Just a couple of comments.

I agree with jtodd about the call completion codes, but I'd like to put
this out for some thought as well.

Why is it that Dial is the thing that waits for the call to be
completed?

Why not have dial just dial, then have applications like WaitForAnswer,
WaitForDisconnect etc...?

This would give more granularity to the call flow control and allow
someone to get brave and write a WaitForHuman or whatever.

Or for that matter... since extensions.conf is starting to look like a
scripting language,  Why not embed a perl or Python interpreter into
Asterisk to allow for programming extension logic in whatever your
favorite language is.

Just some food for though.
