Sure, I understood his point. No this is not over VPN.

Lync works just fine, no problem, until I refresh a few pages in Chrome, the audio breaks up.

Some HTTP traffic should not cause a break up of audio on Lync. I have a ticket open with PN about this which is being handled.

Regardless of package, VOIP is Titanium and should always be the highest priority compared to a little bit of HTTP traffic created by load a web page. The OP expressed a concern about the traffic management, it is clear it is not quite right.

The same problem exists with Lync and WebEx.
