Ensure India-ready regional regulatory compliance right from the start
India’s telecom landscape has around twenty-three highly regulated regions, making compliant voice deployments complex. As OSP guidelines evolve, enterprises need to navigate legacy systems and regulations, which can be time-consuming and expensive. Tata Communications brings deep expertise, the right licenses, and proven SIP Trunk cloud deployment experience in all regions, enabling seamless transitions, reduced integration hassles, and simplified operations for your business.
Address common deployment roadblocks

Dedicated service area licenses
Enterprises need licensed partners to transition domestic PSTN to the cloud. Avoid switching issues and unlock region-wide transformation with a partner authorised across all telecom circles.

Navigating legacy infrastructure
Outdated technology limits growth and increases costs. Streamline the shift to cloud and minimise multi-vendor complexity by working with a comprehensive service expert.

Deployment complexity
Cloud-based communications rollouts can be complex and multifaceted. Leverage Tata Communications’ extensive implementation experience for a hassle-free transition and robust stakeholder satisfaction.
Unlock growth in India with a compliant voice partner
