Summary:                    Unable to use IPv4 addresses for a TCP host when
using IPv6
Description: 
This is kind of a weird edge case, and I think I might know why it's not
working.

I'm trying to "front end" my 1.6.2.10 Asterisk instance with Asterisk
1.8.0-beta4 for testing purposes and to allow IPv6 connectivity.

This is done on the same box.

The error I'm getting is the following:

..........SIP channel loading...
[2010-08-25 11:19:44] ERROR[20813]: netsock2.c:245 ast_sockaddr_resolve:
getaddrinfo("127.0.0.1", "(null)", ...): Address family for hostname not
supported
[2010-08-25 11:19:44] WARNING[20813]: acl.c:564 resolve_first: Unable to
lookup '127.0.0.1'




If I switch host=[some_ipv6_address] on the peer, the error goes away.
When using an IPv4 address, I get that error.

I've disabled srvlookup=yes and dnsmgr without success.

If I understand this right, the 1.8 instance will be talking over IPv6 to
the outside world, and over IPv4 to the 1.6 instance, right?

Therefore, it cannot be bound to just an IPv6 address. This would prevent
it from talking to the 1.6 instance over IPv4.

As indicated in the comments in sip.conf.sample, you need to set
bindaddr=:: to be able to use IPv4 and IPv6 simultaneously.

Can you please try that and report back?
