[Freeswitch-users] http://wiki.freeswitch.org/wiki/Java_ESL_Client, how I can make a connection before starting to handle Outbound connection ?

Hi,

Please take a look.

I'm using node.js and esl (https://github.com/shimaore/esl) 
Programming ESL Client and Server using node.js (http://nodejs.org/), it's
also cross-platform. 

For example, 
-------------------------------------------------- 
// 
// esl-test1.js 
// 

var esl = require('esl'); 
var util = require('util'); 

var audio_file = []; 
// 
// play and get digits 
// <min> <max> <tries> <timeout> <terminators> <file> <invalid_file>
<var_name> <regexp> <digit_timeout>
// 
audio_file[0]='1 1 3 5000 # sounds/mywav/0.wav'; 
audio_file[1]='1 1 3 5000 # sounds/mywav/1.wav'; 
audio_file[2]='1 1 3 5000 # sounds/mywav/2.wav'; 
audio_file[3]='1 1 3 5000 # sounds/mywav/3.wav'; 
audio_file[4]='1 1 3 5000 # sounds/mywav/4.wav'; 
audio_file[5]='1 1 3 5000 # sounds/mywav/5.wav'; 
audio_file[6]='1 1 3 5000 # sounds/mywav/6.wav'; 
audio_file[7]='1 1 3 5000 # sounds/mywav/7.wav'; 
audio_file[8]='1 1 3 5000 # sounds/mywav/8.wav'; 
audio_file[9]='1 1 3 5000 # sounds/mywav/9.wav'; 
audio_file[10]='1 1 3 5000 # sounds/mywav/10.wav'; 
audio_file[11]='1 1 3 5000 # sounds/mywav/11.wav'; 
audio_file[12]='1 1 3 5000 # sounds/mywav/12.wav'; 
audio_file[13]='1 1 3 5000 # sounds/mywav/13.wav'; 

var error3 = '1 1 3 5000 # sounds/mywav/error3.wav'; 
var welcome = '1 1 3 5000 # sounds/mywav/hello.wav'; 


var server = esl.createCallServer(); 
//var server = esl.createClient(); 

server.on('CONNECT', function(req, res) { 

        var uri, channel_data, unique_id; 

        channel_data = req.body; 
        unique_id = channel_data['Unique-ID']; 
        

        req.execute('answer'); 

        //req.execute('playback', 'sounds/mywav/hello.wav'); 
        
        //req.execute('play_and_get_digits', '2 5 3 7000 #
sounds/mywav/hello.wav sounds/mywav/error3.wav myFoo \d+'); 
        req.execute('play_and_get_digits', welcome); 

        req.on('DTMF', function(req) { 
                
                //util.log('DTMF:'+util.inspect(req, null, null)); 
                
                var digit; 
                var channel_data; 
                channel_data = req.body; 
                unique_id = channel_data['Unique-ID']; 

                util.log('DTMF: unique_id='+unique_id); 

                digit = channel_data['DTMF-Digit']; 
                console.log('DTMF Received=' + digit); 
                util.log('DTMF Received'); 
                if(digit==='#' || digit==='*'){ 
                        
                        req.execute('play_and_get_digits', error3); 
                        
                        
                } else { 

                        var n = parseInt(digit); 
                        
                        req.execute('play_and_get_digits', audio_file[n]); 

                        
                } 
                
                
                return; 
        }); 

        req.on('CHANNEL_ANSWER', function(req) {

        });

                //util.log('CHANNEL_HANGUP:'+util.inspect(req, null, null)); 
                var channel_data;

        }); 
        
        req.on('CHANNEL_HANGUP_COMPLETE', function(req) { 
                
                ///util.log('CHANNEL_HANGUP_COMPLETE:'+util.inspect(req,
