Originate call to sip trunk via asterisk manager api java

Question

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.
