GrandCentral is a service purchased by Google in July 2007 that simplifies your phone usage by giving you one centralized phone number that will ring all of your phones at once.

In this day and age, it’s not unusual to have a cell phone, work phone, home phone and who knows how many others, making it difficult for people to know which number to call to find you at.  GrandCentral will let you set up a free account that gives you a virtual phone number that will ring up to six phone numbers at the same time when someone calls it.  You can also enable and disable numbers as you see fit so if there is a number you don’t want ringing at a certain time, all you need to do is uncheck it.

While this may not seem that exciting, there are some other interesting bonuses such as free voice mail and the ability to record calls when someone calls into your number by simply hitting one button.  When you do have a voice mail, you will receive an email letting you know, and you can then listen to it on your computer or via the phone.

For now the service is free and in beta, and there is no clue when, or if, they will begin charging, but for now it is a fabulous service everyone with more than one phone should be trying out.
