  • Patent number: 9008297
    Abstract: Methods, computer program products, and systems for providing called party initiated priority marking are provided. The method includes receiving a request from a called party to mark a telephone call currently in session as a priority telephone call. The telephone call is initiated by a calling party and received by the called party. It is determined if the called party has authorization to mark the telephone call as a priority telephone call. The telephone call is marked as a priority telephone call if it is determined that the called party has authorization to mark the telephone call as a priority telephone call.
