Up 1 hour and already got SIP scanned

The host below is scanning all extensions up to 9999.  Looks like the
ACL is configured correctly so this is not allowed.

zoo:/var/log/asterisk# cat messages |grep '"11"'
[Feb 19 12:24:26] NOTICE[21123] chan_sip.c: Registration from '"11"<sip:11@>' failed for '' - Device does not match ACL
