Please note that if V4 is talking to V6, you need some inetrmediatory

Be it proxy or ICE..etc. Please note that if V6 node only talks in V6

There is ANAT RFC for SDP format in case of dual stack and also there is
another ICE based SDP implementaion for SDP format.
But i think ANAT RFC (4091) must help.
