HP OfficeJet 7310 - Fax Without Telephone Line With FiOS?

I've got Verizon Triple Play. Basically, my Internet, TV and Phone all come into my house on a Fiber Optic line. Well, I take that back, I don't quite understand what the FiOS Phone really is or how the signaling works.

I have this All-in-One machine, the HP OfficeJet 7310 (link to product information). I hooked it up to my network (printer to router via Ethernet port) the other day and it works great with printing from all of my clients, well the printing does. I haven't tried the scanning portion, yet but I would assume it works just fine. What I didn't hook up, is a phone line to it. I wanted to know if there's a way to fax through my network, thus eliminating the need for a telephone connection. I figured there COULD be a way, if my Phone at some point came through the Fiber Optic.
