Every meeting via RingCentral Video and RingCentral Meetings in the RingCentral app uses a meeting ID. A random ID is created whenever you start an instant meeting or schedule a meeting.
Note: For RingCentral Video, a PMI consists of nine digits for RingEX accounts or 12 digits for RingCentral Video Pro and Pro+ users. A PMI for RingCentral Meetings has 10 digits.
