Originate call to sip trunk via asterisk manager api java

So I am a total newbie in asterisk and managing call lines in general but I managed to install Asterisk Now 13 distro, I have connected 2 sip phones with pjsip and configured a sip trunk which works when I dial an external number with the corresponding prefix. Now I have to programmaticly originate calls and connect them to local extensions which I have no idea how to achieve and I cant seem to find much information about it on the internet after hours of searching.
I managed to connect 2 local sip phones with the asterisk manager api and OriginateAction in the following way:
originateAction = new OriginateAction();
originateAction.setChannel(ConnectionType+"/"+extCaller);
originateAction.setContext(context);
originateAction.setCallerId(idCaller);
originateAction.setExten(tDestination);
originateAction.setPriority(priority);
originateAction.setTimeout(timeoutCall);
managerConnection.login();
originateResponse = managerConnection.sendAction(originateAction, timeoutRequest);
I also tried this channel originate pjsip/201 extension number#from-ptsn and channel originate local/201#from-local extension number#trunkName .
The context of the PJSIP trunk is from-pstn,I tried using that in various ways without luck both in asterisk cli and the application.
How do I make it use the PJSIP trunk when originating the call and make a call out of the office?
EDIT: I originated an outgoing call using a number that completes with the trunk outgoing route requisites and the "from-internal" context like this:
channel originate Local/201#from-internal extension (prefix)numberToCall#from-internal
I still do not understand why this works and if it is the correct answer to my question.

So the answer is in the edit of the question. The only way to generate an outgoing call that I could find is to originate that call "internaly" (with the context "from-internal" which happens to be the same context that is used when originating internal calls) introducing a target number value that completes with the sip trunk's route pattern requirements.
Example:
I have a route configured for the sip trunk( trunk1 ) with a pattern(RegEx): [0]{1}/number/ that means that with a 0 infront of any nubmer it will be a valid value for that route and it will try to call using trunk1.
In the case of AsteriskNow CentOS installation it happens to be with the context "from-internal". Since the asterisk configuration files are owned by the FreePBX it is recomended to use the FreePBX GUI instead of configuring the .conf files of asterisk manualy.
That concludes to :
channel originate Local/201#from-internal extension (0)[numberToCall]#from-internal
Which will make the extension 201 ring first and when picked up it will try to use the sip trunk to dial that [numberToCall] because the route with the 0 is "called".
In order to send that command to asterisk using asterisk-java I wrote the following code:
ManagerConnectionFactory factory = new
ManagerConnectionFactory("serverIp", "username",
"passwd");
ManagerConnection managerConnection=factory.createManagerConnection()
OriginateAction originateAction=new OriginateAction();
final String randomUUID=java.util.UUID.randomUUID().toString();
System.out.println("ID random:_"+randomUUID);
originateAction.setChannel([connectionType]+"/"+[callerExtension]);<-- SIP or PJSIP / 201(the phone that will ring first)
originateAction.setContext("from-internal"); <-- Default FreePBX context
originateAction.setCallerId([callerId]); // what will be showed on the phone screen (in most cases your phone)
originateAction.setExten([targetExten]); //where to call.. the target extension... internal extension or the outgoing number.. the 0[nomberToCall]
originateAction.setPriority([priority]);// priority of the call
originateAction.setTimeout(timeoutCall); // the time that a pickup event will be waited for
originateAction.setVariable("UUID", randomUUID); // asigning a unique ID in order to be able to hangup the call.

