MediaLineLabel in Lync 2013 QoE


The MediaLine table in the Lync 2013 and Skype for Business 2015 QoE database contains a column called MediaLineLabel. The label specifies the media type related to the MediaLine. In Lync 2010 you have been used to seeing the values 0, 1 and 2 in the column. However in Lync 2013 you might find the additional values 3, 4, 5, 6, 7 and 8. In addition in Skype for Business Server 2015 the additional value 16 was added. What does these values specify?

I have shown it in the table below. The new additions are 3 for application sharing, 4 – 8 for gallery view video and 16 for Video based Screen Sharing (VbSS). The Lync 2013 and Skype for Business 2015 clients supports up to 5 video streams in the gallery view and that is why we have the values 4 – 8. Video based Screen Sharing (VbSS) is a new feature in Skype for Business 2016 client available for peer to peer calls.
