Nick,
Could you clarify your point of being able to over provision here? From my
experience, as you add sessions to one service, it dynamically reduces the
available sessions on the other services.
I.e., If you do a ? on sessions for transcoding, it might say <1-40>. But
if you go and add a few more conferencing sessions first, and come back, it
will be lower. Say <1-32>. I'm making these numbers up, but the fact
remains, the maximum number you can type in, is limited by the available
resources at config time.
Thanks for sharing. I look forward to your response.
