Hello All
I need your help please
[Jan 14 13:03:36] NOTICE[2923]: chan_sip.c:15032 handle_request_invite: Sending fake auth rejection for user sip:1001@IP;tag=190364702
Usually I can block the IP in Iptables but this shows it coming from ip 0 0 0 0
0.0.0.0 1001 474473836-1 00101/00002 0x0 (nothing) No Rx: INVITE
What can I do to block this?
I tried adding ip 0 0 0 0 in iptables to block it but it didnt work.
The domain part of the From header URI is not really useful for security purposes.
0.0.0.0 is not a valid IP address. It is used as an indicator of a held stream in SDP, so could not be used reliably in SIP, even if your routers allowed you to route to it.
