how can you set up Google voice where you can "switch on and off" the Google voice number from your phone? In other words, it goes like this: you sign up for a Google Voice account and you get a phone number to go with it..let's say you have your own business and you want to keep your personal number separate from your business number. Let's also say that during the hours of 9-5, Monday through Friday that's the time you take care of your business including business related calls; so you "turn on" your Google Voice number to communicate with your clients during the week. All incoming calls from your business clients go to your phone (which is the same phone where you can take personal calls from your personal number) using your Google Voice number as well as all outgoing calls having your business number show up on your business client's caller ID; you don't want them to know your personal number…then on the weekends because you want to deal only with family and friends and nothing business related you want to "turn off" your Google Voice number where if anyone tried to call your business number it would go to voicemail or they wouldn't be able to reach you until Monday when you "turn on" your business phone number. Is there a way to do this?
