In a previous blog post, the ability to use Skype for Business certified IP Phones in a Teams environment was discussed and how users who have migrated from Skype for Business to Teams can continue to use these IP phones to make and receive calls. In this post, we continue the discussion and provide an overview of how Teams users can be enable for enterprise voice. Unlike its predecessor, Teams is a pure cloud service and there are no on-premise Teams servers, and hence majority of the Voice configurations have to be performed in the O365 tenant using powershell. Our tenant has a E5 license which enables the Phone System (formely CloudPBX) feature for this to work, but E1/E3 users can also be enabled via the Add-on license |
