Asterisk communication

Hi guys I designed a Andon monitoring system for the company I work for. I am trying to figure out how to dial out using an Asterisk server to our pa system ext 600. I am using source forge astconman for VB.net I have spent days trying to figure out how to make it work. I am totaly lost I set the config file as such

<?xml version="1.0" encoding="utf-8" ?>
<config
  DSN="DSN=testodbc"
  debug="false">
    <server name="Asterisk"
            hostname="plastikon.com"
            port="5060"
            username="221"
            secret="pass1234"
            httptimeout="60"
            sysstatshistory="100"
            eventhistory="1000">
      <serverscheduledactions>
      </serverscheduledactions>
    </server>
  <scheduledactions>
    <scheduledaction interval="60000" immediate="True" id="sippeers">
      <sippeersaction />
    </scheduledaction>
  </scheduledactions>
</config>

The IT department gave me the proper login info not sure about the server name if it is critical or not. They tell me that this is not even getting to the server according to the log files. I have included the astconman vip file if needed. Any help would be greatly appreciated.
