We are a small business and want to use Trio 8800 in our conference rooms with Skype for Business.
We don't have Skype for Business today. On Microsoft there is the Enterprise plans: E1, E3 and E5 plans. But there is also Small Business Plans: https://products.office.com/en-us/compare-all-microsoft-office-products?tab=2
Does the "Office 365 Business Premium" plan work with Trio 8800?
