Secure Communication for High-Risk Environments

Designed to support everyday voice communications, the Avaya J179-TSG offers eight programmable lines and is ideal for professionals, executives, call centers, and sales teams in secure settings. However, what makes this model stand apart is its TSG-6 certification by the U.S. Committee on National Security Systems (CNSS), ensuring compliance with stringent telecommunication security standards. This model has also been approved by the U.S. National Telecommunications Security Working Group, making it a trusted solution for environments where confidentiality is mission-critical.

Advanced On-Hook Security & Positive Disconnect Technology

Security risks posed by traditional IP phones — such as wiretapping, tampering, or covert signal injections — are eliminated thanks to the positive-disconnect circuitry built into the J179-TSG. This technology guarantees no audio leaves the microphone circuitry while the handset is on-hook, preventing any form of unintended audio surveillance.

Additionally, both “Hold” and “Mute” security features are active, allowing users to pause conversations without fear of leakage. For increased physical security, the microphone can be permanently removed, and the speakerphone functionality can be disabled where required.

Certified, Hardened, and Ready for Deployment

This security-enhanced IP phone is available in two classes:

Class A: Comes with a certified power supply unit (PSU) and offers manual and automatic security controls.

Class B: Operates via Power over Ethernet (PoE) and is optimized for simpler deployments in protected networks.

Whether deployed in military installations, intelligence agencies, or federal offices, this device provides the confidence needed to hold secure voice conversations without compromise.
