SPIRIT DSP, the world's top voice and video over IP engines provider, on Wednesday said that  that its TeamSpirit Voice&Video Engine Mobile supports the recently released version of the Rich Communication Suite enhanced (RCS-e 5.0) specification, which now includes the IMS based definitions for mVVoIP (Mobile Voice and Video over IP) calling and conferencing.

 RCS-e 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-e 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-e is a framework for creating mobile IMS clients. RCS-e applications integrate with telecom operators' IMS infrastructures, implementing voice and video call functionality using IMS compatible media streaming and SIP signaling.

"The TeamSpirit Voice&Video Engine Mobile SDK provides simple, yet comprehensive mVVoIP optimized calling APIs, along with compatibility with RCS-e, IMS and VoLTE specifications, allowing operators and smartphone developers to avoid unnecessary engineering efforts and rapidly and cost affordably bring to market embedded RCS-e applications with outstanding HD calling quality on a variety of mobile platforms, including Android and iOS," said SPIRIT's Product Marketing Director Alexander Samarin.
