Fax Software

Does any one know any good fax softwares out there. These softwares let you send/receive fax using ur computer when it is connected to a landline/fax phone line. I have used a fax software in the past but I cant recall its name. I just downloaded 'Essentialfax' ...this software looks good but I cant seem to send faxes which consist of more than one pages.

Any one out there uses fax softwares or know any good ones?
Thanks so much

 

I used EFax a few year ago the gave me my own phone number which was assigned to my computer. If I can remember it was ok.
