We covered Google's Click to Call feature which adds an image of a phone next to an AdWords ad and gets users in touch with advertisers on Google's dime. In a Google Groups thread, a new advertiser is eager to sign up.
Unfortunately, however, she is unable to.
AdWordsPro writes in to say that Google is not accepting any new advertisers for the time being.
I am sorry to say that the click-to-call program is not accepting new advertisers at this point - and I am not yet aware of when this might change.
Forum discussion continues at Google Groups.

This project dates back quite a bit and still only available to a controlled group. I wonder if its not working out as planned.

It looks like Google threw this out. Chances are they realized that people who place a call are less likely to click on the next ad as well (typical for PPC).
