Narrative:

ZME cleared us from FL330 to FL290. Call was acknowledged and descent began. Passing FL305, memphis asked us to confirm level at FL310. I told him (mem) that we were cleared to FL290 and he told us to level at FL310. We climbed back to FL310. Nothing else was said. However, ZME controller seemed very confused. He was mixing up call signs left and right.
