I got FreeSwitch running today and connected a softphone to it. Yippee!

But ran into some snags trying out Javascript within a dialplan.

My FreeSwitch is running on Windows XP and from the same machine I use an X-Lite softphone to call and play around while learning how Javascript and FreeSwitch work together.

The first snag was the location of the default dialplan file given in the "Quickstart" (http://wiki.freeswitch.org/wiki/Javascript_QuickStart). It is "conf\dialplan\default.xml" on my system and not as the "Quickstart says in "conf/default_context" since "default_context" does not exist.

Next, trying the JavaScript Quickstart HelloWorld.js example, I get the following errors which indicate a different location is needed for the .wav file from what the "Quickstart" says and this also requires two more new folders (sound & en) nested inside folder callie. Now, either I did something wrong or the instructions need more updating.

I suppose I could have not used variables "languageCode" and "soundDir" but I decided to create the two new folders and placed the .wav file in folder "en" (C:\Program Files\FreeSWITCH/sounds/en/us/callie\sound/en/HelloWorld.wav).

Also, I removed the arguments 'callBack' and 'callBackArgs' from 'session.streamFile(soundDir + languageCode + "/" + fileName, callBack, callBackArgs);'.
Otherwise, I would get the following error:

2008-10-27 22:58:08 [ERR] HelloWorld.js:6 mod_spidermonkey() TypeError: callBack is not a function

This gives me an updated HelloWorld.js file that looks like this:

var languageCode = "en";
var soundDir = "sound/";

function playFile(fileName, callBack, callBackArgs)
{
session.streamFile(soundDir + languageCode + "/" + fileName);
}

session.answer();
playFile("HelloWorld.wav");
exit();

The command line interface gave the following and I finally heard my HelloWorld.wav file

However, the sound has was quite static filled.
What's the cause of all that static and how do I fix (remove) it?
