Secure VoIP for Government & Defense

In the defense, intelligence, and government sectors, voice is more than a communication channel, it’s a strategic asset.

USTelco’s Secure VoIP solutions deliver compliance-aligned, encrypted, and hardened voice infrastructure built for federal agencies, national security programs, and contractors operating in high-risk, high-assurance environments.

“We don’t just route voice. We secure command, continuity, and control.”
