How to make a call from a computer through a telephone line?

Question

Telephony

I have a regular analog telephone line that I don't pay for.
But for calls, I use a paid Skype subscription, because. I like free hands and the ability to call by dialing a number on the keyboard, use the numbers saved in the address book.
