Sound interrupts for some seconds when another client logs in

[GoogleCodeExporter]

Hi!
I have a problem with red5phone from sip_47 archive.

It's working perfectly, sound is good, but I have one problem:

1. Let's say i call through red5phone to answering machine. I hear sound, it's 
good.
2. When I'm listening to the sound another red5phone is connecting to red5. 
Exactly at this time my sound interrupts for some seconds and I see [SipUser] 
provider.halt message.

Please help!

I was wrong a bit in describing the situation.

Here is the scenario to reproduce the bug:

1. Open red5phone in 1st browser window and place a call to somewhere (for 
testing answering machine is better).
2. While listening the voice  open another window with red5phone and register 
to the same server.
3. [b]Reload second window[/b] (or just close it) and the sound coming from the 
first red5phone window interrupts for some seconds. After that it continuous 
normally.

Here is red5 output after reloading second window:

Seems i have fixed this bug.
I have commented strings
// new Thread().sleep(3000);
and 
// sip_provider.halt();
in SIPUser class, function close()

I still don't know what exactly interrupts the sound, but with this fix it's 
working smoothly.

If anybody can explain what that strings do i'll be very grateful.

...we are experiencing exactly the same issue using the sip_r54 release.
What is the reason to sleep all the threads for 3 seconds??

I think this is a major issue to be fixed as soon as possibile.
Could anybody explain what is the purpose of the following code lines in the 
Red5 SIP Stack?

new Thread().sleep(3000);
and 
sip_provider.halt();

Thank you in advance for any clarification and support...

Some updates from my experience...

1. The real problem is at
org/zoolu/sip/provider/SipProvider.java

Sound interrupts when it tries to halt tcp_server.
If we are using udp transport, we can comment starting and stopping tcp 
transport.

2. The second problem is too big delay in new Thread().sleep(3000);
200 would be more than enough, and with this value there's no sound 
interrupting.
