SPIRIT DSP, a voice and video over IP engines provider, on Tuesday said that Korean Telecom giant 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. 

KT is S. Korea's top fixed-lined operator and the No. 2 mobile carrier in the region. 

Internet telephony is Korea's prominent daily communications medium.  The VoIP rates are 80 percent cheaper for intercity calls, 20 percent lower for calls to mobile phones and 95 percent 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 SPIRIT's VP Sales Alexander Kravchenko. "The priorities of consumers and businesses are shifting from an experience that's 'good enough' to a demand for a higher quality mobile HD VoIP experience that SPIRIT engine delivers to KT's millions of mobile subscribers."
