You can use Powow with any teleconference application that includes a dial-in. Unlike other conference call providers, Microsoft Teams allows a connection by a URL without a dial-in if Powow Adapter Lite is enabled in your Organization.
For the most common teleconference apps, all you need to do is add firstname.lastname@example.org to the invitee list on your calendar invite. Powow supports several meeting invite formats “out of the box”, including Zoom, WebEx, Google Meet / Hangouts. For any other application, it is possible to add Powow dial-in information to the meeting invite using a few simple lines in the meeting description.
More details on how to invite Powow to your meeting, you will find here.
