Google's GrandCentral, a Personal Online Communication Center

GrandCentral is a unique service that is available online to manage all your telephone numbers in one place. Once you become a member of GrandCentral, it assigns you a personal phone number, which you can use it for life. GrandCentral calls it One Number...for LifeTM - a number that's not tied to a phone or a location - but tied to you. So, you can give this number to anyone and don't worry about getting Spam Calls, which you can easily block it at GrandCentral. Google purchased GrandCentral today, so you will see more features added to it free or for a small service fee. But for now it is free.

So, if you have a mobile phone, office phone, home phone, instead of getting the messages lost or which number you should focus more, you can just give one phone number to everyone. With that phone number, the callers can leave a message for you to return the call. GrandCentral either calls your main phone number (Stored in GrandCentral account) and connects you to the person or notifies you via e-mail about the call you received, so you can answer by screening the calls. This message is recorded and is available online in your GrandCentral Account online. You can either save it or delete it. There is a "call" button after the message, so when you want to talk the person, GrandCentral connects you (wherever you are) to the person that left a message.
