[Asterisk-Users] Auto callout - reminder - is it possible?

[Roger Hanson]

I'm trying to get a script working on a website to send out automatic 
email reminders to customers reminding them monthly to change furnace 
filters.  I haven't got one running successfully, yet.

That made me think - could it be done with a phone call using Asterisk? 
A monthly automated phone call to remind people to change their furnace 
filter?

I have no ability to figure this out myself, but can it be done?  Has it 
been done?  Can I just search for an Asterisk application to do it and 
customize it for my own use?
