Problem: I use my iPhone (Vodafone account) for personal use and for the two businesses that I run.  When somebody calls, I can't tell if they are trying to reach me personally or one of the businesses, so have to just answer with my name and try (often unsuccessfully) to guess what/who they want.

Question: is there a service out that there that could provide a virtual phone number for each of the businesses AND let me know through caller ID or even just a distinguishing phone number that I could store in my phone, which business an incoming call is for?

TIA
