Re: [Asterisk-java-users] PRI Hangup Cause

[Chetan M. <che...@pi...>]

Hi Yves ,

 Thanks for your response. 
 Here the pseudo code of my
application and dialplan. Paste-bin link
http://pastebin.com/tAqEb5FF

JAVA-CODE:

import java.util.HashMap;
import
java.util.Map;
import
org.asteriskjava.manager.AbstractManagerEventListener;
import
org.asteriskjava.manager.ManagerConnection;
import
org.asteriskjava.manager.ManagerConnectionFactory;
import
org.asteriskjava.manager.action.OriginateAction;
import
org.asteriskjava.manager.event.CdrEvent;
import
org.asteriskjava.manager.event.HangupEvent;
import
org.asteriskjava.manager.event.OriginateResponseEvent;

public class
ContactDialer {

 private ManagerConnection pbx;
 private String context
="broadcast";
 private int priority=1;
 private String extension="555";

private String channel= "zap/g1/";

 public void connectToPBX(String
host,String user,
 String secret,int port) throws Exception{

 /*Create
connection to Asterisk
 server and Register Event Listener*/

 pbx= new
ManagerConnectionFactory(host, port, user, secret).

createManagerConnection();

 pbx.login();

 pbx.addEventListener(new
DialerEventListener());

 }

 public void dial(String number,String
mssgFile,String actionID)throws Exception{

 /*calls a number using any of
channel in group g1
 and transfer the call to extention 555 in dialplan*/


OriginateAction oAction= new OriginateAction();

 oAction.setAsync(true);

oAction.setChannel(channel +number);
 oAction.setContext(context);

oAction.setPriority(priority);
 oAction.setActionId(actionID); //Actionid
to identify a call

 oAction.setVariable("mssg", mssgFile); /*this variable
will
 be used in dialplan to play the voice-message*/

pbx.sendAction(oAction);
 }

 public static void main(String[] args) throws
Exception{

 /*The number and message file name are
 retrieved from
database*/

 String number ="XXXXXXX"; //Number To be called
 String
messageFile="message"; //File to be played

 ContactDialer cd=new
ContactDialer();

 cd.connectToPBX("localhost", "user", "secret",5038);


cd.dial(number, messageFile, "action-id"); /*actionid to uniquely identify
a call,
 generally a database key value*/

 Thread.sleep(1000*60*2);
//since it is pseudo code call a number and wait for response*/


}
}

class DialerEventListener extends AbstractManagerEventListener{


private Map callResponse= new HashMap();
 @Override
 public void
handleEvent(OriginateResponseEvent event){

 /* get action id and associate
it with
 uniqueid for further use*/

 if(event.isSuccess()){


callResponse.put(event.getUniqueId(), event.getActionId());
 }
 else{

//call failed, log its details to database

 }

 }

 @Override
 public void
handleEvent(CdrEvent event){
 /*get Actionid and log it to database*/


if(callResponse.containsKey(event.getUniqueId())){
 /*we have a successful
call */
 }
 }

 @Override
 public void handleEvent(HangupEvent event){


/*
 this is problem area, how to associate hang-up cause with a call ?

 No
uniqueID is generated in OriginateResponse for failed call.
 */

if(event.getCause() == 16){
 /* call succeeded - log it to DB when we get
the CDR*/
 }

 }
}

DIALPLAN (dialplan really simple ;)
)

[broadcast]
exten => 555,1,Answer()
exten =>
555,n,Playback(${mssgFile})
exten => 555,n,waitExten(4)
exten =>
555,n,Hangup()
