Maybe I was wrong and needed to take a more holistic approach.
Indeed we could be talking past each other, happens to me all the time!

I was mainly pointing out the differences in backhaul, which in reality are the more important things, air interface is just air interface

So, when concentrating on the air interface, between the UE and BTS, there is not really that much difference between whether the call is CS or PS. All the difference is in signalling; how to establish the routing of the data in backhaul, what codec, channel configuration and data rate to use, etc...

So the question "is CS call always GSM?" is a bit misleading; "GSM" is not a very specific term really.
