Spirit DSP announced that KT has licensed the company's TeamSpirit Voice Engine Mobile, an SDK (Software Development Kit) that enables high-definition (HD) VoIP (voice over IP) calling on a broad range mobile devices.
The VoIP rates are 80% cheaper for intercity calls, 20% lower for calls to mobile phones and 95% cheaper for international calls.
According to the Korean Communications Commission (KCC), the number of paid Internet telephony subscribers broke the 10 million mark this year.
“With the growing popularity of VoIP calling in Asia Pacific, coupled by the sheer volume of mobile data usage, the problem of lost or jammed traffic becomes a real barrier for smooth, quality communications over mobile networks,” said Alexander Kravchenko, SPIRIT’s VP for sales.
The TeamSpirit Engine is a SDK for real-time IP calling/conferencing communications, allowing business application developers and service providers to offer superior quality communications products to millions of global users.
The TeamSpirit Engine software uniquely combines scalable echo- and noise-free audio with scalable video, a necessary marriage to ensure the highest quality conferencing experience. TeamSpirit 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-MRTMvoice codec (IETF RFC 6262). The video engine includes 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 it includes a multi-component stream protection module that compensates for network jitter and packet loss.
