Interestingly, even though JavaScript is the most developed of the control languages, there is a dearth of sample scripts in SVN. Try here for help:

http://wiki.freeswitch.org/wiki/Category:Javascript

I don’t see any examples that explicitly use new.Session() so possibly you could try mimicking the examples available and see if there’s a quirk in how your script is attempting to work…

You have an error in your script, so the call is aborting.

I need some help using the ignore_early_media.

I am using a javascript file to dial a number from a asterisk server and play a file to the person who answers the phone.

The problem I am having is relatated to the early_media. I think I am doing something wrong. But I cannot discover what it is.

here is my .js file:

----------------------------------------------------------------------------------------------------------------------------------------------------

var languageCode = "en";
var soundDir = "sounds/";
function playFile(fileName, callBack, callBackArgs)
{
new_session.streamFile(soundDir + languageCode + "/" + fileName, callBack, callBackArgs);
}
new_session = new Session();
new_session.setCallerData("caller_id_name", "6130356060");
new_session.originate(session, "{ignore_early_media=true}sofia/gateway/asterisk/9133803764");
new_session.waitForAnswer();
if(new_session.ready()){
playFile("HelloWorld.wav");
}
exit();

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Here is the Freeswitch output:

The problem is:

If in the originate command I use the {ignore_early_media=true} option. The script to play the file is executed when the call is answered. But the person who answers the phone cannot hear the .wav file.

If I do not use the {ignore_early_media=true} option. The script to play the file starts when the call is preAnswered. And when the person in the phone answer the call, can hear the sound of the .wav file, but the audio has already started (when the preanswer is executed).

ps: the computer that is making the call is a asterisk server, connected with the FS by sip, and the call is made by zaptel whe pri isdn signalling.

I would like to know if I am doing something wrong or this is a bug in the system.

Thanks for the help.
