Callto:// dialing ordinary phone without VoIP at all?

Hi all,

this is what i am looking for:

Click a callto:// URL on my PC and my ordinary phone dials the number and conects, just like I entered the number myself into the phone.

What hardware/software do I need?
This is for a singel person, 1 ordinary telephone line, Windows XP.

Btw. VoIP is no option. :frowning:

Thanks for your suggestions.
