The only circumstances that I know where STUN does not help is when the UA is located behind a symmetric nat. In the othre 3 cases of nat, it should help you just fine.

But, let say that every body follows the standars ( JA!, ask cisco ) ... you should not have problems at all.
It is worse than that. The STUN taxonomy is brittle, there are NATs which feature different behaviour than anticipated in RFC3489.
