Start with the right platform. The leading software-based voice communications system.
OpenScape Voice is a native SIP based real-time Voice over IP system scalable up to 100,000 users per system and a virtually unlimited number of users when OpenScape Voice systems are networked. It provides a complete and feature-rich set of business class features and perfectly fits into data center installations running as a virtualized appliance on VMware hypervisors. Alternatively, it runs on highly reliable, redundant and fault-tolerant hardware.
OpenScape Voice can be deployed on premise or in data centers as Private Cloud or as multi tenant capable Hosted/Public Cloud solution.
OpenScape Voice is a carrier-grade enterprise voice solution meaning 99.999% reliability –that translates to less than 5 1/2 minutes of downtime per year! The server nodes are designed so that if one fails, the other server node can support 100% of the call load. The server nodes can operate with 100% call failover support even when they are geographically separated, greatly reducing the costs, and the amount of time implementing a disaster recovery strategy. And remote offices can be protected with an OpenScape Branch solution – a survivable branch office solution for OpenScape Voice. OpenScape Branch not only offers survivability, but it includes a media server, firewall, Session Border Controller, and integrated PSTN gateway, all in a single appliance form factor. The value of OpenScape Branch goes beyond survivability, its activity contributes to lower the overall deployment, bandwidth and service costs.
