Microsoft Lync is an enterprise-ready unified communications platform. A business version of Skype, if you will, that connects people everywhere, on Windows 8 and other devices, as part of their everyday productivity experience.
The integration will give Skype and Lync users that ability to contact each other, launch IM text sessions and communicate via audio calls. The integration should be delivered to customers in June with video conferencing integration coming later.
Additionally, Microsoft is planning to release Windows Phone 8 and iOS applications next month for Lync 2013. The apps will allow users to do voice-over-IO and video-over-IP communications. With over five million voice Lync seats sold, the new Lync app and integration with Skype may give Windows Phone a push in the business end of the market.
