Re: [Asterisk-java-users] asteriskServer.getChannelByName Timeout waiting for events from StatusAction

[Yves A. <yv...@gm...>]

Hi,

so... if this is not a human call and all you need is call to or receive 
a call from such a device and kind of control it via dtmf, then I would 
recommend to use an (java-) agi-script.
For an incoming call you route the call to your script and the device is 
connected to the channel you control with your agi... as long as your 
script or the device hangs up.
For an outgoing call just initiate a call between your extension that 
routes to the agi-script and the extension / number you have to dial to 
reach your device.
within the agi you have access to the channel and can directly send or 
receive dtmf-tones.
if you want to use java agi scripts, take a look at the docs for 
asterisk-java. there is a tutorial. java-agi is really great... see it 
as some kind of a java-dialplan.
the only annoying thing is that you have to reload the agi-server each 
time you modify your agi-classes, as they are cached... I wrote a 
wrapper that allows me to write
java-agi in a text-file that are executed in realtime... so i dont have 
to compile and deploy them anytime... just change the script and without 
reloading the server the
changes immediately become applied in the next run...
