I've seen various articles about Advanced Communication SKU and they all seem circuitous and ultimately referring to Microsoft's own announcement.
One of these features is something being called "Teams Calling", which is described as "With Teams Calling, a cloud-based phone system, employees can continue to do this whether they are in the office, working from home, or some combination of the two."
I am wondering how is this different than MS Phone System that's currently available? Is this an automatic 'entitlement' that's part of the Advanced Communication SKU if you choose to add it (ala Azure AD Premium comes as part of EM+S). Or is it just re-branding?
