If you are interested in click-to-call using the RingCentral softphone, it appears you can set up GoldMine to create phone number links using the "callto" URI scheme which, when clicked, will auto-dial the number using the RingCentral softphone when configured to do so by the OS.
Does the above fit your use case? If not, can you provide more information on what you would like to accomplish with GoldMine?
