Teramind has a dedicated Online Meetings report that captures meetings/conference calls on popular apps such as Zoom, Microsoft Teams, Webex, etc. You can view who participated in the meeting, when, for how long, etc. You can view the recordings of the meetings and chat conversations that took place.
You can also use the Applications & Websites BI report to conduct detailed analysis of these apps.
You can create app/web rules. For example, get notified when one of these apps is used for a certain amount of time. Or, if a user/department is spending too much time on meetings compared to other users/departments.
