If you would like to be able to assign an Alternative Host while scheduling an RC Meeting, please vote!
Just chiming back in on this post, we have now gone live with RingCentral at our Corporate office (about 125 lines) and I have had 4-5 individuals in the first week ask me about this feature. We will be migrating away from GoToMeeting which considers this "Co-Organizer". As previously mentioned, this functionality is already available in the zoom product - called "Alternative Host". I have to believe with 119 up votes that this would be something that would be being discussed on the road map. Any updates from the Ring Central side?
