[Asterisk-java-users] Interrupting StreamFile with DTMF digits.

[John M. <jo...@sy...>]

Hi,

I have an application where I need to interrupt the StreamFile command with
a DTMF "*" - I cannot seem to get it to work and I just wanted to check that
it does work in the following configuration.

I am using asterisk-java-0.1 and Asterisk 1.0.9 and the following is the
line of Java.

        streamFile(i_channel, "prompt/a.wav","*");

The file just plays like as if it was a Playback command as opposed to a
Background command.

best regards,
John.

Have you verified that you are receiving DTMF tones.  I ran into a
similar problem and discovered that my Asterisk/VoIP configuration was
not detecting the tones.  My situation turned out to be the firewall
blocking and a wrong SIP configuration.

RE: [Asterisk-java-users] Interrupting StreamFile with DTMF digits.

[John M. <jo...@sy...>]

Yes, Jonathan, I am receiving DTMF happily in the rest of the application.
However, all the rest of the DTMF input takes place in extension.conf. It
appears to be only when the application is in the FastAGI script that it
does not recognise the DTMF tones.

Is there anything that has to be enabled to pass DTMF digits to AGI?

no it usually "just works" :)

I would suggest you to use the latest release of Asterisk-Java (i.e.
0.2) and try to reproduce the problem with that version. And you could
try to allow other dtmf digits to be pressed like streamFile("myprompt",
"1234");

[Asterisk-java-users] How to Answer the phone and call an application.

[Brett S. <bs...@no...>]

I'm trying to write an application that can monitor specific channels 
and when a call comes in answer the call and call an application (rx_fax).

I think I've worked out how to detect that a channel is ringing but I'm 
don' now how to answer it and call an application.
I've looked at the OriginateEvent but that seems to be for makeing 
outbound calls.

Any help would be appreciated.

Regards,
Bret.

Re: [Asterisk-java-users] How to Answer the phone and call an application.

[Stefan R. <sr...@re...>]

Have a look at RedirectAction it allows you to redirect a channel to an
extension. That extension should then call the application.
The other option is to not use the ManagerAPI at all for this stuff but
implement an AGI script and map the fax extensions to that AGI script.

RE: [Asterisk-java-users] Interrupting StreamFile with DTMF digits.

[John M. <jo...@sy...>]

Hi Stefan,

I have upgraded to 0.2 on Asterisk 1.0.9 and I have the same problems. I
also tried other escape characters such as 1, 2, etc.

Using the AGI debugging I notice the AGI command used has the following
syntax.
>>> STREAM FILE "myprompt" "1"

where the digit "1" is the valid escape digit.

I found the following example in the AGI Help ...

STREAM FILE welcome #
Plays the file 'welcome'. If the user presses the '#' key the playing stops
and the command returns 200 result=35

Note
Don't give an extension with the filename.
Asterisk looks for the file to play in /var/lib/asterisk/sounds
Use double quotes if the message should play completely. For example to play
audio file 'welcome' without allowing interruption by digits use: STREAM
FILE welcome ""


The last comment might suggest that the quotes around the escape digits
might lead the interpreter to play the file fully as the previous example
does not have any quotes on the escape digit.

Does anyone have an example of a working AGI STREAM FILE command with escape
digits provided.

thanks for any help,
regards,
John.

nope escaping just works fine.
I suggest you to have a look if your general DTMF setup is ok as this
problem does not seem to directly relate to the AGI stuff.

I tried it in my test environment with Asterisk 1.2.1 and Asterisk-Java
0.2.

Here is my code:

TestAGI.java
public class TestAGI extends BaseAGIScript
{
    public void service(AGIRequest request, AGIChannel channel)
            throws AGIException
    {
        // answer the call
        answer();
       =20
        char c =3D streamFile("vm-instructions", "1");
       =20
        System.out.println("got char: '" + c + "'");

        // end the call
        hangup();
    }

    public static void main(String[] args) throws IOException
    {
        new DefaultAGIServer().startup();
    }
}

fastagi-mapping.properties:
test.agi =3D TestAGI

Output on Asterisk CLI with agi debug:
AGI Rx << ANSWER
AGI Tx >> 200 result=3D0
AGI Rx << STREAM FILE "vm-instructions" "1"
AGI Tx >> 200 result=3D49 endpos=3D45760
AGI Rx << HANGUP

Output of the program after pressing DTMF 1:
got char: '1'

[Asterisk-java-users] re: Problem with ConnectEvent

[Brett S. <bs...@no...>]

Here's a technique I use to get arround the problem of trying to send an 
Action when you are in an event handler.
If you don't know; its simply not possible.

The call to 'new RecieveFax(event)' creates its own connection to the 
API Manager.

I do wonder whether it would be better if the MangerEventHandler method 
was called in a seperate thread from that which the ManagerReader runs 
in however that may have other undesirable side affects.
Alternatively the call to SendAction should probably throw an 
IllegalStateException rather than just timing out. As it stand its hard 
to diagnose why the call to SendAction fails.

Basically It's necessary to send the subsequent action in a different 
thread from the the eventHandler otherwise the ManagerReader locks up 
and nothing works. The subsequent actionn should also be sent using a 
separate instance of the ManagerConnection.

You could potentionally send the subsequent action in the event handler 
thread (using a separate ManagerConnection) but you will block the 
ManagerReader from notifying your application of other events and I'm 
not certain, but I suspect that there is little to be gained from 
holding the ManagerReader up whilst you do other work as I doubt that 
Asterisk is waiting on the ManagerReader and as such you really arn't 
doing  the operation synchronously (with respect to Asterisk).

So here is a sample class demonstating one possible solution.

I hope this of some use.

Brett.

[Asterisk-java-users] Sending actions from event handling thread (was: Problem with ConnectEvent)

[Stefan R. <sr...@re...>]

Brett,

thanks for publishing your solution, i am sure it will be of help for
others with similar requirements.

I am currently thinking about the options to fix this for Asterisk-Java
0.3. What I thought about is:
a) using one connection only for event receiving and using a pool of
connections for sending actions
b) separating the reader and the event handling, i.e. there would be one
reader threat that places asterisks output into a buffer and a
threadpool that dispatches the events to the listeners.

There are some issues with both option that I would like to discuss.
Option a) has the problem that multiple connections are needed. Thats
probably fine if you run one central instance to control asterisk but
calls for trouble when using Asterisk-Java on the desktop. Option b) is
better in this regard but no longer guarantees that events are delivered
in the order they are received. This could be adressed by adding a
sequence to the events but places additional burdon on the developer.

What do you think? Are there other options? What would you prefer?

[Asterisk-java-users] Eclipse IDE

[Jonathan A. <jau...@st...>]

This is really just an annoyance and not creating any road blocks.  But,
I am currently using the Eclipse IDE.  One of the things that it reports
is that the AbstractAGIScript and it incumbent methods are deprecated.
It is not creating any problems but does anyone know why it is doing
this and what I can do to correct this problem?

yes you should use BaseAGIScript with Asterisk-Java 0.2 :)
