[Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Jorge <gus...@gm...>]

Hi:

I have the next scenario. I am triying to call from pstn to a conference in
Asterisk server. I have set up the dial plan so the main telephone number
is the the conference so calling for example 555-555555 you get into the
conference.

My objective is capturing this channel from java to send tones from
Asterisk to the phone. What I am triying to do is the next thing :

    managerEventListener = new ManagerEventListener(){
            public void onManagerEvent(ManagerEvent event) {
             if(event instanceof MeetMeJoinEvent ){
                    MeetMeJoinEvent meetMeJoinEvent = (MeetMeJoinEvent)
event;
                    String server = meetMeJoinEvent.getServer();
                    meetMeJoinEvent.getCallerIdNum();
                    System.out.println(meetMeJoinEvent.getChannel());

                    try{
                        AsteriskChannel asteriskChannel =
asteriskServer.getChannelByName(meetMeJoinEvent.getChannel());
                        System.out.println(asteriskChannel);
                        //asteriskChannel.playDtmf("1");
                        System.out.println("terminado");
                    }catch(ManagerCommunicationException e){
                        logger.error("Error al obtener el canal " + e);
                        System.out.println("Error " + e);
                    }
                }
            }
        };

That is to say I am capturing the MeetMeJoinEvent to see when this phone
has been connected to the conference. With this event I am able to get the
channel name and with the instruction the channel structure but I get :
"org.asteriskjava.live.ManagerCommunicationException: Timeout waiting for
events from StatusAction"

The great thing is that when I originate the call from Asterisk with
"asteriskChannel = asteriskServer.originateToExtension("DAHDI/g0/" +
numero, contexto , conferenciaNumeroSip, 1, 10000);" it is able to get the
channel.

Could you let me know what I am doing wrong?

Thank you very much for your help.

Hi,

Just to make sure I understand you right...:

1.)  Phone x calls into your conference via pstn
2.)  you want to "hijack" the channel or superimpose DTMF ?

If you use asterisk 11.x you could do some specials like this, but to 
call via java into the conference and send the tones would be easier... or
is it a constraint, that other users in the conference must not hear the 
tones?

regards,
yves

Re: [Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Jorge <gus...@gm...>]

Hi :

Thank you very much for your answer. What I would like to do is to send and
receive dtmf tones when Asterisk call to a telephone o receive a call from
a telephone. The problem I had I don´t know how to manage the call
connection so I decided to call to a conference. On this way the call is
not hung up while I am sending the tones.

The idea is the other won´t listen the tones so I can manage n connections
using only one conference room.

I think 2) really dosen´t matter because no other data will flow throught
this call only DTMF tones. I am not sure if I understood this point
properly.

You said "call via java into the conference and send the tones would be
easier."  I think this is right but I need to handle incoming calls, this
why I need the channel.

Do you need more information?

Thank you for your answer.



Jorge

Re: [Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Yves A. <yv...@gm...>]

hi,

well... now I am more confused than before... would be helpful to read 
your scenario and objective from the beginning...
Dont save words, the more you explain, the better...
What is the purpose of sending DTMF into a conversation?
Incoming calls can be handled either by hooking on events or routing the 
call to a (java-)agi.
But again, as long as I do not exactly understand your objective / 
problem / scenario these are only common tips...

Re: [Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Jorge <gus...@gm...>]

Hi,
Sorry :( . Let´s start again, I will try to clarify a bit the scenario. I
am really new to Asterisk I will try to do my best.

I want to talk to a device using DTMF tones using Asterisk. The main
problem is that the device can call o receive a call to/from Asterisk. The
main problem is that if the device is not connected to an extension (SIP
extension) or to a conference, the device hang up the call so it is
finished.

My idea taken from here (
http://blogtech.cardosi.net/2014/01/15/tutorial-on-lamj-part-4/) is
connecting the device to a conference. And sending the DTMF tones using the
channel that has been created.  Is it right? Do you have a better solution?

First case, If Asterisk calls I use (from
http://blogtech.cardosi.net/2014/01/15/tutorial-on-lamj-part-4) :

AsteriskChannel asteriskChannel =
asteriskServer.originateToExtension(channelName, "default",   "8600",
1, 10000);
asteriskChannel.playDtmf("1");

And a listener that detects the DTMF event that arrives. Like this (more or
less, it is not the exact code I am using) :
        ManagerConnectionFactory factory = new ManagerConnectionFactory(
                ip, user, password);
        managerConnection = factory.createManagerConnection();
        // login to Asterisk
        managerConnection.login();
        // Instantiate a new AsteriskServer
        asteriskServer = new AsteriskServerImpl(managerConnection);
        managerConnection.addEventListener(new ManagerEventListener(){
            public void onManagerEvent(ManagerEvent event) {
                if (event instanceof DtmfEvent) { ...

Second case and here is  the problem. What I have done is setting up the
incoming calls to the conference. So when the device calls the input is
directed to the conference and starts sending DTMF tones. With the DTMF
tone I get the channel name (DtmfEvent.getChannel())  but when I try to get
the channel object from the channel name
(asteriskServer.getChannelByName(mensaje.getCanal());) is where I have the
error.

"org.asteriskjava.live.ManagerCommunicationException: Timeout waiting for
events from StatusAction"

Please, let me know what is not explained and done properly.

Kind regards and thank you for your help.

Re: [Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Yves A. <yv...@gm...>]

Hi,

so... if this is not a human call and all you need is call to or receive 
a call from such a device and kind of control it via dtmf, then I would 
recommend to use an (java-) agi-script.
For an incoming call you route the call to your script and the device is 
connected to the channel you control with your agi... as long as your 
script or the device hangs up.
For an outgoing call just initiate a call between your extension that 
routes to the agi-script and the extension / number you have to dial to 
reach your device.
within the agi you have access to the channel and can directly send or 
receive dtmf-tones.
if you want to use java agi scripts, take a look at the docs for 
asterisk-java. there is a tutorial. java-agi is really great... see it 
as some kind of a java-dialplan.
the only annoying thing is that you have to reload the agi-server each 
time you modify your agi-classes, as they are cached... I wrote a 
wrapper that allows me to write
java-agi in a text-file that are executed in realtime... so i dont have 
to compile and deploy them anytime... just change the script and without 
reloading the server the
changes immediately become applied in the next run...
