Meeting rooms in Vectera are by default locked - meaning your clients can’t enter without you being present. Guests will have to knock to enter the room (with our without showing camera) and the host can accept or deny access.

You can manually invite clients to the meeting room to have all time access to the meeting room. In their invitation they will be sent an access key (in the URL, they just have to open/copy paste the URL) and they will be allowed to enter without you being available.
