No, when the phone is powered off, it is not expected to ring. When it
is suspended it is expected to ring.

I assume you mean high power state not low power state, or does low
power state mean early-suspend state. If so, locking a wakelock will
accomplish this.

If you mean this as a general strategy, and not a specific outcome,
then it does not always work (for the reasons I have already stated).
