The provisoining rule is under the Voice/ Admin section, this is a small trap, you must click admin to get to the voice provisioning section,
The reason you have to power cycle the device after you put the rule in is that by default you will see the resync period , which you see in Coffeebarons image is that this timer set for 3600 secs (1 hour), so it won't try to pick the configs up for an hour so a power recycle forces it to pick it up almost straight away.
