|Description:||I'm seeing messages such as:|
Aug 23 21:40:58 pbx local0.notice asterisk: NOTICE: 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.

This should be fixed already. I ran into the exact same situation and made a patch and got it committed on 31-May-2011.
