The present invention includes method and systems, and communication terminal, for transmitting a variety of information and contents (Ring-Back Information) such as music, songs, advertisements, sounds, voices, any audible resource edited by the subscriber, animation, and moving images, instead of the uniform ring-back tone (an mechanical tone) which has been provided to a calling party while the calling party is waiting for the called party's answer after the calling party executes a call setup request. According to the invention, the Ring-Back Information selected by the called party is provided to the calling party by inter-working of the terminating exchange 10 -n and the terminating terminal 20 -n. When the terminating terminal 20 -n receives a call from the terminating exchange 10 -n, the terminating terminal 20 -n transmits the Ring-Back Information to the terminating exchange and then the terminating exchange 10 -n delivers to the originating terminal the Ring-Back Information received from the terminating terminal 20 -n.
