Incoming Faxes

Warner cable wants to charge me $29.95 for a simply fax line, no add ons included. As I remember several years ago I had a fax program where the incoming fax arrived on my computer and I printed it out. It was very simply and very easy. At that time I had a phone line for the internet connection. Now I have a cable connection. Is there a fax program available to do the same with cable? I would like to get rid of that separate fax line.
