Telify is a Firefox add-on that recognizes phone numbers on web pages and converts them into clickable links, it can turn telephone numbers into clickable links for use with CTI applications, SIP clients, Skype, Netmeeting, snom phones and the AGFEO TK-Suite Client.

This works with many CTI applications, SIP clients, Skype, Netmeeting, snom phones and the AGFEO TK-Suite client. In general, all telephony software, devices or interfaces which can be controlled by a calling a URL, will most likely enable you to call a phone number directly from your browser.
This is done by passing the phone number to the configured system protocol handler and from there to the software which registered this protocol handler. Just like an URL starting with "http", a link can also start with other protocol handlers, e.g. "tel", "sip" or "skype".

Applications like Skype or X-Lite register an appropriate protocol handler in the system upon installation. So after installing Skype and using an URL starting with the protocol handler "skype", a phone number can be called directly from the browser.
