deleting a predicatable name in /tmp without verifying first it has
existed exposes you to a symlink attack. Not that big a threat, but
somrthjing to be avoided if it's not too big an issue.

This is probably /usr/share/asterisk/sounds/102ivrrecording.wav , which
should not be writable.

Indeed, there is no reason for you to modify most of the sounds. They
should reside on the flash. Maybe have sounds/rw that will be a symlink
or bind-mounted?

My current 'record' extension:

exten => 210,1,Record(/usr/share/asterisk/sounds/voicemail/rec:gsm)
exten => 210,2,Playback(voicemail/rec)

Where exactly is the database stored?

There are better and safer ways to allow the user to reboot. A mysql
database does not strike me as the best way to ensure that goal.
