OpenScape Voice

Comprehensive voice and unified communications

OpenScape Voice is a carrier-grade, native SIP-based soft-switch, providing comprehensive voice features across the IP network. It is based on OpenScape UC Sever and is scalable from 300 to 100,000 users on a single system - and virtually unlimited users in a network.

Because OpenScape Voice can support up to 3,000 branches and 6,000 business groups with multi-tenant capabilities, it is ideal for large-scale enterprise networks and service providers. It also has carrier-grade reliability and resiliency, and uses open standards throughout the design. OpenScape Voice includes standard IT virtualization and management options.

If you use SIP trunking or need to support many remote users, consider our OpenScape Session Border Controller (SBC), which is designed to work closely with OpenScape Voice. It acts as a ‘voice firewall’ to solve any SIP security and interoperability issues.
