ActFax and Web Fax Providers
ActFax can not just be used with traditional analog and ISDN phone lines or VoIP/FoIP. As an alternative, using ActFax in combination with a Web Fax Provider would be a very easy and economic way to connect the fax server to the public switched telephone network.
The connection between the fax server and the Web Fax Provider is done through a normal encrypted Internet connection. The fax data is submitted in digital format, which makes the connection immune to transmission failures (this often is a major issue with Voice over IP connections). The setup of the fax server is very simple when using a Web Fax Provider; you typically just need to enter the login and password of your account in ActFax (see screenshot of the menu Communication / Web Fax Service on the fax server). ActFax supports the Web Fax Providers PC-Fax.com, InterFax, Phaxio and ConcordFax.
