Fax Without Phone Line How Can I Use My Fax Machine Without A Phone Line?

How can I use my fax machine without a phone line? - fax without phone line

I have an HP all-in-one that can be wirelessly networked. I want to use the fax feature, but I have not a phone line pretty closely. Is there anything that, in combination with the phone jack on the back of the printer, so that they are still used him as a fax machine or I'm firmly with any Internet fax service and only losing the fax in the printer?
