Check out efax.com.
It costs me $10 a month, and I have a private fax phone with that. efax then converts all incoming faxes to emails and sends them on to my email. I can view all faxes before printing, I can save them to the hard drive, I can insert a fax into a report as a digital product, no out of paper condition, no jammed paper situations...and you delete the garbage faxes. Got rid of our 2nd phone line that was for nothing but the fax machine.
Now our fax is plugged into the regular phone line...but is only powered up when we want to send out a fax.
There are also a couple of other companies doing about the same thing as efax.
