Did you properly build the php ESL module?<br><a href="http://wiki.freeswitch.org/wiki/Esl#Installation">http://wiki.freeswitch.org/wiki/Esl#Installation</a><br>In libs/esl you need to "make" and "make phpmod-install"<br>
<br>Note: If your php script is running on a system that does not have FreeSWITCH then you will need to download and build ESL on the machine where the script is running, or you need to move the necessary *.so files over to that target machine.<br>
<br>Also, I see that you mention that you are running this in a browser. I'm not sure that is what you need to be doing. I'll defer to more experienced Web programmers. However this much I can tell you: if your php script isn't actively running and waiting for a socket connection on port 9090 then this whole thing will fail completely. Using the socket app from the dialplan implies that the program on the other end will be sitting around waiting for a phone call to come in while listening on the port in question and will actively control the call. The test script you pasted here is the exact opposite of that: it is a script that connects *to* FreeSWITCH, not one that sits around waiting for a connection *from* FreeSWITCH.<br>
<br>I think you may need to break down your project into some smaller pieces. The first thing is to do is define the scope of your project: what all does it need to do? Does it need to answer a call and control it? If so you need a daemon of some sort that sits around waiting for calls from FS. Do you need to update a Web page? If so then you'll need to have some way for the Web server to communicate either with FreeSWITCH directly or with your daemon, or with a 3rd party data source, or whatever. <br>
<br>You might want to join #freeswitch at <a href="http://irc.freenode.net">irc.freenode.net</a> so that you can connect with other FS users and developers. You also should consider #fusionpbx and #2600hz because both of those channels are frequented by programmers who are familiar with PHP Web development and FreeSWITCH. <br>
<br>Hope this helps.<br>-MC<br><br><div class="gmail_quote">On Fri, Oct 29, 2010 at 1:01 PM, Will Smith <span dir="ltr"><<a href="mailto:willbelair@yahoo.com">willbelair@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<div></div><div class="h5"><br><br><div>Be sure to learn the difference between inbound and outbound event socket. 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.
