Chapter 4: Understanding OpenScape
Video Use Cases
This chapter illustrates several typical use cases you can set up for interdomain video, location and
identity assurance (LIA), and virtual multipoint control units (MCUs).
Understanding Interdomain Video Solutions
The Siemens OpenScape® Video solution provides SBC-based interdomain video, VPN-based
interdomain video, and gateway-based interdomain video. Each of these solutions is explained next.
Session Border Controller (SBC)-Based Interdomain Video
In a typical SBC use case, an organization with a video room system wants to connect one or more
participants in separate locations to their private domain. For example, an organization is holding a
conference and wants to add a conference participant located outside of the organization’s private

network address translation (NAT) and connects the two parties, as shown in the following figure.
