Asterisk Voicemail configuration

I have been able to install Asterisk version 1.4 (PBX In A Flash), but I have been unable to get voicemail to run… it ends with ‘the person you wish to contact is unavailable’ message.

Here are the parms I’m using:

;extensions.conf

;this is where parked calls go if they time-out. Should probably re-ring
