Call Recordings Maintenance
- Convert WAV to MP3
  - Reduce the file size
- Move recordings
  - Move the recording from the source to a destination directory.

At the top of the file need to define or set the destination_directory...

In my case I put the file in /usr/src and then run manually like this.
/usr/bin/php /usr/src/fusionpbx-install.sh/debian/resources/maintenance/call_recordings.php

Debian
crontab -e
0 * * * * /usr/bin/php /usr/src/fusionpbx-install.sh/debian/resources/maintenance/call_recordings.php > /dev/null 2>&1
