Google Voice is a service where you can get one local number and have it set to ring all your phones. This is great if you have a home, work and cell phone because you can give one number and have it ring everywhere. You can also have voicemails transcribed to text and emailed to you as well as have your text messages emailed to you. Also you can schedule it to ring certain phone numbers at certain times! This is perfect if you don’t already have a well known number because then you can give everyone you know one number and then when you recieve calls, you can pick up on whatever phone is convenient for you. You can also replace your cell phone voicemail with Google Voicemail giving you a centralized voicemail box that can be accessed over the internet. I think it will be a great way to centralize all you phones and just to get one number to ring them all. One downside though is because it is still a semi new product, it is invitation only but, if you can get an invitation, theyn give it a try to have one number to ring al your phones!
