Summary:                    Bad assumption in ast_ouraddrfor in chan_sip
regarding extern IP and IPv6
Description: 
The code says:


if (ast_sockaddr_is_ipv6(&theirs)) {
                if (localaddr && !ast_sockaddr_isnull(externaddr)) {
                        ast_log(LOG_WARNING, "Address remapping activated
in sip.conf "
                                "but we're using IPv6, which doesn't need
it. Please "
                                "remove \"localnet\" and/or \"externaddr\"
settings.\n");
                }


Which is definitely wrong. If you have "::" as a bind address, the IPv6
socket *WILL* listen to IPv4 and the externip/localnet settings might be
needed on the IPv4 side of life.
