Video conferencing is not limited to 2 participants. Often, several systems and participants need to communicate with each other.
For this, you can either use a bridge service (Teams, Zoom, Visionmcu, ...), or take the whole thing into your own hands with a multipoint license and not leave your own data to anyone else.
With this multipoint license up to 16 systems can be merged.
