Hello Team, I'm bumping this thread again, trying to find a solution to this continuing issue. Chuck, you stated that you cannot assign a caller ID to a number that is already associated with a different "user" extension. This is why it does not show up under the list of numbers to select Caller ID. Only "Company Number", "Blocked", "Main Number" or "Additional Number" are available options. "Additional Numbers" are only numbers not currently assigned to extensions in the account. IF the desired functionality isn't available, does RC allow for more than one "Company Number" per RC account? Can we add additional numbers to be "Company Numbers"? Or is there only one Company Number per RC account allowed?
