Business VoIP: Huawei Extends License for SPIRIT DSP TeamSpirit Voice and Video Engine Mobile

November 28, 2011
By Rajani Baburajan, Business VoIP Contributor

SPIRIT DSP, a provider of voice and video over IP has revealed that telecom equipment provider Huawei Technologies has extended its license with SPIRIT DSP for wideband Mobile business VoIP and video calling. Huawei has been an existing SPIRIT customer since 2007.


TeamSpirit Voice and Video Engine is a software development kit (SDK) for real-time IP calling/conferencing communications in business VoIP scenarios. It allows application developers and service providers to offer superior quality communications products to millions of global users.

A combination of scalable echo- and noise-free audio with scalable video, TeamSpirit delivers a high quality conferencing experience and enables many hours of battery life in wideband talk mode. The voice engine includes highly optimized standard voice codecs and a patent-free wideband error-resilient scalable SPIRIT IP-MR voice codec (IETF RFC 6262).

Within the video engine is SPIRIT's H.264 scalable video codec that is able to adapt streams to each peer's network and PC environments without heavy transcoding, and includes a multi-component stream protection module that compensates for network jitter and packet loss.

By selecting the SPIRIT DSP solution, Huawei can now deliver superior quality mobile communication solutions to service providers who are looking to capitalize on this rapidly growing market and differentiate their offerings with quality and time to market, according to SPIRIT's Chairman Andrew Sviridenko.

The solution will address the real challenge faced by operators, system integrators and equipment vendors to differentiate their IP communication offerings with a high quality voice and video calling experience, Sviridenko added.

Huawei's products and services are currently deployed in over 100 countries and serve 45 of the world's top 50 telecom operators, as well as one third of the world's population.

In a similar development, SPIRIT DSP recently announced that KT, a telecom operator in Korea, licensed the company's TeamSpirit Voice Engine Mobile. KT will be able to improve business capabilities and better leverage the growing popularity of VoIP calling in the Asia Pacific region through this license.
