  Not yet, though Maxim's RTP proxy supports the translation.

  I hope so (It has been on my todo list for a while, but with low
  priority).

  This will probably not work, the problem is that in this scenario you
  would have to translate REGISTER contacts as well. That means you
  would have to encode the original contact into an IPv6 one and then
  decode it when a request comes for the UA. Mangler can do it, but it
  probably doesn't support IPv6.
