No, there isn't because I did this tests in a non production Linux box with
only that 2 UAC's registered (1919 and 2020).
Thanks in advance.

| Hi Jan,
|
| Thanks for your answer!
| See the attached files (ser.cfg and ngrep dump).
| PS: Of corse I did some modifications in that files just to protect our
| Network.
| If you want the original files I can send to your personal e-mail.
|
| Thanks again.
