Faxing from win xp: I've set up xp to send faxes HOWEVER, my only access is throigh the sprint wireless web connection card- We cut the land line months ago. Everything seems to work except I get an error signal " o dial tone detected" Anyone have experience with this?

Is it true, do I have to drop back to windows 95 and microsoft fax if I want to fax from my computer. We've cut the land line and are all wireless (thank you Sprint wireless web) but cannot get beyond the fax console.
