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.
