Mobile users should not affect how the RC Meetings or RingCentral Video works. It depends on the service subscription.

RingCentral Meetings has a 40-minute limit for those stand-alone or free accounts, while RingCentral Video has no time limits but will automatically end after 24 hours. You may check the links below for reference with RC Meetings and RCV.
