Did you know that Google AdWords has a feature/extension named click to call? Yea, I did also.
Did you know that Google charges just for a user clicking on the number, even if they don't press the "send" button or even if the call does not go through? I did, but seems like some advertisers did not know that.
Google charges for clicks on the phone number, the same price (I believe) as you would pay if someone clicked on the ad and went to your web site.
Does Google charge for users who click on your ad and for some reason do not end up on your web site? I.e. your site is down temporarily or hacked?
Yes.
Does Google charge for users who click on your phone number but don't end up ending up speaking to someone at your company?
Yes.
Same logic.
The question came up at a Google AdWords Help thread where Google AdWords representative Wyatt explained the documentation:
Remember that for mobile devices, a click-to-call is reported as soon as the customer clicks to call your phone number, regardless of whether or not the call is completed.
Is this fair?
