In the above video you can see a demo at TechED 2011 in New Zealand for Microsoft's Lync, which is the inter-office communication and VoIP system. The app is slated for a Q4 release and will also be coming to iOS, Android and Symbian with Windows Phone said to receive the first and best. Other platforms will receive a fully featured app with integration, not just a mere port.
A question from the audience was greeted by a fairly exciting response with the final goal in WP7 being to integrate Lync into hubs in favour of a stand-alone application. Communication will be handled by the messaging hub and anything from the cloud will be handled in the Office hub. Voice and video will be dependant on the handset and OS.
You may also have noticed in the video we hear some talk surrounding front-facing cameras on Windows Phone handsets, which further confirms our recent article covering Skype and the secondary camera support. Are you excited for FF cameras, or wont you use them?
