The VoIP capability means that formerly voiceless devices such as iPads that have data connections can now participate in Lync meetings. The new features also mean that devices that do support traditional cellular connections can instead tap into the meetings using VoIP over available Wi-Fi networks thereby conserving mobile data-plan minutes.
Also demoed at the conference was a voice call completed between a Skype client machine and a Lync client machine. So far only audio calls are possible.
Another demo brought voice and video to an iPad, a device that lacks native cellular voice support and videoconferencing capabilities. With a larger screen than mobile phones, the iPad can simultaneously display video of other meeting participants as well as a whiteboard, desktop sharing or data presentations such as PowerPoint slides.
The Lync user interface is customized for each device so it better fits expectations of where navigation buttons should be located, for example.
The client for Windows 8 devices such as laptops and tablets offers additional features such as live tiles -- colorful squares that can display pictures of contacts that alternate with a display of their presence status.
The client features People cards that supply a range of information about each contact like who they work for and what work team they belong to so if an individual is unavailable it is easy to figure out how to contact a colleague.
With Windows 8 it is also possible to click on a meeting notification in the Calendar application and immediately join the meeting. (There was a glitch with the demo of this feature because the microphone on the machine was being used by another application.)
With the latest version of Lync participant machines can join and each machine will produce audio and video at the highest resolution each participating machine can support. Previous Lync versions would give uniform resolution based on whatever the lowest common denominator codec was.
This is by virtue of a new codec being used in Lync, H.264 SVC. This codec requires less server-side translation of formats, making for more hardware efficiency.
Part of the demonstration was done on a Macintosh via its Safari browser using the new Lync Web client plug-in.
The mobile iOS client is due out at the end of March. The Android client is due a month later, Microsoft says.
