I blogged about this last November (http://michaelzimmer.org/2005/11/28/google-click-to-call/), noting the concerns with adding your phone number to the laundry list of personal information Google collects about you.

Run a search for "New York Hotels" (http://www.google.com/search?q=new+york+hotels)and you'll get the little green handset...

Well, only in US/CA I guess, no green phones in good old Europe

If you do the search for [new york hotels] and click the green handset, you can then click "more>>" and see Google's Click-To-Call FAQ. The direct link is here:

Pretty innarestin' that they retain our information only temporarily. From the above linked page:

In addition, we retain your information (including your phone number, date, time, and call length) only temporarily. It will be deleted from our servers after a period reasonably necessary to operate, audit, and evaluate the service.

actaully this is old stuff...and its did not cover my area code even though I was in Canada..

After that I have not tracked this feature...yeah me2 was a little taken aback by the "luandry list" :)-

I get the phone, but it errors when I try to have them call me.

Temporarily still can mean a long time. It just limits Google to a defined time period, as opposed to "forever".

click2call is gone live.. but its like a crank call
