I'm not sure you understood correctly, so I'll explain things in another
way.

Imagine you have a network for which many packets arrive out of order
and that it takes 200ms approximatively to get all packets and be able
to play them. If you the jitter is < 200 ms, the voice will be
scrambled, if the jitter is > 200 ms, you will just have enough time to
put things in the right order.

Theorically you can always put a jitter big enough to be able to have a
correct voice quality, but a delay of more than 500ms is not acceptable.
