I believe you'll have to contact your operator about Fax support.
You need to contact your service provider and they need to activate data and fax on your line. They will then issue you with 3 numbers. 2x data number and 1x fax number. You give the fax number out to people and as long as your phone is on and has coverage faxes will come directly to it.
What I do though when it comes to faxes, is I give people my faxmail number which is always available and when I receive a fax and I dial into my faxmail and forward the fax to my 9500 fax number.