Java desktop bluetooth client can not find services

I am new to bluetooth programming, so please keep that in mind.
I am trying to connect to a pulse sensor from a desktop pc, specifically the Zephyr HxM BT. I am not using any device specific drivers, the Java bluetooth library I'm using is Bluecove, and my bluetooth stack is BlueSoleil.
From my understanding, the way I proceed is
1) Scan for BT devices
public void startSearch() throws BluetoothStateException{
System.out.println("Inquiry started");
localdevice.getDiscoveryAgent().startInquiry(DiscoveryAgent.GIAC, this);
}
This works fine, it discovers my pulse belt and calls
public void deviceDiscovered(RemoteDevice arg0, DeviceClass arg1)
2) Search a device for services
Once a device has been discovered, it should be added to the DiscoveryAgent's list of cached devices, this is my first problem as the cache (and preknown devices) is always empty even though I've discovered my belt.
So the way that I do this now is to either keep my own list of devices, or simply start a service search directly from deviceDiscovered.
I am still a bit unsure if I'm using the correct parameters, but from reading the BT device manual and the javax.bluetooth documentation on DiscoveryAgent.searchServices:
public int searchServices(int[] attrSet,
UUID[] uuidSet,
RemoteDevice btDev,
DiscoveryListener discListener)
throws BluetoothStateException
My code:
public void searchServices(RemoteDevice device){
UUID[] uuidSet = new UUID[1];
uuidSet[0]=new UUID("1101",false); //Serial Port
System.out.println("Searching for services on " + device.getBluetoothAddress() );
try{
agent.searchServices(null,uuidSet, device,this);}
catch (BluetoothStateException e){
System.out.println("BluetoothStateException caught.");
}
}
I've set the attributes parameter to null, because the documentation states that this will have it search for services with the default attributes, however I've also tried to use only ServiceID (0x0003) as attribute with no luck.
This is where I'm stuck, I pass the correct BT device into the function, and it starts searching but never give me any results, it just searches forever for all I know, no exception, no calls to
public void servicesDiscovered(int arg0, ServiceRecord[] arg1)
or
public void serviceSearchCompleted(int arg0, int arg1)
So I guess my questions are:
- Am I doing something wrong? Any suggestions?
- What are the other approaches to connecting to a BT device, and what
information do I have to know about the device to do that?
Here is some information that I think is relevant from the device manual:
The following steps have to be undertaken to connect to a HxM device.
1) Activate the Bluetooth service of the device/computer wanting to connect to the HxM
2) Scan for Bluetooth devices in range
3) Pair with the HxM device found in range
4) Discover Services of Paired HxM
5) Connect to serial port of HxM device
The diagram above shows that the Bluetooth HxM typically communicates with a mobile device over the Bluetooth
link. The HxM only supports one link at a time and uses the Bluetooth SPP (Serial Port Profile) to communicate
with other devices with the following low-level protocol:
• 115,200 baud
• 8 data bits
• 1 stop bit
• No parity
Any suggestions are very much appreciated
edit: I just want to add that I'm testing the code with a console input loop, so the program is not immediately terminated after calling searchServices, it should have time to complete unless I'm misunderstanding async tasks

I just wanted to update this and say that I found the problem, it seems that I had to use a short UUID instead of a long. I should have tried both of these options before I deemed myself stuck, but I didn't think it would make any difference.

Please anybody tell me how to fix this issue

basically you the program is unable to find the PORT,use
org.smslib.helper.CommPortIdentifier
to find the correct COM port from the list of ports.

I know this is not the sort of answer you expect on SO but given the alternative I think it's better than nothing.
a) Your library is reporting that your modem is not attached.
b) You don't know how to check if your modem is attached.
While not in any way related with the company I've used nexmo with great success in the past.
If it's a necessity of your app I would strongly suggest you approach the problem by the API route that will save you enormous amount of work.
There are several companies out there that provide this service and the usage is more or less straight-forward, you simply format a URL to pass parameters back to the company. Nexmo example:
// by calling a crafted url you are requesting the company to send the sms for you
urlString = "https://rest.nexmo.com/sms/json?api_key={api_key}&api_secret={api_secret}&from=MyCompany20&to=447525856424&text=helloworld";
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream()
Nexmo is NOT the only one out there providing this service. They are the only one i've had hands on experience with.

Copy the API(comm.jar),dll(win32com),properties file(javax.comm) in
1) If Net Beans tool you are using means
C:\Program Files\Java\jdk1.7.0\jre\lib\ext
and
C:\Program Files\Java\jdk1.7.0\jre\bin
2) If Eclipse tool you are using means
C:\Program Files\Java\jre7\lib\ext
and
C:\Program Files\Java\jre7\bin
as per the instructions given in Code projects.com where you downloaded this project.
Another way If you can configure your tool then do it, logic is the API's should be under your runtime JVM(jre).
and make sure that the port which is given by you should be free that is no other apps should run on it.

Yes I also got this exception to in Harshadura's SMS wrapper.Their can be two things you did not do
You did not declare any appenders in the code so at the beginning of
your code just type in this simple code to declare appenders.

