[Asterisk-java-users] OriginateAction.setVariable

[Tobias W. <tob...@ev...>]

Hi,

first of all i am still using asterisk-java-0.1 because i didn't want to 
disturb the AGIs presently in use :-S

I wanted to set a Variable while i am originating a call. Here is what i 
wrote:

OriginateAction originateAction = new OriginateAction();
originateAction.setChannel("Local/5000@test");
originateAction.setVariable("var1=TEST");
originateAction.setApplication("MeetMe");
originateAction.setData(number);
originateAction.setTimeout(new Integer(30000));

ManagerResponse originateResponse = 
managerConnection.sendAction(originateAction, 30000);

Here is the extension:

exten => 5000,1,Answer()
exten => 5000,2,NoOp(Our var should be printed here : ${var1})
exten => 5000,3,Playback(demo-abouttotry)
exten => 5000,4,Hangup()

The call is executed correctly and the sound is streamed into the 
conference, but the channel variable is not.

I also have tried out an call file:

Channel: Local/5000@test
SetVar: var1=100
Application: MeetMe
Data: 333

With the same result.

Can anybody point me to my fault ??

Greetings,

tobias

You can still use your "old" AGIs with Asterisk-Java 0.2-rc1 though you
will get a compile time warning about using a deprecated API.

When originating a call two channels are involved. Let's asume you
originate a call from A to B then what happens looks like:

A channel is created to A:
----> A
A is ringing
When A is answered the second channel is created:
----> A ----> B
The channel variables are set on the channel from A to B only.

So when you change your example to

        OriginateAction originateAction =3D new OriginateAction();
        originateAction.setChannel("Local/5000@test");
        originateAction.setVariable("var1=3DTEST");
        originateAction.setExten("5001");
        originateAction.setContext("test");
        originateAction.setPriority(new Integer(1));
        originateAction.setTimeout(new Integer(30000));

and your extensions.conf to

[test]
exten =3D> 5000,1,Answer()
exten =3D> 5000,2,NoOp(Our var is not printed here: ${var1})
exten =3D> 5000,3,Playback(demo-abouttotry)
exten =3D> 5000,4,Hangup()

exten =3D> 5001,1,NoOp(Our var is printed here: ${var1})
exten =3D> 5001,2,MeetMe(1)

you will see that your channel variable is actually set on the channel
to the MeetMe room.
Does that help in your case?

thx for you explanation, it helps to improve my overall understanding of 
the concept, although i am not really happy with it, but this is 
something a have to live with, i guess :)

the main idea of what i want to do is the following:
stream an audio file (which is variable) into a conf room (which is also 
variable, of course). the problem is that i have to set something in 'A' 
and in 'B'.

Since variables only appear in the called channel (B) it is only useful 
to send the conf room number per variable and the problem stucks with 
the file to stream, which has to be set in A.

so i switched to use
	originateAction.setChannel("Local/"+number+"@confannounce"); 

         originateAction.setApplication("Playback");
         originateAction.setData(file);

	[confannounce]
	exten => _X.,1,NoOp(This is the conf room number in which to stream: 
${EXTEN})
	exten => _X.,2,MeetMe(${EXTEN})
	exten => _X.,3,Hangup

This approach connects to the Local Channel. I tried even to set 
variables in this szenario, but they does not apppear accordingly to the 
valuable information of Stefan. After the Channel is answered, wich is 
done by the MeetMe-Application, the Application is executed which is 
defined in the Originating-Action.

so, in the end i think i have reached the behavior i wanted.

thx for the help :)

ok.
For more complex scenarios i like to join AGIs into a MeetMe conference.
You basically use the OriginateAction to create a channel that executes a
FastAGI and pass some kind of id via the AGI URL. Then its up to your
application to provide a script for the AGI and look up what to do based
on the id.
