Fax Computer Program

Is there a freeware or very low cost computer program that uses the computer as a fax machine using DSL? :confused:

I use eFax

Free to recieve (with ads), but itโ€™ll cost you if you upgrade to a local number (the number I was given is in Idaho; I live in New York!) or if you want to send.

But if you just need a number to recieve faxes, itโ€™s pretty good.

I use Trust Fax: TrustFax is proud to offer you eFax
