Microsoft Lync Server 2010 Mobility Guide
This document guides you through the process of deploying the Microsoft Lync Server 2010 Mobility Service and the Microsoft Lync Server 2010 Autodiscover Service. When you deploy the Mobility Service, users can use supported iOS, Android, Windows Phone, or Nokia mobile devices to perform such activities as sending and receiving instant messages, viewing contacts, viewing presence. The Mobility Service also enables mobile devices to use some Enterprise Voice features, such as click to join a conference, Call via Work, single number reach, voice mail, and missed calls.
When you use the Microsoft Lync Server 2010 Autodiscover Service along with the Mobility Service, mobile devices can automatically locate the URLs for Lync Server Web Services and the new Mobility Service regardless of network location.
