That would work at the RTP layer.  That could flow down to the UDP
flow, but resumption is non-trivial.  If you lose the NAT bindings as
a result, you would have to be prepared to restart the flow.  The
(previously) active flow might simply have to represent the highest
priority candidate pair in an ICE reboot.
