Hi all

I`d like to know if someone already saw this situation. I wrote the log from ACC table below.
I

You can see the second INVITE. The proxy received it one second before the BYE. I think it is impossible. I already tried to simulate 
this case again, but these errors never happens with us (Murphy really exists). So, I ask you any comment about this weird situation. 

Thanks.
