Disabling spandsp (Should You Want to Test Digium Fax)

terisk/modules.conf file as follows:
noload => res_fax_spandsp.so
Save the changes and restart Asterisk.
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 documen-
ted 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 com-
prehensive README file included with the software, which details the steps necessary
to get Digium FFA going on your system.
