I was able to achieve this! I modified the extension to do so. In the file content_script.js I added the following code to execute right before the page is parsed:

$('a[href*="callto"]').each( function() {
            var link = $(this), newUrl = link.attr('href').replace(/^callto:/,'sip:'), phoneNumber = newUrl.replace(/sip:/, '');
            link.attr('href', newUrl);
            link.attr('rel', phoneNumber);
            link.addClass('fop2-click-to-call');
        });

It would be great if you can add this to the extension so I don't have to modify it every time I update. But if not, it's fine too!

Hi,

My particular CRM links to numbers automatically by inserting a link (normal <a> tag) to the target callto:phone#. For example:

<a href="callto:555-555-1212">link</a>

This would make sense to be clickable in Chrome, but instead it fails to recognize it as a number.

What would it take to register the click-handler with the extension? It wouldn't happen to be open-source somewhere so I can fix it, would it?

Thanks,
Daniel Jabbour
