I'm interested in this as well. I tried binding Asterisk to both IPv4 and IPv6 addresses, but Asterisk keeps printing the following warnings WARNING[3542]: chan_sip.c:3183 ast_sip_ouraddrfor: Address remapping activated in sip.conf but we're using IPv6, which doesn't need it. Please remove "localnet" and/or "externaddr" settings. I need localnet and externaddr for IPv4 clients behind NAT. I also want IPv6 support for clients that support it. It seems that it is not possible to run Asterisk in a dual stack configuration and support clients behind NAT.
