Ribbon Communications (RBBN) announced that TNS will incorporate Ribbon technologies into the TNS Hosted Cloud Connect solution to support modernization of legacy voice networks for Communications Service Providers (CSPs).

The fully managed, cloud-based, carrier-grade voice offering targets independent and rural operators that want to replace legacy switching infrastructure without owning and operating their own voice platforms. It is designed to maintain service continuity and voice quality while reducing operational complexity, cost and risk compared with traditional network replacement.

The solution leverages Ribbon's Application Server (AS), Session Border Controller (SBC) and Policy and Routing Server (PSX) alongside TNS Hosted Cloud Connect to provide a practical path from on‑premises infrastructure to cloud-based voice services.

session border controller technical
"Application Server (AS), Session Border Controller (SBC), and Policy"
A session border controller is a network device that manages and protects internet-based voice and video calls, acting like a combined receptionist and security guard that controls who can enter, how calls are routed, and whether they follow rules. For investors, it matters because these devices affect service reliability, security, regulatory compliance and operating costs for telecom and cloud communications providers, which in turn influence revenue risk and growth potential.
policy and routing server technical
"Session Border Controller (SBC), and Policy and Routing Server (PSX)"
A policy and routing server is a computer system used by brokers and trading platforms to check orders against rules and then send them to the right market or execution venue. It acts like a traffic director plus rulebook: it enforces compliance limits (best execution, order size, risk checks) and decides the fastest, cheapest, or required path for each order. Investors care because these servers affect where, how quickly, and under what restrictions their trades are executed, which can influence price and costs.

Fully managed cloud-based solution provides independent and rural operators with a seamless path to voice network modernization

PLANO, Texas, Sept. 9, 2026 /PRNewswire/ -- Ribbon Communications Inc. (Nasdaq: RBBN), a global leader in real-time communications technology, IP routing, and optical networking solutions, today announced that TNS, a global leader in trusted voice communications, will incorporate Ribbon technologies in the TNS Hosted Cloud Connect solution. The carrier-grade voice solution helps Communications Service Providers (CSPs) modernize their voice networks without the cost and complexity of owning and operating voice infrastructure.

Hosted Cloud Connect is purpose-built for CSPs seeking a practical modernization path that avoids the disruption, cost and risk of a traditional network replacement. The solution has already attracted interest from CSPs looking to simplify the management of complex voice environments by reducing the operational burden associated with maintaining legacy switching infrastructure while helping maintain service continuity, reduce operational complexity and support future communications services.

"CSPs need a practical path to modernize legacy voice environments without disrupting critical services," said Joe Dechant, Vice President, TNS. "TNS's and Ribbon's proven voice technologies can help CSPs reduce operational complexity, maintain service continuity and prepare for future communications needs."

Independent and rural operators face growing pressure from multiple directions. Voice services require extremely high levels of reliability, continuity and operational stability, making it difficult to simply "rip and replace" existing networks.  Residential and business customers expect more advanced communications services. These providers must also manage increasing regulatory requirements and a shrinking pool of specialized technical talent. To remain competitive, CSPs must invest in new services while controlling costs and preserving the reliability their customers expect.

Ribbon and TNS address these challenges by leveraging Ribbon's Application Server (AS), Session Border Controller (SBC), and Policy and Routing Server (PSX) and TNS Hosted Cloud Connect to help streamline the transition from on-premises infrastructure to cloud-based voice services while maintaining the voice quality, resiliency, and security required for carrier operations.

"For many CSPs, the challenge isn't deciding whether to modernize legacy voice switches, it's finding a cost-effective way to make the transition," said Elizabeth Page, Sr. Sales Director, Ribbon. "TNS Hosted Cloud Connect provides a practical path from legacy infrastructure to a modern cloud-based platform without sacrificing the resiliency, security, and service quality operators require. Together, Ribbon and TNS are helping CSPs simplify operations, lower costs, and extend the value of their voice business."
