TeamSpirit Mobile 4.0 Engine Brings Voice&Video Over IP to RCS, Provides Telcos with an Effective Weapon against OTT Competitors

SPIRIT DSP, the world's #1 voice and video over IP engines provider, serving more than 1 billion users in 100+ countries, today announced a new version of its VVoIP software SDK (Software Development Kit), TeamSpirit® Voice&Video Engine Mobile 4.0, that provides interactive mobile HD voice and video calls in RCS (Rich Communication Suite). TeamSpirit Voice&Video Engine Mobile 4.0 is compliant with the RCS 5.1 specification, the last version of the GSMA-driven standard for carriers' IP services, which allows telcos together with developers to quickly bring high-quality IMS voice and video calling functionality to their RCS-compliant services, applications and devices. The new engine is also fully compatible with standard SIP, IMS and VoLTE specifications.

TeamSpirit Voice&Video Engine, encompassing the new RCS communication standard, provides telcos with an easy-to-use SDK to create rich HD voice and video applications and bring them to market in record time, allowing them to remain more competitive and keep subscribers satisfied by responding more rapidly to their expectations for high quality voice and video calling on LTE networks. SPIRIT customers, such as BroadSoft, Huawei, KT, LG U+, Maaii and Reliance have developed or are now developing RCS applications and services using TeamSpirit Voice&Video Engines.

An approved by the International Telecommunication Union (ITU) standard, the RCS 5.1 specification aims to provide fully interoperable and standards-based rich functionality to end users, such as IM, presence, sharing, as well as voice and video over IP calls. The specification allows telecom operators to effectively compete with innovative and agile OTT (Over-The-Top) service providers, retain and even expand their subscriber base with high-quality, feature-rich, standards-based mobile applications available across a wide set of handsets and mobile networks.

"It is not only cross-platform messaging services that are killing telcos SMS traffic. Without HD voice and video over IP as a part of carriers’ RCS offering, irreparable loss of voice revenues is the challenge telcos have to deal with right now”, said SPIRIT's Chairman Andrew Sviridenko. “TeamSpirit Voice&Video Engine Mobile has been recognized by carriers around the world as an effective way to remain more competitive with OTT, bring richer RCS calls to their subscribers, enhance the value of LTE networks and keep their subscribers connected."

SPIRIT will be demonstrating TeamSpirit Voice&Video Engine Mobile 4.0 integrated into SPIRIT partners’ RCS applications at Mobile World Congress 2013 in Barcelona, Feb. 25–28 at booth #6F87 in Hall 6.

The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new data-driven world, marketplaces reign supreme while interoperability, APIs and applications deliver un...
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
There are so many tools and techniques for data analytics that even for a data scientist the choices, possible systems, and even the types of data can be daunting. In his session at @ThingsExpo, Chris Harrold, Global CTO for Big Data Solutions for EMC Corporation, will show how to perform a simple, but meaningful analysis of social sentiment data using freely available tools that take only minutes to download and install. Participants will get the download information, scripts, and complete end-to-end walkthrough of the analysis from start to finish. Participants will also be given the pract...
The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, along with new ways to engage with users.
Internet of Things (IoT) will be a hybrid ecosystem of diverse devices and sensors collaborating with operational and enterprise systems to create the next big application.

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
Can call centers hang up the phones for good? Intuitive Solutions did. WebRTC enabled this contact center provider to eliminate antiquated telephony and desktop phone infrastructure with a pure web-based solution, allowing them to expand beyond brick-and-mortar confines to a home-based agent model. It also ensured scalability and better service for customers, including MUY! Companies, one of the country's largest franchise restaurant companies with 232 Pizza Hut locations. This is one example of WebRTC adoption today, but the potential is limitless when powered by IoT.
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

WebRTC is about the data channel as much as about video and audio conferencing. However, basically all commercial WebRTC applications have been built with a focus on audio and video. The handling of “data” has been limited to text chat and file download – all other data sharing seems to end with screensharing. What is holding back a more intensive use of peer-to-peer data? In her session at @ThingsExpo, Dr Silvia Pfeiffer, WebRTC Applications Team Lead at National ICT Australia, will look at different existing uses of peer-to-peer data sharing and how it can become useful in a live session to...

"Matrix is an ambitious open standard and implementation that's set up to break down the fragmentation problems that exist in IP messaging and VoIP communication," explained John Woolf, Technical Evangelist at Matrix, in this interview at @ThingsExpo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.
WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.
