OpenScape Branch

Enjoy resilient connectivity at your remote offices with our intelligent branch solutions

Your remote offices and branches need to have access to communications at all time. To this end we have developed a range of software-based solutions  for both service providers and cost-conscious enterprises with multiple branch offices.

Whether you are an enterprise with a simple or sophisticated network, or a cloud-based service provider, we have an intelligent branch solution that can meet your needs. OpenScape Branch runs on commercially available servers and contains a wealth of features including:

• SIP Proxy
• Survivability features (local call control)
• SBC (Session Border Controller)
• Firewalls
• Media server

One of the many advantages of OpenScape Branch is that it provides SIP trunking directly from the branch. This removes the need to transport all voice traffic destined for the PSTN back to the data center and provides network redundancy.

Another major advantage is the built-in Media Server, which dramatically reduces the bandwidth requirements to the branch, saving networking costs every month, and providing local tones, announcements and conferencing facilities even in the event of WAN failure.

We have developed OpenScape Branch systems for up to 50, 250, 1,000 or 6,000 users and provide the ability to cluster them for scalability and local redundancy. There are two main configurations of OpenScape Branch available, either in-network (for use in your own trusted IP network) or out-of-network (for use over an open IP connection, for example in cloud, service provider, franchises and for the Internet and non-trusted WAN networks).
