Well, yes, if you invoke a new instance of the script each time, that is 
what would happen.  The desired approach is to have some means of 
communicating with the running daemon to indicate to it that it should 
originate a call, perhaps via a control socket/API.

If your invocation is in the dial plan, the simplest thing to do would 
be to build a FastAGI server in Perl.  This CPAN module can save some work:

 
http://search.cpan.org/~jaywhy/Asterisk-FastAGI-0.02/lib/Asterisk/FastAGI.pm

Then have that process either maintain a persistent AMI connection, or 
open a new one each time if you don't feel like/don't know how to 
implement the asynchronous approach.

When you want to initiate a dial, just call:

    exten => ...,x,AGI(agi://some.server.ip/your_script)

Of course, you could also use call files if the script is executing on 
the same Asterisk server as the one on which the dials take place.
