Hi All,
I'm using java fast-agi protocol,
and I'm dialing to new destinations based on the existing channel:
*
channel.exec("Dial","SIP/extension1")*
and I'm facing a problem to cancel that dial if the call sufers a timeout,
and originate new call to other destination. Do someone have faced that
problem or have any idea to implement this scenario?
I'm working with the versions below:
asterisk 1.6.2.22
asterisk-java 1.0.0
Thanks in advance!
Jeryes

Hi,
happy new year, welcome to the list and congrats... you´re the first in
2012!
reason enough for me to flood you with solutions, but....
you gave too little info...at least for me...:
- a few more lines of code would be helpful... full code would be best +
part of the dialplan where you call the agi..
- what is your objective?
- any exceptions / interesting logs?
- how do you define timeout? I don´t see any at your dial command.
- what did you try so far and what was the result?
regards,
yves

Hi Yves,
Happy new year and thanks for your quick reply!!
Actually, I fixed the problem, sorry it was my fault...
I'm working on an application based on fast-agi, and I've created an
AsteriskServer that implements the interface BaseAgiScript, to receive and
process calls from Asterisk.
After receive a new call, the application dial to some destination (e.g.
user1), and in some situation, like timeout of dialing, the application
must cancel that Dial and
create a new one to other destination, but I was doing in a wrong way, I
was looking for a way to Cancel the Dial, and I guess that I can't do it,
so I fixed the problem adding the timeout value in the Dial command, now
the Asterisk is sending that Cancel when the timeout expires, and it's
working:
Example code of implementation:
public class AsteriskServer extends BaseAgiScript
{
/**
* The service method is called whenever AgiAsteriskServer receive a new
* incoming AgiRequest.
*/
public void service(AgiRequest request, AgiChannel channel) throws
AgiException
{
//Some code
try
{
channel.exec("Dial", "SIP/user1, *20*");
} catch (Exception e) {
//do something
} finally {
//do something
}
//Some code
}
}
and *20* is the timeout to that destination.
Now I'm facing another problem, the command Dial is not running on
background, it keeps the Thread that executed the command in wait until the
Dial sufers some dinconnection event (4xx, 5xx or 6xx)
So do I need to create a new Thread to execute the command Dial?
And is there another way besides the CLI to originate a new Call using
fast-agi?
Thank you!!
Best regards
Jeryes

Hi,
unfortunately I do not understand you fully.
What do you mean with "sufer"?
What is the Event 4xx, 5xx ...?
Please explain. And explain exactly what your
Objective is. When To call who, And so on.
I dont understand what you mean by cancel
the dial on timeout...? After a timeout the dial IS
finished... cancelling for me would be something
like interrupting a running dial command.
At First Reading it Looks like you're needing
Something like a Queue...? Or an IVR?
Regards,
Yves

Hi Yves,
I'm sorry, it was a little confusing... Let me try again...
I'm working with fast-agi, implementing
org.asterisk.java.fastagi.BaseAgiScript.
Yes, I have an IVR, that receive a call (input channel) originated by some
owner, the application basically plays a file and then dial to some
destination, if that destination doesn't answer in 20 seconds (timeout),
the IVR must dial to another one. I did that using the command Dial, and
setting a timeout in that dial:
int resultCode = channel.exec("Dial", "SIP/user1, *20*");
That is the way i found to establish a new outgoing connection on a
channel, and then link it to the existing input channel.
The problem that I am facing is to distinguish a timeout event from the
disconnection of the owner, in other words, how can I differentiate when
the FROM leg disconencts (sendig the CANCEL Request) from the timeout of
the TO leg ou if the TO leg ignore (by replying 480, 486, 500, 503 or 603
for example) a call that is in DIALING state?
Thanks for your time!!!

I see.
Try to implement a listener that listens to the asterisk-events. If you
receive an unlink or hangup event,
check, if the corresponding channel is your agi-source channel and if
so, interrupt the outgoing dials,
that were originated from here..
if your source channel is hung up, do not execute any commands on this
channel as it would end
up in an exception...
regards,
yves

Yves, " if your source channel is hung up, do not execute any commands on this channel as it would end up in an exception..." that worked... if the channel is alive no exception will be thrown, and that is the characteristic of the FROM leg disconnection, or a disconnection of an established call, otherwise it is a timeout or an ignore sent from the TO leg. Thanks for your help!! []s Jeryes 2012/1/5 Yves A. <yv...@gm...> > I see. > Try to implement a listener that listens to the asterisk-events.

Sure... but a listener would be more elegant, I think... yves Am 06.01.2012 17:34, schrieb Jeryes .: > Yves, > > " if your source channel is hung up, do not execute any commands on > this channel as it would end > up in an exception..." > > that worked... if the channel is alive no exception will be thrown, > and that is the characteristic of the FROM leg disconnection, or a > disconnection of an established call, otherwise it is a timeout or an > ignore sent from the TO leg. > > Thanks for your help!! > > []s > Jeryes > > > > > 2012/1/5 Yves A. <yv...@gm... <mailto:yv...@gm...>> > > I see. > Try to implement a listener that listens to the asterisk-events. > If you receive an unlink or hangup event, > check, if the corresponding channel is your agi-source channel and > if so, interrupt the outgoing dials, > that were originated from here.. > if your source channel is hung up, do not execute any commands on > this channel as it would end > up in an exception... > > regards, > yves > > > > ------------------------------------------------------------------------------ > Ridiculously easy VDI.
