Unified Comms Radio over Internet Protocol (RoIP) system

U.S. Army Redstone Test Center


Redstone Test Center Mission Operations Control Center (RTC-MOCC)
Redstone Arsenal


A Unified Communications system that integrates diverse communication assets, including tactical radios, public or private telephones, cell phones, and computer workstations. The system provides mission-critical, reliable voice services for the following:

  • MOCC operators
  • Test range personnel
  • Flight test logistics staff
  • Pilots
  • Emergency first responders

Powerful Suite of Voice & Communication Products

Replace the Redstone MOCC program’s legacy voice communication system, the Distributed Scalable Access Net (DSAN), which had reached the end of its product life cycle.

ASTi replaced the DSAN with its Voisus product line. Voisus, a modern, proven IP-based communication system, uses robust, redundant servers and low-cost PCs with touchscreens at the operator end points. As a result, the MOCC can easily maintain and expand the system as their program requirements change.

Accelerated Delivery, Deployment, & Integration

Accommodate the customer’s aggressive schedule, minimizing system downtime during the transition.

To meet the customer’s aggressive schedule, ASTi accelerated the system’s delivery and integration, maintaining its critical communication role and minimizing downtime. ASTi’s application engineers helped RTC staff complete installation, validation testing, and training in only five days. After fielding tasks were complete, the test center staff performed an immediate, system-wide activation, shutting off the legacy system and bringing the Voisus system online.

Network-Based Record & Replay

Provide a reliable, user-friendly recording system that can log and export all voice communication for incident investigation and after action review.

ASTi provided the Communications Logger, a network-based, redundant system that continuously logs traffic from all communication assets to a RAID-capable disk. This single system can record thousands of endpoints on the network at once, including the following:

  • RoIP
  • Network intercom
  • Calling and conferencing
  • Voice over Internet Protocol (VoIP)
  • Public telephone traffic

Customers can access the Replay tool from a browser at any workstation on the network. As a result, recordings are easy to retrieve and review.

High Reliability

Provide a system with increased reliability and capacity, ensuring the safety of MOCC aircraft and range personnel.

To increase Voisus’ capacity and reliability, the customers added redundant network servers to the system using Voisus’s cloud configuration. These servers include the following reliability features:

  • Automatic load balancer
  • Failover protection
  • Resiliency options
  • Hard-disk RAID


Provide a system that is interoperable across the DoD's distributed training programs for inclusion in DIS-based Live, Virtual, and Constructive (LVC) events.

The Voisus Unified Communications system is field-proven interoperable across all of the DoD’s training programs, including the following:

  • Air Force Distributed Mission Operations (DMO)
  • Army Live, Virtual, Constructive-Integrating Architecture (LVC-IA)
  • Naval Aviation Simulation Master Plan (NASMP)
  • Navy Continuous Training Environment (NCTE)
  • Marine Corps Aviation Distributed Virtual Training Environment (ADVTE)
  • Joint National Training Capability (JNTC)
