Asterisk call a number and give them DISA access

I am using centos 4 and asterisk 1.4.1 and i would like to write a script or a context that would allow my asterisk server to call me on my cellphone and give me access to the DISA application.

I tried to do it before, but i am unable to get my server to call my phone and then give me access to the system or another line. I have several lines.

Can anyone help?

Try call files. described in the documents, it works.

Do u mind giving me some more info in regards to call files.

Thanks much appreciated.

In the doc directory the is a file called callfiles.txt which explains it.
