If they didn't tell you when you called, they probably won't tell you when you call back.
Some schools policies in place where they cannot/will not share a decision over the phone, whether it's good or bad.
And some schools may call acceptees, but they may not tell you over the phone that you're rejected (I'm absolutely not suggesting that you didn't get in, I'm just giving it as a possibility, especially in light of UVA and Duke and other schools that specifically call admits, but don't call/notify by phone waitlists or rejections)
