The mobile device will need to have a browser that "recognises" telephone numbers and have the built-in functionality that when clicking on a number, will start whatever application/process to dial that number. Not much you can do from an HTML perspective...
Thanks. I see what you mean. Two more questions pertaining to mobile devices: 1) Is there a script or something that can tell if the visitor is using a mobile device and send them to an alternate website that is built specifically for mobile devices? 2) What pixel width would you suggest to set up a mobile device only website?
Telephone hyperlinks can be used in your site. Although nothing will happen unless the proper software support is available.
Add this meta tag, too.

Depends on which mobile devices you intend to support. Unfortunately, there is no one size fits all. But 320 to 480px wide is customary for iPhones.
