SPIRIT DSP licenses enterprise video messenger with superior interoperability in source code

SPIRIT DSP was the nerve of ushering voice and video over LTE functionality first time in India couple of years ago. Reliance Jio, India largest 4G provider, inked contract with SPIRIT DSP to revive video and voice calling in India. SPIRIT is the engine behind many communication software platforms, including Skype, Apple, Microsoft, Viber and many others. The genesis of SPIRIT was carved by Moscow University graduate, Andrey Sviridenko in 1992. Initiating with an AI software product licensed to a small German company, the organization further ventured out its communication product line and rechristened itself to SPIRIT DSP (digital signal processing). The organization’s deftness is a blend of innovation prowess, high performance and reasonable license fees. SPIRIT DSP’s innovative carrier-grade voice and video software platforms are used by more than 1 billion people across 100 countries. In India, SPIRIT DSP has licensed its mobile voice and video engines to companies like Aricent and Reliance Jio, among others. Reliance Jio launched its LTE network in India on SPIRIT voice and video engines software, to enable the use of low-cost smartphone hardware that did not support Voice over LTE standard.

Perpetual innovation at every step of product development and promotion has escorted SPIRIT DSP from a ‘Garage startup’ to a global frontrunner in mobile Voice and Video over IP (VVoIP) engines, achieving global success by relying on the technical excellence of its computer scientists and by adjusting to market demands and challenges in a timely manner. During its 25 year journey, SPIRIT DSP has channelized its expertise across different software product categories, ranging from telecommunication and navigation to AI. While exporting its dexterity to US, Europe, and Asia, SPIRIT introduced VideoMost®, software video conferencing server product with web-browser and mobile clients in 2011. VideoMost®, product has several service provider partners in India now that deliver cloud services and on-premises video conferencing to Indian companies under their own brands based on the platform.

SPIRIT DSP also licensed its voice and video engines to Huawei, Ericsson, Polycom, Radvision (now Avaya) and DialogicAs competition intensified and Microsoft and Google began to develop VVoIP engines in-house (acquired multiple companies), SPIRIT DSP refocused its attention towards emerging technology giants in Asia.
