Microsoft today updated their Lync app for iPhone and iPhone that includes new Gallery View for the iPad, Lobby Control and promote/demote participants for both iPad and iPhone. You can have up to four video streams in a Lync Meeting on the iPad. Lync automatically detects and shows the video streams of the most active speakers in the meeting. With the new Gallery View on the iPad, and the four live video streams, you can now feel the same wonderful experience you have on the Desktop and on Lync for Windows 8.
Apart from this, Microsoft has added couple of features for managing meeting attendees.
In this update, a presenter with Lync 2013 for iOS will receive a notification that there are new people in the lobby waiting to join the meeting. After opening the roster, a mobile presenter is able to either admit or deny people that sit in the virtual lobby. Click here to learn more about the virtual lobby in Lync Meetings.
Lync gives users a flexible and controlled environment. With this update, we are improving meeting management by enabling the Lync Meeting presenter to promote any participant from an attendee status to a presenter status during the course of a Lync Meeting. The same applies to demoting a presenter to an attendee status.
