Google Click-to-Call was a service provided by Google which allowed users to call advertisers straight from Google search results pages. Users entered their phone numbers and Google would connect the call to the advertiser. Google paid for the calling charges. The service was discontinued in 2007.  For some time, similar click-to-call functionality was available for results in Google Maps. In the Froyo release of Google’s Android operating system, certain advertisements included a very similar functionality. In iOS, phone numbers are automatically recognized as such. Web developers can also provide direct links to the Phone application, providing similar functionality.

Google now offers a mobile click-to-call function which allows searchers to call a business directly rather than going to their website.
