Summary:                    [patch] IPv6: System configured for only IPv4 tries
sending to IPv6
Description: 
Running on a dual stack system, with a bind address set to 0.0.0.0
(indicating only IPv4 support), placing a call to a domain that only
resolves into an IPv6 server, Asterisk tries to send anyway with poor
results. This indicates a few things to me:
- Something is wrong in the code, since it doesn't act as documented in
sip.conf. (bindaddr 0.0.0.0 should only get IPv4 support)
- Many log messages are wrong
- Again, like in another issue, Asterisk tries sending SIP messages to a
NULL address. This is a bug in itself.

I have modified the host names in the log, can provide programmer with
proper addresses for testing.

---------------------------------------------------------------------- 
I have an Asterisk 1.8.0-beta4 instance running on Linux with a public IPv4
and IPv6 address.  I tried reproducing this and was unable to.  When
calling another PBX that has a AAAA record, it would only attempt to send
to the IPv6 address if I had configured Asterisk with bindport=::.  It
would _not_ attempt to send to that address with bindport=0.0.0.0.

So, this is looking like it may be a mac specific issue.  If that is the
case, I don't consider it a 1.8.0 release blocker, so I'm going to update
Mantis to reflect that.
