Summary:                    Bad DNS lookups on ENUMLOOKUP - various problems
Description: 
1) ENUMLOOKUP apparently is doing an "A" record lookup on the domain in the
From: header.  Why is this?  It's bad, slow, and leaks information.  Should
not happen; no reason for it to happen.

2) Failures on ENUMLOOKUP on NAPTR records on ISN-style lookups.  The
lookups just outright fail, though the DNS returns the correct NAPTR back
to Asterisk.  Not sure if this is an ISN-style problem or if this is an
issue with all NAPTRs.

James: You are correct in your comments about the first issue ("A" record
lookups).  The INVITEs are coming from devices which do not have a peer
entry defined; they are being associated with the [general] settings in
sip.conf.
