In order to track cell phone calls produced from your website in Google Analytics and Google Adwords, first place this code around the phone number:
<a href="call.html">914123456</a>
2. In the file call.html, insert in this order:
a. Your Google Analytics code (main code + event for tracking this call).
b. Your conversion code from Google Adwords.
c. This special code, which automatically will perform the call:
<script type="text/javascript">
window.location = 'tel:914123456';
</script>
Once the user clicks on the button, the Google Analytics and Google Adwords codes will be triggered, and then the cell phone call will be automatically performed. This will only work in smartphones with full browsers. Try it from here with your cell phone:

If you would like to track cell phone calls with greater precision, including users which actually are visiting your website from PC browsers, please read the article
"How to Create a Phone for Adwords". This solution can be applied selectively to different traffic sources.
ATTENTION: don't use onclick events to track cell phone calls.
Some cellphones may show this flawed number after the user tries to call. Therefore, preferably use intermediate pages with all the needed codes to track and execute the call.
