[Freeswitch-users] Call Recording file format(s)

[Michael Collins]

All things being equal, we just save as a wav and then do post-processing
to convert it to the flavor du jour desired by the end users. One advantage
of doing this is that you have the option of off-loading the file
post-processing to another system if you so choose. Between sox and lame
you've got all the free tools you need to convert to whatever file format
your circumstances dictate.
