This is what Google FAQ says on "Click to Call" project. Revolutionary idea again from Google.. !! I think this will open new horizons in advertisement arena..
- What's the phone icon on Google search results? How does it work?
We're testing a new product that gives you a free and fast way to speak directly to the advertiser you found on a Google search results page - over the phone.
Here's how it works: When you click the phone icon, you'll be invited to enter your phone number. Once you click 'Connect For Free,' Google calls the number you provided. When you pick up, you hear ringing on the other end as Google connects you to the other party. When they answer, you simply talk normally as you would with any other call. - Who will get my phone number?
Google uses the phone number you enter just once, to make the automatic connection between you and the advertiser. Your number is blocked so that the advertiser can't see it. Google doesn't share your number with the advertiser, and we won't use the number to make any other calls to you. In addition, your information will be deleted from our servers after a period reasonably necessary to operate the service. We take your privacy very seriously.
- Whose caller ID do I see when connected?
The advertiser's number appears on your caller ID when Google connects you. This way, you can save the merchant's number for future call-backs.
- Am I charged to connect to an advertiser?
No. Google foots the bill for all calls, both local and long-distance. However, if you give us a mobile phone number, your normal airtime fees or other fees charged by your provider for the call may apply.
This is how it looks like..
Keep it up google !!
