We use the same bridge number for all of out meetings that we have since day 1 with RC. There needs to be an option in the settings for the plug in to set your own meeting ID
Tom - RingCentral Meetings always generates a new Meeting ID with each new meeting. The standard host bridge is for RingCentral Conference calling which is a different product.
You can use your bridge as a 3rd party audio and enable 3rd party numbers for meetings as the admin and all scheduled meetings moving forward will have your bridge number and participant code for the audio.
