we have a hosted PBX and we keep getting probed by the following
[Mar 20 11:30:48] NOTICE chan_sip.c: Registration from '"100" <sip:100@*.*.*.*:5060>' failed for '220.127.116.11' - No matching peer found
so we need to block the 64 address on the firewall
can somebody show us how to block all protocols for the address?
