The issue is not can you execute the same commands from within
extensions.conf, but how are you going to trigger the action without
external input.  

We process calls using the following methodology:

1.Cron starts a job at preset times

2.script log into postgresql and determines if any call are to be made
at this time

3.Script then determines how many calls can be made based on codecs,
time of day, and service provider to be used

4.Script generates call file/s into temporary directory based on above
criteria and moves them to /var/spool/asterisk/outgoing

5.Asterisk places calls, and using cdr_pgsql writes cdr to database

6.upon insert a trigger fires to update list of called numbers and 
indicate success or failure

7.goto 1

Simple process, extensions.conf is used for all call flow, and no
external processes used for updates to database. We used AGi in past and
found that this process was actually easier to maintain as the only
"code" written was a simple php script for db access and call file
generation.


Don't know if this helps with ideas but if you are interested in
additional details contact me off list.
