There are three workloads provided under the Microsoft Teams banner which can be deployed independently of one another if required. This allows businesses to have more control over the features they enable or disable – for example, you may want to restrict Teams from being able to call out if you already have an existing phone system in place. The three workloads are: 1. Chat, Teams and Channels 2. Meetings and Conferencing 3. Phone System (Microsoft 365 Business Voice) and PSTN Connectivity
