Voice over IP for Defense Communications

Defense VoIP: Beyond Commercial Systems

While commercial VoIP revolutionized business communications, defense applications demand capabilities far beyond Skype or Zoom. Military VoIP must support multiple classification levels simultaneously, integrate with tactical radios and SATCOM, survive electronic warfare attacks, and maintain NSA Type 1 encryption end-to-end. Our defense VoIP solutions meet these requirements while providing the user experience and cost savings of modern IP telephony. The result is a unified communications platform supporting everything from garrison desk phones to tactical command post operations.

Multi-Level Security Architecture

Our VoIP platform implements Multi-Level Security (MLS) to support simultaneous classified and unclassified communications on the same network infrastructure. Cryptographic separation ensures Top Secret conversations cannot leak to Secret or lower networks. Visual and audible classification indicators prevent accidental disclosure. The system meets NSA CNSSI 1253 security requirements and supports RED/BLACK network separation, enabling cost-effective deployment in secure facilities.

Tactical VoIP for Field Operations

Deployable VoIP servers enable command posts to establish secure voice networks within minutes of arriving at a forward location. The ruggedized servers support up to 1,000 users, with automatic failover for high availability. Integration with tactical radios enables radio-to-VoIP calls, allowing headquarters staff to speak directly with field units. SATCOM integration extends VoIP connectivity globally, enabling secure voice calls between deployed forces and home-base command regardless of distance.

Features for Command & Control

Our VoIP platform includes specialized features for military command operations. Conference calling supports up to 100 participants for multi-agency coordination. Priority and preemption ensure critical calls complete even when networks are congested. Call recording with tamper-proof audit logs meets legal requirements for operations and intelligence. Integration with common operating picture displays enables click-to-call functionality, allowing operators to initiate secure voice calls directly from tactical maps.
