Is this correct ? Am I missing something fundamental ?

My suspicion is that the RTP traffic isn't traversing the NAT properly. You may have to configure the routers at both ends to forward the RTP packets to the correct destinations. There is a good discussion of NAT on the wiki. One of the great advantages of IPv6 is that NAT goes away altogether. I've been achieving quite reasonable call quality even across IPv6-over-IPv4 tunnels.
