FRISCO, TX / ACCESS Newswire / October 27, 2026 / Tango Networks, a leader in enterprise mobile convergence, and Vola Networks, a provider of communications hardware and POTS replacement solutions, today announced a strategic partnership to bring native cellular voice, compliant enterprise messaging, and modern POTS (Plain Old Telephone Service) replacement to service providers and enterprise partners across North America.

As telecommunications carriers accelerate the phase-out of legacy copper networks, businesses face urgent pressure to migrate critical analog equipment, such as elevator emergency phones, fire and security panels, and emergency call boxes, without costly hardware replacements. At the same time, organizations need managed, compliant alternatives to personal mobile texting and unmanaged third-party messaging apps. The joint solution bridges legacy analog infrastructure and modern cellular networks, providing a future-proof pathway away from copper lines while extending corporate communications to mobile workforces.

Modernizing POTS Infrastructure with Cellular VoLTE

The collaboration pairs Vola Networks' purpose-built hardware gateways with Tango Networks' cellular connectivity and VoLTE capabilities, establishing a highly reliable cellular voice path for existing analog devices.

VoLTE is particularly critical for POTS replacement because emergency and life-safety applications depend on high-quality voice connectivity rather than basic data transmission. On supported cellular networks, VoLTE voice traffic receives dedicated Quality-of-Service (QoS) treatment and priority routing, ensuring reliable operational performance when it matters most.

Migration Path: Legacy Analog Device → Vola POTS Gateway → Tango VoLTE → Cellular Network

By combining specialized POTS replacement hardware with cellular voice connectivity, service providers and MSPs can:

• Migrate Critical Equipment: Connect existing analog alarms, call boxes, and emergency lines over cellular networks without replacing the underlying hardware.
• Eliminate Copper Dependency: Provide a seamless transition off retiring PSTN copper infrastructure.
• Scale Across Locations: Deploy standardized, multi-site POTS replacement solutions efficiently across enterprise portfolios.

The combined capabilities of Tango Networks and Vola Networks are already delivering real-world results. In a recent deployment with OneCloud, the companies helped a North Carolina municipality modernize critical communications infrastructure across 50 municipal and police locations. The project successfully transitioned all 50 locations in just three weeks while retaining 100% of existing telephone numbers, demonstrating the scalability and practical value of their combined POTS replacement solution.

Extending Enterprise Mobility, Messaging, and Governance

In addition to physical line modernization, the underlying mobile engine allows partners to capture mobile communications revenue and extend corporate UC platforms directly to smartphone endpoints:

• Enterprise Business Messaging: Connects employees via compliant, app-free SMS/MMS integrated directly into smartphone native dialers and corporate platforms using corporate business numbers.
• Network-Layer Compliance & Governance: Captures and archives mobile voice and text at the network layer, helping enterprises satisfy strict regulatory standards (including HIPAA and MiFID II).
• Mobile Analytics & Intelligence: Provides centralized reporting and visibility across mobile communications, establishing an AI-ready foundation for conversational intelligence.

"The retirement of copper lines creates an urgent need for practical POTS replacement, while modern enterprises demand mobile-first workforce connectivity," said Lee Essex, SVP of Sales and Marketing at Tango Networks. "By combining Tango Networks' cellular VoLTE engine with Vola Networks' purpose-built gateways, service providers can enable immediate line migration and unlock high-margin revenue through extended mobile communications."

"Vola has focused on solving the practical challenges of POTS replacement by connecting existing analog equipment to modern communications networks," said Joe Zhang, CEO of Vola Networks. "Our partnership with Tango Networks brings together Vola's purpose-built POTS hardware and Tango's cellular and VoLTE capabilities, providing service providers with a reliable path from legacy copper to modern cellular connectivity."
