Tata and Microsoft Elevate Teams Voice Calling in India

A Strategic Alliance for Modern Communication

Tata Communications and Tata Tele Business Services (TTBS) have announced significant collaborations with Microsoft to integrate traditional voice calling into the Microsoft Teams platform for Indian enterprises. This move addresses the growing demand for unified communication solutions in a hybrid work environment. By leveraging their respective platforms, GlobalRapide and Smartflo UCaaS, the Tata group entities are set to simplify how businesses manage voice and collaboration, ensuring regulatory compliance and enhanced productivity.

The Need for Integrated Voice Solutions

The shift to remote and hybrid work models has accelerated the adoption of collaboration tools like Microsoft Teams. However, a major challenge for businesses has been integrating their existing Public Switched Telephone Network (PSTN) calling capabilities into these digital platforms. This often involves complex hardware, separate management systems, and navigating India's stringent telecom regulations. Enterprises require a seamless solution that combines the collaborative features of Teams with the reliability of traditional phone calls, all within a single, secure interface.

Tata Communications' GlobalRapide for Enterprises

Tata Communications is targeting large Indian enterprises and multinational corporations with its GlobalRapide platform. This solution utilizes Microsoft's Operator Connect and Direct Routing to enable carrier-grade PSTN voice calls directly from any Teams device. This allows users to make and receive calls globally while maintaining compliance with local regulations. The platform offers an end-to-end managed service, covering deployment, integration, and management of Teams, endpoints, and session border controllers (SBCs) without requiring additional hardware investment.

Sriram Sampath, Vice President of Unified Communications and Collaboration at Tata Communications, noted, “Our collaboration with Microsoft on Operator Connect for Teams will further improve workforce productivity and efficiency for businesses, while helping them meet local regulations and standards.” The partnership leverages Tata Communications' extensive global network, which spans over 190 countries and includes partnerships with more than 700 mobile network operators.

TTBS's Smartflo UCaaS for Scalability

Simultaneously, Tata Tele Business Services (TTBS) has launched its Smartflo Unified Communication as a Service (UCaaS) solution, also integrated with Microsoft Teams. Developed in partnership with AudioCodes, Smartflo UCaaS is designed to serve a broad spectrum of businesses, from small and mid-sized companies to large enterprises. It simplifies the deployment of voice services using the AudioCodes Live Platform, which provides automation, orchestration, and real-time monitoring.

Vishal Rally, Sr. Vice President at Tata Teleservices, stated, “Smartflo UCaaS has been developed with an endeavor to seamlessly bridge the gap between remote employees and the office while enhancing business efficiency.” This offering replaces traditional PBX systems with a cloud-based call control system, allowing employees to make PSTN calls from any device using their corporate network.

Understanding the Technology: Operator Connect vs. Direct Routing

The solutions from both Tata entities rely on two key Microsoft technologies to connect Teams to the PSTN:

• Operator Connect: A managed service model where businesses can choose a participating telecom operator like Tata Communications directly from the Teams admin center. It simplifies setup and management, as the operator handles the backend infrastructure.
• Direct Routing: This option offers greater flexibility, allowing enterprises to use virtually any telecom provider by connecting their own SBCs to Microsoft Teams. It provides more customization but typically requires more technical expertise to manage.

This dual approach allows Tata to cater to different business needs, from those seeking a simple, fully managed solution to those requiring more control over their telephony infrastructure.

Market Impact and Future Outlook

This strategic alignment strengthens the position of both Tata and Microsoft in India's rapidly growing UCaaS market. For businesses, it provides a trusted, compliant, and efficient path to modernizing their communication infrastructure. By eliminating the need for separate systems for collaboration and voice, companies can reduce costs, simplify IT management, and empower their hybrid workforce with a unified tool.

Shruti Bhatia, Country Head at Microsoft India, commented on the partnership, “This collaboration reflects our commitment to delivering greater efficiencies and productivity gains for businesses across India.” As digital transformation continues, the integration of essential services like voice into core collaboration platforms will be critical for business agility and success.

Conclusion

The collaborations between Tata Communications, TTBS, and Microsoft mark a significant step forward for enterprise communication in India. By providing robust, scalable, and regulatory-compliant voice solutions within Microsoft Teams, they are enabling businesses of all sizes to enhance collaboration and productivity. This partnership not only addresses the immediate needs of a hybrid workforce but also lays the foundation for future innovations in unified communications.
