[Freeswitch-users] setting recording codec

[ik]

In this specific case, I'm using g711, but can have either a-law or u-law
but the service that requires the recording understand only a-law, at the
moment I'm using ffmpeg to convert after the call ended,  and then send it
to that service.

Thanks
Ido
