Digium Fax For Asterisk

Digium Fax For Asterisk (FFA) was developed out of a strong desire from the Asterisk community to have a Digium-supported fax mechanism in Asterisk. Free for single-channel use, this product can also be licensed from Digium to handle more than one simultaneous fax channel.

Obtaining Digium FFA

Digium FFA can be obtained from the Digium website (http://www.digium.com). The process of downloading, installing, and registering this library is thoroughly documented in the Fax For Asterisk Administrator Manual, which you can also download from Digium. You will need to register at the Digium website in order to obtain your free single-channel fax license key and download the admin manual. There is also a comprehensive README file included with the software, which details the steps necessary to get Digium FFA going on your system.

Disabling Digium FFA (Should You Want to Test spandsp)

The Digium FFA library and the spandsp library are mutually exclusive. If you want to try out spandsp, you will need to ensure that Digium FFA does not load. To disable FFA, simply edit your /etc/asterisk/modules.conf file as follows:

noload => res_fax_digium.so

Save the changes and restart Asterisk.
