.
– Notes to the used Company Attendants (UC Smart):
– The functionality of Company Attendants (UC Smart) and of the voicemail box are node-
specific. In each node, only ONE voicemail system can be used. As a general rule,
different voicemail systems are allowed in an OpenScape Business internetwork.
– If the UC Suite is used as the voicemail system, any other voicemail systems present in the
internetwork must be disabled by the administrator.
