October 24, 2011 –- SPIRIT DSP announced today that LG U+ (formerly known as LG Telecom), South Korean's leading mobile and telecommunications service provider, has licensed SPIRIT's TeamSpirit Voice & Video Engine Mobile to power HD-quality VoIP and video-calling on mobile devices.

South Korea has one of the world's most vibrant IP Communications markets backed by strong support from the government. A dedicated area zone for VoIP telephone numbers was introduced several years ago, followed by a number portability option that made it possible for people to move to VoIP-calling without changing their phone number. A wide mobile VoIP adoption thanks to a great wireless broadband infrastructure, new smartphones from Korean handset OEM giants and high smartphone adoption rates were recently reported by the Korea Communications Commission (KCC). In just 18 months, the number of smartphone subscribers in South Korea has exploded more than ten-fold to top 10 million (or around a fifth of the population) stimulating local carriers to deploy their own mobile VVoIP (voice and video over IP) services to retain their customers from migrating to Skype and Google mobile voice and video services.
