unable to make a call about red5phone HOT 5 OPEN

I have the same problem. Did you solve this issue?

Seems like I'm hitting also the same problem. Are you running on Linux/Ubuntu?

For me, everything works fine when Red5 is on Windows. But when I move it to 
Ubuntu, 
REGISTER works but when I make a call I get the following,

600 is my echo test application....I just hear ringing but on my Asterisk 
console, I 
can't see the call coming in.

It seems that Red5 hangs when the RTMPClient tries to connect back (loopback) 
into 
the sip application.

After a while, Red5 disconnects the RTMPConnection...

And Red5 server hangs/dies...can't connect any client to it anymore.

Anybody care to share there experiences/findings?

I'm running on Open SUSE Linux, but on Windows it works fine.

I rebuilt Red5 and Red5Phone on Linux SUSE and Ubuntu, but I'm still facing this
problem. 

I think the problem is here starting in line 142 of RTMPUser


        try {
            connect( host, port, app, this );

            //while ( !startPublish ) {
            //   Thread.yield();
            //}
        }
        catch ( Exception e ) {
            logger.error( "RTMPUser startStream exception " + e );
        }

There is no need to wait anymore after a connect.
