Internet faxing services can be divided into three groups, each of which has a different usage pattern and volume requirement. The three groups are:
Home User or SOHO* User - These are typically low volume users. They need to send or receive faxes only occasionally, and might prefer not to pay a monthly subscription to get service. If you're in this group, you may want to look at providers like eFax and Callwave.

Your DSL / ADSL / ISDN / cable broadband internet connection will normally be a data connection to which you are connected with a data modem (not data/fax modem). This means that you can only send and receive data from your internet service provider (ISP) on this line, and cannot send and receive faxes*.
