What would it take to move the logic into Asterisk?
(1) is naturally trivial. As for sending the actual signal to open and
close the door: that may take a separate out-of-band operation. e.g.
System(/usr/sbin/open-sesame)
But what about typing the PIN?
"Hello, you have reached Treasure Cave Inc. If you know the access code,
dial it now. If not, press 0 for the operator."
The point is to separate communication from door opening. Both are
different problems to solve. I'm not sure you will gain much by
bundeling them together.
