Indian telecom operator Infotel, a subsidiary of Reliance Group, has licensed SPIRIT DSP Mobile Video Engine. Reliance intends to invest $10 billion in its LTE network and has selected SPIRIT's software products for voice and video calls over LTE.

By using SPIRIT engines, Reliance will be able to offer its subscribers high-quality services as an alternative to Skype over cellular networks and attract new high-value subscribers that used services from other operators and commercial OTT service providers.

SPIRIT DSP, a voice and video over IP engines provider, says that its engine plays a key role in providing HD voice and video quality as a part of IMS/RCS service infrastructure on Android and iOS smartphones and tablet PCs, as well as PCs with Mac OS or Windows.

"While the number of LTE networks is growing, the quantity of mobile devices models supporting VoLTE is extremely small. LTE phones and tablets mainly support only data transmission over an LTE modem, while voice and video are going via 2G/3G network. It’s an awkward situation for mobile operators who had hoped that phone OEMs would flood the market with 4G LTE-ready phones," said SPIRIT’s VP Alex Kravchenko.
