SPIRIT Offers RCS-ready Mobile VVoIP Engine SDK to Carriers and Smartphone OEMs

May 30, 2012 – SPIRIT DSP, the world’s top voice and video over IP engines provider, announced today that its TeamSpirit® Voice&Video Engine Mobile supports the recently released version of the Rich Communication Suite (RCS 5.0) specification, which now includes the IMS-based definitions for mVVoIP (Mobile Voice and Video over IP) calling and conferencing. RCS is a GSMA-driven standard for carriers’ IP services that aims to provide fully interoperable and standards-based rich functionality to end users, such as IM, presence, sharing and voice and video calls.

The past year has been marked by a multi-billion dollar decrease in operators’ revenues, mostly resulting from subscribers using third-party apps. The RCS specification will allow telecom operators to compete with alternative OTT (Over-the-Top) mobile 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.

RCS is a framework for creating mobile IMS clients. RCS 5.0 applications integrate with telecom operators’ IMS infrastructures, implementing voice and video call functionality using IMS-compatible media streaming and SIP signaling. This is where SPIRIT solutions come into play. TeamSpirit Voice&Video Engine Mobile is a digital signal and network processing SDK (Software Development Kit) designed and ideally positioned for the rapid and cost-affordable development of high-quality mVVoIP applications. TeamSpirit features modules for traditional IP network impairments compensation, such as echo, latency, jitter, congestion and packet loss, with various voice and video packet loss robustness and quality improvement algorithms to maintain call quality in changing network channel conditions. The Engine is fully compatible with standard SIP, IMS and VoLTE specifications and has been tested in thousands of industry standard tests, as well as benchmark and interoperability tests (BMT/IOT) conducted by the largest carriers and OTT service providers. With TeamSpirit Voice&Video Engine Mobile, developers can quickly bring high-quality IMS-compatible voice and video calling functionality to their RCS services, applications and devices. SPIRIT customers Huawei, KT and LG U+ are good examples of Tier1 operators that have recognized the power of RCS and are actively creating applications and services based on this powerful standard.

“The TeamSpirit Voice&Video Engine Mobile SDK provides simple, yet comprehensive mVVoIP-optimized calling APIs, along with compatibility with RCS, IMS and VoLTE specifications, allowing operators and smartphone developers to avoid unnecessary engineering efforts and rapidly and cost-affordably bring to market embedded RCS  applications with outstanding HD calling quality on a variety of mobile platforms, including Android and iOS,” said SPIRIT’s Product Marketing Director Alexander Samarin. “Additionally, with TeamSpirit’s powerful OTT-focused optimization, a service provider can run RCS -based mVVoIP calling services not only over VoIP-optimized access networks, but over any generic (WiFi/3G/4G) data connection, bringing FaceTime quality, Skype ubiquity and carrier-grade reliability to the RCS ecosystem.”

The TeamSpirit Voice&Video Engine provides seamless compatibility between RCS and VoLTE services. TeamSpirit Engine includes resource-efficient voice and video codecs, echo and noise processing, advanced tools for stream protection and adaptation to changes in network, execution and physical environments. Apart from standard IMS codecs, SPIRIT offers industry leading IP-MR™ (IETF 6262) adaptive and error-resilient voice coding technology that has been selected by Tier1 telecom operators to provide HD voice communications for the millions of users of their commercially available VAS services. TeamSpirit Voice&Video Conferencing Engine is an additional server-side module bringing all the tools and power of TeamSpirit’s robust high-quality calling to centralized communication scenarios. TeamSpirit Conferencing is based on scalable voice and scalable video technology which enables high-density (1000 video channels per $4K server) multipoint conferencing with accurate adaptation to specific capabilities of every user’s network connection, screen size and terminal power.
