With G.711 and 20ms voice samples, with IPv4 you get:
20 bytes IP + 8 bytes UDP + 12 bytes RTP + 160 bytes payload 20% overhead.
Now with IPv6. Say we use shim6 or something like that to implement multihoming too. The shim6 header isn't decided yet, but I suppose it's got to contain at least a pair of addresses (32 bytes).
40 bytes IP + 32 bytes shim6 8 bytes UDP + 12 bytes RTP + 160 bytes payload 36.5% overhead
hey! we charge by the byte. so ipv6 is looking better and better!
