[Freeswitch-users] setting recording codec

[Stanislav Sinyagin]

as far as I understand, FreeSWITCH chooses the WAV parameters which
are matching the current channel sampling frequency and codec. For
example, if you record a G722 call, you would get a 16kHZ WAV file.

Forcing it into one specific encoding would add real-time CPU load. I
think it's still more preferable to run a post-processing job in low
priority -- this way you ensure that the ongoing calls get the best
serving.

You can easily catch the event of call ending and trigger the
conversion job, by listening to the events via ESL connection.
