Voisus Data Sheet

ASTi's Voisus platform delivers high-fidelity communications and audio over IP networks to a variety of user interfaces. The platform consists of a Voisus server running Voisus server software. Voisus client software GUIs can be downloaded to computers and tablets through the Voisus web interface.

Software Overview & Features

Voisus software consists of server and client software components that provide high-level features, such as the following:

  • Secure, web-based management (https)
  • Ethernet network-based architecture
  • Secure Shell (SSH)
  • Customer-programable interface:
    • HAPI: A HTTP Application Program Interface allows developers to create their own Voisus server web interfaces for creating exercise scenarios and managing client operators.
    • SAPI: A Streaming Application Program Interface allows developers to create their own apps that stream data from the Voisus server, such as a radio monitor displaying operator receive/transmit states.
    • VRCC Library: The Voisus Remote Control Client (VRCC) library provides an interface for developers to build custom communications client GUIs for computers and tablets.
  • DIS interoperability

Go to the Voisus Quick Start Guide for additional features.
