Yes, multiple times. Cortona is a UNSC serial AI; she is a smart AI created by the ONI, a branch of the UNSC, to provide in-field assistance and information to soldiers. She was assigned to Master Chief due to the restraints of the Cole Protocol, and has contacted the UNSC before and after she was assigned to Master chief. If you are talking about Halo 3, Cortona did not directly contact the UNSC. She left a message fragment in the crahsed flood-infested ship, and occasionly contacts the Master Chief. When she was rescued by Master Chief, she helped out the UNSC until Master chief and the Arbiter escpaed the replacment Installation 04 (the Halo destroyed by Master Chief in the first game). She did send a beacon at their location when the UNSC frigate "Forward unto dawn" was cut by the slipspace portal's collapse, but she did not directly contact the UNSC when Master Chief went into cyrosleep either.
