Hi Alice
Thanks for the reply. I have seen that link, several times.
Site Topologies
Your deployment must include at least one central site, and can include zero to
many branch sites. Each branch site is affiliated with one central site. The central site provides the Lync Server services to the branch site that are not hosted locally at the branch site, such as presence and
conferencing
What defines "many" 10, 16, 35, 100, 200?
I have opened a support case with DEV and will let you know what I find out.
Thanks
