Merge all of your various cell phones, home phone, and office to a single number using Google’s free GrandCentral. GrandCentral’s interface gives you the ability to screen calls, setup different ring tones for different phone numbers, and block callers.
GrandCentral can also be setup up to have all of your voicemails arrive at a single inbox that sends an SMS or email each time a message is received. Also you can setup up an account so Web users can call through the Internet. Similar to Skype, you can route international and long distance calls to a single number for free.
