HONG KONG – July 31, 2025 – Flyingvoice, a global leader in VoIP and IoT communication solutions, today announced that its PR12 4G VoIP ATA (Analog Telephone Adapter) has successfully achieved comprehensive network  certifications from Verizon, AT&T, T-Mobile, FirstNet, ETL, and NDAA compliance.

This multi-carrier certification milestone establishes the PR12 as a universally compatible, mission-ready analog telephony solution—clearing the path for enterprise, healthcare, and retail organizations to replace legacy PSTN lines with a carrier-grade, zero-downtime communication system.

Why Carrier Certifications Matter

In the transition from PSTN to IP-based networks, device-level carrier validation is non-negotiable. Achieving certification across all major U.S. carriers—including the rigorous public safety requirements of FirstNet—guarantees that the PR12 operates safely and reliably on North American spectrum. These certifications verify radio frequency (RF) compliance, network signaling integrity, and emergency call handling, ensuring the device never compromises carrier infrastructure while maintaining always-available connectivity for critical endpoints such as emergency phones, fax machines, and alarm panels.

Engineered for Critical Uptime

The PR12 is built to keep analog systems—including fax machines, alarm panels, and Emergency Phone—operational even during power outages or network failures. Core product features include:

• Seamless PSTN Replacement – Dual FXS ports with native support for T.38 fax, Contact ID alarm protocols, and V.150.1.
• 24-Hour Battery Backup – Internal power reserve ensures voice and alarm connectivity for a full day during an outage.
• SmartPath Network Auto-Switch – Automatically fails over between WAN and LTE without call interruption.
• Dual-SIM Redundancy – Supports failover and fallback between two carriers, eliminating single points of signal weakness.
• PoE-Ready Deployment – Dual Gigabit Ethernet ports with PoE input for flexible installation.

“Legacy systems cannot tolerate downtime, yet many organizations are forced to migrate off PSTN,” emphasized Steve Fang, CEO of Flyingvoice Networks. “With FirstNet certification for public safety and NDAA compliance for government projects, the PR12 is now the most trusted ATA for critical infrastructure.”

The PR12 is available immediately for volume orders through Flyingvoice’s North American distribution partners.
