They are all still there. Is one of the buttons you have available during a call named "Unlock"? If so, just click on the "Unlock" button, then all the buttons you are looking for will be available. They are just "hidden" because the phone is in a semi-locked phase when you receive a call.

If you are initiating a call, just click on the left soft-key, "Call Status". The button you are looking for are there.

Sorry, I don't have any screen prints for you. Hope this helps.
