I had a question about the chart showing the license usage in various scenarions with Lync. Specifically slide number 26.
Under Encrypted B2B (SIP SIP call without AMG) it states Two Non Traversal. However I have another slide from Cisco attached and while it is for a single VCS and I know your scenario has two VCS (one for internal video end points and one for Lync), where for the same scenario it shows 1 Traversal. That is because the media has to be forked through VCS even through it is SIP to SIP. So if I use the same analogy for your scenario, it should be 1 Traversal and 1 Non Traversal.
I realize that normally under SIP to SIP calls it should be Non Traversal however when the media is encrypted, the media is forked through VCS consuming traversal. So in your case with 2 VCS, the first Lync gateway VCS should consume traversal and the second VCS should be Non Traversal.
Can you please clarify license usage?
