Hi @IBN
Do you mean you want to schedule video conference in Teams client?
Based on my experience, video conference do not need the license. If people in your organization need to use a phone to call in to a meeting, you should get it from:
- Try it before you buy it: you can sign up for an Office 365 Enterprise E5 free trial that includes Audio Conferencing. See Office 365 Enterprise E5 Trial.
- Buy it: see Microsoft Teams add-on licensing.
