Google’s new Google Voice, created a couple of years after they purchased GrandCentral, may create another alternative for small businesses looking to reduce telecommunication costs. One feature that will help businesses eliminate some business phone numbers is that Google Voice allows different voice mail greetings depending on the caller’s phone number. So you can have a business greeting for your clients and a personal greeting for personal contacts, all on the same phone.
