I have the GE phone set where I have the main phone with an answering machine then 2 extra hand sets. they have a google button if you are in to that. Each phone has caller ID, call waiting ID, and all the other things you could want. I love the phones except that they are all cordless so if the power goes out - no phone -  I keep pone of the handsets next to the couch in the living room  and then put the other hand set in the bathroom - never know when you need that phone. My only problem with this system is that the main set rings before the handsets start, then they ring together. No biggie....
