Call Recording bitrate change.

[chinthaka]

I want to change the bit rate of the call recording files to reduce storage usage. Where can I update the configuration for this?

You can set a channel variable in the dialplan:

<action application="set" data="record_sample_rate=8000"/>

However if all you need to do is reduce storage usage and you are recording in .wav format, then running a cron job to convert your wav files to mp3, may be a better option.
