If it is an incoming call the call will end if they hang up. If you initiated the call then you need to end the call manually for it to end right then. This is usually the case even with 2 landlines, or at least used to be.
I remember that you could tie up someone's phone indefinitely (or until the switchboard cancelled it) if you knew a trick to get free calls from phone boxes, dialled them and left the phone box off the hook.
Lock screen shortcuts, mentioned above, are great. I have phone, camera, internet and calculator.
For a first time Smartphone user I highly recommend going to youtube and searching on Note 2 tips and tricks. Cursed4Eva does some very in depth reviews/tutorials on Samsung phones.
