Google/Windows Live Maps' Click-to-Call

Okay, this is very cool:

Google Maps. Look up a business. You'll see a "Call" hyperlink next to the business' phone number. Click that. Enter your telephone number. The service will call your phone. It will then call the business' phone, and voila -- you're connected. Free. Very cool. And a lot of fun.

Some additional information here.

Windows Live Local. Look up a business. You'll see a "Call for Free" hyperlink next to the business' phone number. Click that. Enter your telephone number. The service will call your phone. It will then call the business' phone, and voila -- you're connected. Free. Very cool. And a lot of fun.

I believe Windows Live was actually first out the gate with this technology, but Google's gotten a little more attention on it, I believe. Either service works very well, and it's a great service.
