[asterisk-users] looking for a way to do appointment reminders

[jg]

Hi Brandon!

I have a "wakeup call" system based on "call files" that are generated 
by an external C program. The call files can be triggered by dialing a 
phone number (e.g. for waking up the hotel guest in room 333 at 6:15 am: 
*77*3330615) or from outside via a web interface, or whatever.

It looks like your task has the same basic requirements. Setting up a 
call file based system is not very difficult, but details like 
pronunciation of the guest's or patient's name may involve some 
additional work.
