In your case you are doing outbound event socket. The dialplan calls the socket app which does an outbound socket
connection to port 9090 on the localhost. Make sure that your app is listening on port 9090.<br>
<br>The event_socket.conf.xml file is for configuring inbound socket connections, e.g. when you have a script that attempts to connect to FS where FS is listening on port 8021. So change your event_socket.conf.xml file back to the default and retry. <br>
<br>Report back here if you have trouble. Also, buy or borrow the FreeSWITCH book and check out chapter 9. Lots of good stuff there on how the even system works.<br><br>-MC<br><br><div class="yiv2025939577yiv878749678gmail_quote">On Thu, Oct 28, 2010 at 2:14 PM, Will Smith <span dir="ltr"><<a rel="nofollow">willbelair@yahoo.com</a>></span> wrote:<br>
