Thanks!

I could configure the ATAs to "auto-dial" a custom "destination" which would then call the command Pickup() passing it the appropriate parameters by checking the CallerID. After the Pickup() cmd has been executed I would call DISA without a password.

There could be security issues of course. The only "check" I would do is based on the caller's ID (basically the extension number).

Can a caller ID be spoofed? What other filtering logic can be applied for dialplan security?
I've read this doc:
http://www.voip-info.org/wiki/view/Asterisk+security+dialplan
but is there more information elsewhere?
