Recoding options for all extensions, queues, and trunks are handled for you in FreePBX.
It sounds like you need to just finish installing FreePBX and set up your extensions. Recording the call can be set for “Force” and everything the extension does will be recorded into the recordings directory.
Just so we’re clear: referencing an esoteric and hard to use specialty option in Asterisk is not the same as learning about VOIP.
Set up the FreePBX system. Set up your extensions. Set them up to record everything. At the end of the call, you should have recordings in the monitor directory that you can access through the CDR module.
