Hello. I just noticed in my O365 Message Center an article saying that the Skype for Business Online Plan 2 standalone licenses are being retired. I use several Real Presence Trios and a few Group Series 310s and each of them have the Skype for Business Online Plan 2 license, Domestic Calling Plan license, Exchange Online Plan 2 license and a Phone System license. It looks like we're going to need a Business Essentials or Business Premium license, which include a lot of features that the Polycom devices don't need. I just wanted to check and see what everyone was planning to use when the Skype licenses are retired.
The newer Meeting Room license is what you should be using as it'll still include SfB Online capabilities. Only the standalone SfB Online license SKU is going away as to push everyone to use a license which includes SfB Online and Teams.
