The system consists of a true carrier grade Class 4 and Class 5 softswitch switching platform and high-density VoIP gateway designed to run over any IP based network. Additional features optimize operation over satellite products.

Architecture Fits a Variety of Applications

The scalable and flexible architecture enables you to implement unique interactive voice response (IVR) applications. Examples are prepaid calling cards and prepaid fixed line in addition to basic VoIP telephony services. With its incremental scalability, you can deploy VoIP systems that match requirements typically found in emerging markets.

The key advantages of the Softswitch system are downward scalability, carrier-grade high availability, a software based IVR and service creation environment, and optimization for satellite networks sets.

The ViaSat VoIP Softswitch system is also available to augment Verso/Clarent VoIP networks.
