HumbleFax is an unlimited online faxing service that makes your fax machine obsolete. You can use a real dedicated phone number to receive faxes into your email inbox and send faxes by attaching your documents (such as PDF or .DOC) to an email. HumbleFax was designed from the ground up for simplicity and ease of use.
Humblefax is a great solution for faxing. I changed my number to a local one to save money on long distance calls and to eliminate the possibility of spam appearing in my caller ID. Humblefax delivers incoming received faxes as pdf files, so there is no loss of image quality. The price is very reasonable.
