in the customer environment. In order to raise the awareness of security risks and to implement
suitable measures to counteract them, a security checklist is provided in the product
documentation. It is urgently recommended that this checklist be discussed with the customer
during the initial setup and that all implemented measures be carefully documented.
The Security Checklist can be found in the SEBA portal under the Portfolio Information.
1.9 Networking OpenScape Business
The communication system enables the networking of OpenScape Business X3/X5/X8,
OpenScape Business S, HiPath 4000 and OpenScape Voice. In a homogeneous OpenScape
Business network, subscribers can now use features such as the presence status, voicemail,
conferencing and much more in exactly the same way as was originally possible with only a
single OpenScape Business communication system.
Note: The release of networking with HiPath 4000 and OpenScape Voice will occur
separately at a later date.
Possible Networks:
– Pure voice network of OpenScape Business X3/X5/X8
– OpenScape Business X3/X5/X8 network (optionally with UC Suite or UC Smart) and
OpenScape Business S (always with UC Suite).
– OpenScape Business X3/X5/X8 with HiPath 4000 (UC functionality in OpenScape Business
only under certain conditions)
– OpenScape Business X3/X5/X8 with OpenScape Voice (without UC functionality in
OpenScape Business)
– Networking with certified third-party applications and external systems via SIP trunks.
Supplemented with a comprehensive set of features in the area of voice networking, medium-size
companies now have access to a solution that offers a rich portfolio of features.
Configuring an IP network is a complex task and should only be performed by experienced
service technicians.
INFO: For all UC Suite-based networking scenarios described here, closed numbering is
assumed. This means that the dial plan of the internal station numbers must be unique.
In a UC Suite-based internetwork without unified communications, both closed and open
numbering can be used.
Consequently, closed numbering should always be selected for any newly created network (with
UC functionality) to allow for future expansion requests by the customer.
A network of OpenScape Business with the following systems is not supported:
– HiPath 3000
– HiPath 5000 RSM
– OpenScape Office MX
– OpenScape Office LX
The migration from HiPath 3000 to OpenScape Business is described in the "Migration" chapter.
