[asterisk-dev] Better logging for SIP attacks

[Philip Prindeville]

I'm looking at the following:

Jul 15 16:39:31 pbx local0.notice asterisk[5760]: NOTICE[5794]: chan_sip.c:21372 in handle_request_invite: Call from '' to extension '000442070661000' rejected because extension not found in context 'INVALID'.

Should more information be logged with this?
