Dial Ring Group using Command line and batch file

I have a ring group setup to ring a set of classrooms. I’d like to be able to put a command line into a batch file and set it as a schedule task so we can ring the classrooms on a schedule. I tried a few things, but I think I’m missing something.
Thanks

look into adding asterisk call files into /var/spool/asterisk/outgoing “touched” with when you want the call to happen.

Paging Pro…

What do you mean by adding call files “touched with” Can you post a sample call file or direct me where to edit or create them?
Thanks

To do this in Windows, I use nice little utility provided for free by tttelecom:
http://www.tttelecom.nl/index.php/en/products/adat
I mainly use it for phoning from webpages, but I recently discovered that it supports dial commands from a dos prompt.
I use it in a batch file executed by my cctv system: when a camera sensor is triggered, it calls an intercom unit situated close by.

This .bat dials extension 1123:

cd C:\Program Files\TTTelecom\ADAT
adat.exe 1123
exit

Can´t get much simpler than that…
