Is there anything not considered packet switching?

geez... he says the circuit is established after someone says hello... ha.. you can't send the hello audio until after the circuit is established.

Yes, the most common example is the voice network (the PSTN / Public Switched Telephone Network). It establishes a "circuit" for every call, and it is permanent until that call ends. It switches on a "call by call" basis. Every packet associated with that call takes the same path.
It is almost always considered archaic to use circuit switching, it is rarely useful or efficient. It was popular in the "pre-data" era of networking when it was audio and video, generally analogue, going over the path rather than individual packets. Now that we have packetized data and the power to evaluate the route every packet, there is little to no purpose for circuit switching.
