[asterisk-users] Asterisk failed to authenticate device - attack attempt.

[motty cruz]

Hi all,
I continue to see the following msg on my Asterisk log:

[Sep  8 15:34:37] NOTICE[7375]: chan_sip.c:23277 handle_request_invite:
Failed to authenticate device 9009<sip:9009 at 196.107.xx.xx>;tag=8dd48dd2

IP: 196.107.xx.xx is my asterisk server IP address.

I don't know what it means and how to cover any holes that attacker is
trying to exploit.

Thanks,
Motty
