Yes. If you have several calls at the same time and cannot attend all, Sembly can handle them for you. It can attend as many meetings as you need simultaneously. You can leave a note to other meeting attendees that you won't be present and that Sembly is here instead of you to record.
If you include Sembly in a meeting, make sure to communicate with the meeting organizer and other attendees so they will admit it from the meeting lobby.
