Kamailio tries to use the socket where the request was received for
sending out as well. So it should just work in most of the case.

Anyhow, you can test the address family for received request:

if(af==INET6) {
  # force an ipv6 socket
  # set $du to an ipv6 address
} else {
  # force an ipv4 socket
  # set $du to an ipv4 address
}

Cheers,
Daniel
