Hello, I continued to see this errors in the logs:
[2015-12-02 10:05:57] NOTICE[19949]: chan_sip.c:23277
handle_request_invite: Failed to authenticate device
100<sip:1...@xx.xx.xx.xx>;tag=10cdeaf7
how do I guard against this kinds of attacks? Also, to get the IP
address from where this attack come from I use the following command
"tcpdump -lni eth0 -f "udp port 5060" is there an easy way to get the
attacker's IP?
Thanks,
Motty
