Identifying Incoming Call

I handle more than one business on RC. I currently have multiple numbers set up with different greetings for each number (under custom rules), that reflects the business they are calling. These numbers all ring to my cell but when I pick up I have no clue how to answer the phone. Yes, I can hear it's coming from RC, but I do not have the option to set up separate name announcements to tell me which line is being used, to answer appropriately.
