We use a DoorBird video intercom at our office and also RingCentral. We have this integrated like an IP phone to call a ring group when someone presses the call button on the DoorBird and we can unlock the door by pressing 9 durring a call. The audio works great; however there is no video available. We can always answer the DoorBird using the DoorBird app and see video. It is also nice that the person at the door can leave a message if no one can answer. My request would be to allow an integration with DoorBird that has video during the call.
