Challenges &

The Air Force selected components from ASTi’s Voisus product line to replace three obsolete, disjointed, and separately managed systems. Two of these systems were end-of-life COTS products that needed a technical refresh, while the third was an old, GOTS recording system that lacked life-cycle support. The newly installed Voisus configuration replaced this outdated technology with a single, web-based command and control UI that was easy to use.

The challenge requirements are listed in blue; ASTi's applicable components are in black:

Expanded Footprint

Expand radio-over-IP footprint to support networked distribution of live tactical radio and virtual radio communications to a large number of computer-based staff and trainees and DoD virtual flight simulators.

ASTi configured the Voisus system to provide unified voice communications for 100 computer-based staff and trainees, with access to a bank of tactical radio feeds, simulator-based comms, and voice chat rooms.


Make replacement system interoperable across the DoD's distributed training programs.

Voisus is field-proven interoperable across all of the DoD’s training programs, including Air Force DMO, Army LVC-IA, Navy NASMP and NCTE, Marine Corps ADVTE, and Joint Staff JNTC.

Web-Based Command & Control

Provide centralized configuration and management services.

The customer can access Voisus’s configuration and management services from anywhere on the network using a browser.

Expedited Fielding

Expedite delivery, replace the legacy system without changing interfaces or connectors to the rest of the infrastructure, and follow up with an aggressive fielding schedule.

Voisus products shipped from stock and provided a low-overhead, drop-in, plug-replaceable solution.

Reduce Time & Manpower

Reduce the time and manpower needed to set up and conduct exercises, but minimize product training time.

To install, configure, and use the equipment: with the assistance of an ASTi engineer, the customer completed installation and testing within three days, and system administration training within one.

Reduced Size, Weight, & Power

Reduce size, weight, and power requirements versus the old system.

The new ASTi system occupies five times less rack space than the legacy equipment it replaces.

Expansion Path

Provide a clear, risk-managed path to additional capabilities.

Voisus is a modular product line, which means that expanding the footprint and introducing enhanced capabilities like telephone integration, virtualized servers, or operation with cloud-based architectures is as simple as adding more Voisus product building blocks.

Product Lifecycle Sustainment

Vendor must have a proven product lifecycle sustainment track record.

ASTi conducts sustainment-related activities as part of our continual product lifecycle management process. Over the lifetime of a product, ASTi identifies and mitigates issues related to OS migration and hardware component availability and obsolescence. ASTi customers inherit these commercial-off-the-shelf (COTS) product benefits, minimizing the downstream impact of sustainment issues.
