What I'll probably do is get another number with a distinctive ring added to my current line ("Identi-Call"), which is a bit less expensive than getting another separate line. I do have a gizmo called "the Ring Selector" that could screen out non-fax calls to the line that goes to the modem, provided I have Identi-Call. Still, I was hoping to not have to add another monthly charge to my expenses. Ah well. I did get rid of voice mail when I found an old cassette-tape answering machine in a used electronics shop. Works great. But I don't see a way around this issue, except for just having one number and telling people to call me first before faxing (which, actually, may be fine).
