[Asterisk-java-devel] How to receive "No route to Host / Network Disconnection / ..." events?

From: Jose B. <pe...@gm...> - 2014-07-25 11:22:10

Hello!

How can I get network errors events sent by asterisk-java library?

I would like to check a few variables after one of those errors occur, to
know if Asterisk failed or it was just a network hiccup.


Thank you.

Could you please go a bit more into detail?
which "network errors events" are you talking about?

Oh, sorry for asnwering so late. I was looking into my logs to copypaste
those errors...

Asterisk-java is running on 1 machine and Asterisk-AMI is running on other
machine (IP 2).

If network fails, or Asterisk fails or IP-2 machine freezes, asterisk-java
throws these errors because it cannot connect to Asterisk:

How could I retrieve those warnings in my Java code? I would like to run a
few checks on Asterisk.

If Asterisk failed it means audio calls have all finished and I must
cleared a few variables in Java.

Hi,

you should be able to catch a DisconnectEvent if you have a Listener 
attached. This event is fired whenever the connection to your asterisks
breaks down. On a successful reconnect you will receive an ConnectEvent.
In my experience, AsteriskJava only detects a failure, when you try to 
send a Command or an Action... as long as you do nothing, AsteriskJava
thinks, it´s connected and the ManagerConnection.getState() always 
returns "CONNECTED"... at least for a very very long time.
  So, if you depend on "almost-realtime" Event for Network-Failure 
beeing fired, you should periodically do some action on your
ManagerConnection... e.g. in a Thread.

I thought Asterisk-java used sort of a keepalive to Asterisk (sending
"ping" action).

I'll add it in my program then.

Thanks for the tip for using a Thread. :)

There is a ping thread but you have to use it explicitly:
