BENGALURU,India and PLANO,Texas,Feb. 17,2022 --Ribbon Communications Inc.(Nasdaq: RBBN),a global provider of real time communications software and IP optical networking solutions to service providers,enterprises,and critical infrastructure sectors,today announced that it is collaborating with Infosys,a global leader in next-generation digital services and consulting,to deliver an integrated IT Managed Services offering to global enterprises.

The integrated solution enables global enterprises to seamlessly migrate from legacy on-premise PBX communications systems to Microsoft Teams Phone System Direct Routingin all geographic regions. Microsoft Phone System Direct Routing is the service inside of Teams that allows organizations to connect external phone lines and use Teams as an office phone system.

Ribbon's Microsoft-certified Core and Edge Session Border Controllers (SBCs)and Centralized Policy & Routing solutions provide key functionality in the Infosys Managed Services offering. The integrated solution has already been deployed by one of the world's largest brands as part of their global communications upgrade.

"It was important to design a solution that delivers multinational organizations a phone system migration strategy that provides them with the flexibility to gradually transition thousands of employees across a multitude of sites and geographic regions from legacy phone systems and contact centers to Microsoft Teams," said Steve McCaffery,Ribbon's Executive Vice President of Sales,EMEA and APAC. "The Infosys Managed Services offering leverages Ribbon's Microsoft-certified technology to connect and integrate legacy and new solutions,providing the organization's users with a seamless,superior communications experience both during and after the transition."

Kanagalu Manoj,Senior Vice President for Ribbon in India,added,"We have worked closely with Infosys for several years to develop and deliver a joint solution that would assist the largest enterprises in transforming their IT and voice communications infrastructure. In fact,our solutions have long been deployed in Infosys integration labs. We are extremely excited with the opportunity to continue to build on our successes and deliver comprehensive solutions that will help global enterprises successfully navigate their digital transformation journey."

Many large enterprises are geographically dispersed and have operations in Regulated and Non-Regulated countries. The integrated Infosys-Ribbon solution provides organizations with the flexibility to configure PSTN breakouts from a centralized software-based Ribbon SBC or from a Ribbon SBC deployed at branch office locations using Microsoft's Local Media Optimization (LMO) configuration. The integrated solution supports both architectures simultaneously. In addition,the solution delivers advanced call routing capabilities and eliminates the complexity that can typically be associated with large voice transformation projects. The solution also provides geo-redundancy and disaster recovery capabilities,regardless of global region.