Identifying the port of your GSM modem. This you can solve by going to your My Computer Icon click manage > click device manager> click modems and Identify the port of your modem.
The port you identifed then write it on your code.String port="MyPort";

Java RMI connection to localhost at home network can't find correct remote module

I have been working on this project where two modules on different machines need to be in communication through RMI.
I start both client and server modules on my laptop. RMI seems to work correctly when i am at work and connected to work network, but when i am home, connected to my home network it does not work. It says remote object could not be found.
Here is the method i use at CLIENT side to get the reference to remote object
public static MyRMIApp getRemoteApp() throws RemoteException, NotBoundException, AccessException {
Registry registry = LocateRegistry.getRegistry("localhost", 28999); // tried 127.0.0.1 instead of localhost here, still not working
MyRMIApp app = (MyRMIApp) registry.lookup("COM");
return app;
}
Digging up a bit with some debugging, when i check the object value returned from getRemoteApp method, it shows me the end point is 67.215.65.132. Which is openDNS i am using to connect to internet. Shouldn't that be 127.0.0.1 ?
Then i used my mobile internet and tried again. It seems to be working but end-point is not 127.0.0.1 again it is the address assigned to me, which is 192.168.x.x
So can anybody please tell me what is wrong i am doing here ? I really would appreciate the help.
Oh and this is the piece of code at SERVER side
//Somwhere up top
private final static MyRMIApp rmiApp = new RMIServer();
//Down below
MyRMIApp stub = (MyRMIApp) UnicastRemoteObject.exportObject(rmiApp, 0);
Registry registry = LocateRegistry.createRegistry(28999);
registry.rebind("COM", stub);

See item A.1 of the RMI FAQ: specifically, 'The appropriate workaround is to set the system property java.rmi.server.hostname when starting the server.'

Sending messages from pc via mobile phone using java

I am working on an application, using java, that has the following features:
User connects his mobile to a PC using a usb cable or bluetooth.
User types a message on his PC (in the textfield provided by my software).
User types a phone number (in a textbox provided by my software).
User clicks the send button.
Then, the software should send the message to the specified phone number and appropriate charges should be applied to my mobile balance. In other words, I am directing my mobile through my software to send message to a specified number.
How shall i do that? Is core java sufficient for this purpose or i have to use j2me or is there any particular java framework that would be suitable for this?

One option is to connect the phone to the pc using serial link (COM). Need to configure the phone connected physically by USB or Bluetooth in order to appear in a COM (serial) port.
Then you need to create an application for PC (Java or whatever can open serial ports) that opens the COM port used by the phone and send the proper AT commands. Serial port can be opened by JavaComm 2.0 Win32 or more recently RxTx.
Open the serial port and write and read command by writing and reading bytes, in the same way a socket.
Then create a visual application that let user set the information like phone number for destination, text...
You need Java SE or whatever language allows you to create visual applications and opening serial ports (Java, .NET, Python...).
Some links about AT commands by serial port in Windows: 1, 2, 3.
Another option could be using native API from the mobile OS through a socket, but seems complex and using AT commands and serial port should work for all phones and the only problem is connecting the phone by serial over USB or BlueTooth and managing the serial port.

This is highly dependent on the Mobile OS you're using. Are you using Windows Mobile, Android OS, BlackBerry OS?
If you're using Android, then you should use the built in SmsManager to do that. The SmsManager can do the following:
Manages SMS operations such as sending data, text, and pdu SMS messages.
Update:
Since you're using Symbian OS, then check out the documentation for more information on sending SMS messages. I assume that you can figure out the rest (i.e. how to get the text fields for the number and the message, etc.)
Here is an example from the Symbian OS documentation:
public boolean sendSms(String number, String message){
boolean result = true;
try {
//sets address to send message
String addr = "sms://"+number;
// opens connection
MessageConnection conn = (MessageConnection) Connector.open(addr);
// prepares text message
TextMessage msg =
(TextMessage)conn.newMessage(MessageConnection.TEXT_MESSAGE);
//set text
msg.setPayloadText(message);
// send message
conn.send(msg);
conn.close();
} catch (SecurityException se) {
// probably the user has not allowed to send sms
// you may want to handle this differently
result = false;
} catch (Exception e) {
result = false;
}
return result;
}
The above snippet came from the guide on "How to Send Text SMS in Java ME"
