Gateways for Large Systems

Keep your local branches connected at all times with our gateway and intelligent branch solutions

Branches are groups of users, frequently with important interdependent functions, often dedicated to providing the local sales and service interfaces to customers. They are your local presence for customers and clearly need communications which are just as good as in headquarters, perhaps better.

Moreover they must still operate if they become disconnected from HQ (for example because of WAN failures). They cannot close their doors to their customers and therefore they need at least basic call-control functions, preferably more sophisticated functions normally provided by the HQ operations. They also need connections via a gateway to the PSTN (or equivalent) to enable outside communications.

In addition your branches may also have requirements for older analog devices, such as fax machines, elevator phones and door-phones. And on the network side they must include security and call admission-control, and support Voice, UC, and possibly Video too.

Gateways for OpenScape Voice

To help your branches stay connected we offer both gateway and intelligent branch solutions.

Gateways provide essential communications for your branch and data center, interconnecting the IP world to the traditional PSTN world. They are supported by several other key functions including firewalls, call admission control, SIP proxy, analog adapters and other functions. Our gateways also provide signaling interworking and survivability functions (in case of WAN failure).

We provides a wide range of gateways for small, medium, large and very large Branch and data-center applications. These include Survivable Media Gateways for up to 2,000 users and non-survivable media gateways for smaller branches of eight to 100 users. Other combinations are also available to provide survivability for smaller branch sizes by using OpenScape Branch.

In addition to these options existing HiPath 3000 and HiPath 4000 systems can be used as gateways in OpenScape Voice networks. This has the advantage of investment protection and enabling a smooth migration from older systems to OpenScape Voice based communications.
