New York (NYSE) & Mumbai (NSE & BSE) – April 22nd 2013 – Tata Communications, a leading provider of A New World of Communications, today launches its international HD voice termination service. The new service enables MNOs to route international HD calls via end-to-end IP, without transcoding, ensuring that HD customers calling HD-compatible destinations internationally will receive the full HD experience.

The launch will become the platform that enables a broad community of HD destinations as a result of Tata Communications’ network which is connected to 210 mobile network operators via IP voice interconnect. Twenty-six of these operators are HD-ready with 4 operators already in deployment for HD Voice on Tata Communications’ network.

HD voice service ensures that calls are clearer and background noise is significantly reduced, leading to longer calls and increased revenues for MNOs. HD voice will play a critical role in enabling MNOs to increase customer satisfaction and reduce churn on premium international calling and high-margin roaming. The improved quality of HD voice simulates a sense of being in the same room during a telephone conversation; hence, users are likely to spend longer on calls. A better calling experience also gives mobile operators a competitive advantage over OTT providers in terms of quality of service.

Michel Guyot, President, Global Voice Solutions, Tata Communications says, “Our focus on improving voice quality through innovations such as HD voice has led to 28% year-on-year volume growth from key retail service providers (MNOs and OTTs). We will leverage our community of IP-connected MNOs to quickly enable HD voice calls between the widest possible range of destinations, maximising the benefits of premium call quality for our partners and their end users.”

In line with increasing demand for next generation communication services including the rise of HD voice-enabled smartphones, Tata Communications has created a community of MNOs globally, delivering better inter-provider mobile service delivery and management through its IPX+ connectivity platform. The company’s HD voice service is part of a strategy to enable mobile operators to capitalise on the latest technology innovations in the mobile broadband space via better inter-provider mobile service delivery and management.

Tata Communications’ voice capabilities are anchored by its network of submarine and terrestrial cables as well as a Tier-1 IP backbone with connectivity to over 400 PoPs which reach more than 200 countries and territories. The company is currently the world’s largest international wholesale voice carrier, carrying more than 1 billion voice minutes per week with 30+ voice strategic sourcing partnerships signed to date.

Tata Communications will be at International Telecoms Week (ITW) in Chicago, May 13th-15th 2013.
