Would like my phone to have multiple phone #s

[TheArtist]

  Ok,  I have the shop, the museum, and my personal phone#.  Would like it so that each one can go to my cell phone and when I look at the phone as it's ringing it tells me which number it is too.  This way I could answer  "DECOPOLIS, may I help you?" or "Tulsa Art Deco Museum" or simply "Hello" if its my personal #.  Would like it so that say the number goes to the shop and to my cell phone at the same time and if someone is at the shop during open hours I can just ignore it and the employees at the shop can pick it up, or if it's a day when we are closed but I still need to get a phone call I can.  And or say if I am out of town and the shop is closed I can still get the calls. The museum also has it's own cell phone and # but the current volunteers haven't' been the best at keeping track of it and are not at the gift shop/visitor center that much so instead of me carrying 2 phones around would again like the # to go to both the museums cell phone and mine, and have a way to tell that the person is calling the museum so I can answer appropriately.

Lots of different services out there that might seem to work.  Any of you ever used one and or know of a good one to use?

I know at&t can do that with landlines, maybe you could have such a landline automatically forwarded to your cell number.
I dont know what the CID would show, though.

You can set up a free number, (one per gmail account) then have it forward to multiple numbers.

Note: It only lets you forward a single phone number to a "cell phone" so if you are going to create multiple numbers like you suggest, just tell it that your cell phone is a land line.

I use and like voice, but, right now might not be the best time to start using it: http://9to5google.com/2014/03/18/google-plans-kill-google-voice-in-months-integrate-features-into-hangouts/

It really depends on how true this is, and how the integration really works. I guess its just a case of being aware that the product you are evaluating is probably going to change soon. No matter what it is fairly clear that GV is not a system google is investing in, it has not been updated in a long time.

Once upon a time I used call forwarding so I didn't have to carry around both my work and personal phones
