/*

Call Recordings Maintenance
- Convert WAV to MP3
  - Reduce the file size
- Move recordings
  - Move the recording from the source to a destination directory.
  - To move files, you will need to add the destination_path as a setting under category: call_recordings

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

crontab -e
