[Asterisk-java-users] Ami freezes on error -> Sending DTMF to zombie channel

[Jorge <gus...@gm...>]

Hi:
I have seen an error that is quite strange. I am connecting to Asterisk
using asterisk-java-1.0.0.M3.jar on this way :

ManagerConnectionFactory factory = new ManagerConnectionFactory(url, user,
pwd);
        managerConnection = factory.createManagerConnection();

        asteriskServer  = new AsteriskServerImpl(managerConnection);
         try {
            managerConnection.login();

After that it connects well. I see the connection in the Asterisk CLI and I
am able to send commands. I have seen that when I try to transfer a call
and, at the same time, send DTMF tones it crash. I think this behaviour is
normal because I am tryinig to send DTMF tones to a Zombie channel. The
problem here is that the connection between Java and Asterisk is lost. I am
using PingThread and it says that it is not possible to reach the AMI but
when I see the Asterisk cli using "*manager show connected"* I see the
connection between Asterisk and Java, but the connection is not there
because of the PingThread error.

This is the error I got. Could you let me know if  there is a way to
maintain the connection with the AMI? Is it normal losing the connection?.
Theoretically the AMI connection is maintained throw  a process that tries
to reconnect. What is going on here?
