Find mailboxes that haven't set up a greeting or name

Do any of you know of a way for me to report on which mailboxes haven’t set up their name and/or greeting yet?

Thank you!
Roger

These are saved as fixed filenames, which you can enumerate with:

# find /var/spool/asterisk/voicemail/*/*/greet.wav
/var/spool/asterisk/voicemail/default/6006/greet.wav
/var/spool/asterisk/voicemail/default/6008/greet.wav

Awesome - thanks, much!
