[asterisk-users] Help with Sip Registration

[Treesa Fairy Joseph]

Hi all,
    I have installed X-lite client on a windowsXP
machine and asterisk on an enterprise linux m/c.
The client is sending a registration message to asterisk
server. It is able to process the message and sends 200 OK
back. But later it says "Scheduling destruction of sip 
dialog xxxx ". Then it says "Really destroying sip 
dialog xxxx". What to do for this problem??? I had
enabled the sip debug at the asterisk. I have pasted
the messages, I got below. Please help me in solving the
problem. 

Thanks in advance,
Treesa
