| Description: | I'm seeing messages such as: Aug 23 21:40:58 pbx local0.notice asterisk[5760]: NOTICE[5794]: chan_sip.c:21372 in handle_request_invite: Call from '' to extension '000441412950184' rejected because extension not found in context 'INVALID'. and sometimes several hundred of them in a few seconds, but no IP address is given so that I can throw up a firewall block. Since this is an indication of a possible attack, more information should be included to assist in identifying that attacker. | ||
