I want to be able to make click-2-dial from within the webmail interface.

I know it is possible in the Contacts tab as you can add a new button within a contact's details. Then, when you click on that particular button, you can automatically grab the contact's phone number and call a click-2-dial function.

However, is it possible to do the same with regular expression that would be recognized everywhere on the web interface ? I mean, is it possible, to recognize that kind of regular expression (+49 322 233 666) and make it clickable automatically ?

Thank you
