Abstract
In a method for providing an arbitrary sound, chosen by a called subscriber, as a ringback tone to a calling subscriber through a call-originating exchanger, the call-originating exchanger requests a trunk connection to a sound database server based on first information on whether or not to replace an RBT (RingBack Tone) and second information on a route to the sound database server that are received from a home location register (HLR), and provides a called subscriber identification for the sound database server. Then, the sound database server searches its database for a sound specified by the called, and provides the found sound for the caller instead of a conventional RBT via the originating exchanger connected through the requested trunk connection. The caller can hear a sound specified by the called instead of the conventional RBT.
