Voisus Developer Suite

ASTi offers a number of different ways to interact with and manage our Voisus communications products.

From desktop clients for PCs to realistic radio skins on mobile tablets to browser-based comms clients, ASTi probably already makes a user interface that will meet your requirements. But in the unlikely event that our suite of interfaces doesn't quite fit the bill, we also provide, at no cost, a way for our customers to develop their own applications, and integrate them directly with the Voisus comms environment.

Roll Your Own Client

If you want to design your own client user interface, the Voisus Remote Client Control (VRCC) library puts the power of Voisus Clients in your hands. This cross-platform C++ library allows developers to create powerful custom applications that enjoy the same capabilities as ASTi's own Voisus Client programs. ASTi's Voisus Software Development Kit (SDK) provides documentation as well as sample C++ and C# code that demonstrates how to get started using the library to connect to the Voisus server, configure the client, interact with radios, stream audio, and more. In fact, our developers use this same VRCC library and Voisus SDK to create our standard user interfaces.

Voisus Server Control

For many customers, having a custom Voisus Client GUI is sufficient for their training needs. But if you wish to "white-label" or provide closer integration to instructor stations, ASTi gives you a way to programatically configure the Voisus Server. The Voisus Server HTTP API relies on modern web technologies to provide a self-documenting, RESTful interface which allows customer-developed programs access to, and control of, Voisus's powerful features.

Via the Voisus API, customers may:

  • Create, configure, update and delete Scenarios, Roles, Radios, and Commplans
  • Manage client connection settings
  • Run and stop Scenarios
  • Download Voisus client applications
  • Monitor exercise radio traffic
  • Modify network configuration

For example, some customers use the HTTP API (HAPI) to integrate the configuration and management of Voisus directly into their Instructor Operator Station. This allows the networked communication system to be seamlessly integrated into the rest of the simulation center.
