For telephony people, the IP protocol is for a LAN environment
that there is no difference between H.323, SIP, TELNET, or DNS
for that matter.

So?
As I said:

some protocol is necessary between two telephony networks.
FYI, there is a protocol called TBGP proposed in IETF for the purpose.

So, you are saying SGCP/MGCP are wrong to use 323.
Fine.
FYI, in my design of "The Simple Internet Phone":
If you are interested in Internet telephony, see you at
INET'2000 in Yokohama for the presentation of our paper
"The Simple Internet Phone".
I chose to keep using 164 (sorry, not 42) at least for the time being,
because it is the easiest way to let subscribers replace telephony
network with the Internet.
