Some IP networks are pure telephony networks.
Only one IP network in the world is the Internet.

He is not saying anything meaningful.

The context is that Yixin said something about S/MGCP and 323 and
Chrisitian acknowledged. I know the relevance is meaningless.

You seem to have no knowledge on INET and IETF.
Signature of Vint will be a good starter for you.
Or, ask someone who knows something about not only IP networks but
also the Internet.

We, IETF, are for the Internet, not merely IP.
