Tata Communications upgrades network to support VoLTE

Indian carrier services firm Tata Communications has announced that its network is now ready to supply VoLTE services to operators connected to its IPX.

The firm said that customers of its operator partners will benefit from “near-instant” voice call setup and better sound quality on calls, including HD Voice interoperability between fixed and mobile networks.

Tata claims that the network upgrade will offer its operator partners improved voice quality, which will lead to increased usage and ultimately increased revenues. It added that investing in VoLTE would significantly reduce customer churn for operators, noting that VoLTE services and OTT VoIP services combined are forecast to be worth $16bn by 2017, according to Infonetics Research.

“Our VoLTE offering enables mobile operators to generate additional revenue through increased usage, especially in high-margin roaming scenarios and international calling,” said Christian Michaud, SVP product and business strategy for global voice services at Tata Communications.

“Adding VoLTE to the portfolio also provides mobile operators with a potential competitive advantage over OTT providers, who may not be able to match the quality of experience. This is especially true as video calling over LTE will be the natural evolution of VoLTE.”

In April last year, Tata Communications launched a service offering international HD voice call termination to mobile operators that have launched HD voice in their domestic markets. Prior to that, in January, the firm upgraded its trans-Atlantic TGN-Atlantic (TGN-A) subsea cable to run 100Gbps between New York and London.

The 2nd annual LTE Voice Summit is taking place on October 7th-8th 2014 at the Royal Garden Hotel, London. Click here NOW to download a brochure.
