[asterisk-users] Am I cracked?

[Luca Bertoncello]

Hi list!

Very strange...
I ran the Asterisk CLI for other tasks, and suddenly I got this message:

  == Using SIP RTP CoS mark 5

Packet timed out after 32001ms with no response

At the time no phone try to call...
On my Firewall I see a SIP packet coming from an IP in Palestine...
Am I cracked? I think I disabled all "guest" access. How can I check if my
Asterisk allows guest to originate calls?

Thanks
