asterisk users - Apr 2010 - dial extension and play sound file from shell on asterisk server?

I want to use Asterisk as a general message delivery system here.

That is, I want to be able to have a (shell, perl, etc.) script on my
Asterisk server dial an extension, wait for it to be answered and then
play a sound file and then hang up, or even wait for a response or
reactions to some IVR.

Certainly if I had a SIP library, I could have the script simply look
like a SIP extension but that seems like it should be an unnecessary
added complication.  Instead I am looking for a more direct API to
Asterisk which allows a process to interact like a "phone" but not
actually be one.

Is this at all possible?  Anyone done anything like this?

b.

# asterisk -rx 'help channel originate'
  There are two ways to use this command. A call can be originated between a
channel and a specific application, or between a channel and an extension in
the dialplan. This is similar to call files or the manager originate action.
Calls originated with this command are given a timeout of 30 seconds.

Usage1: channel originate <tech/data> application <appname>
[appdata]
  This will originate a call between the specified channel tech/data and the
given application. Arguments to the application are optional. If the given
arguments to the application include spaces, all of the arguments to the
application need to be placed in quotation marks.

Usage2: channel originate <tech/data> extension [exten@][context]
  This will originate a call between the specified channel tech/data and the
given extension. If no context is specified, the 'default' context will
be
used. If no extension is given, the 's' extension will be used.

See cli_permissions.conf (or whatever it is called) if you want to allow
other users to use that command. Note that it allows such a user to do
practically anything as the user running Asterisk.

AGI and AMI is what you need for this.

AMI is for originating the call between extensions
AGI for playing file of your choice.

Both these APIs are well documented
