Description (partial)

Symptom:
The ms-lync-video is being recognized as rtp in protocol-pack v8 and above.

Conditions:
When a point-to-point audio or video call is switched to a conference call (with a Lync server as the conference bridge) then NBAR2 no longer identifies the packets as ms-lync-video or ms-lync-audio and identifies both of them as rtp.
