Richard talks to Justin Morris about the mobility component of Lync. Only just released, Microsoft has Lync clients for iPhone, Android, Symbian and Windows Phone 7. Justin talks about how the mobile Lync client extends Lync's concept of presence to the smartphone, so that people working in the enterprise can connect and communicate with their fellow employees on the road the same way. The conversation digs into the challenges of data connectivity versus cell telephony, and how Lync provides a call-via-work mechanism to centralize and control cellular call costs. And don't worry - Skype comes up in the conversation too!
