ABSTRACT:
The present invention relates to a method for providing an arbitrary sound chosen by a called subscriber for a caller instead of a conventional RBT (RingBack Tone). The present method comprises: the first step, conducted by an HLR (Home Location Register), of furnishing a call-originating exchanger with information on whether to replace RBT or not for a terminal if a location request message is received from the call-originating exchanger when a call connection is requested to the terminal; the second step, conducted by the call-originating exchanger, of requesting a trunk connection to a call-terminating exchanger, and further requesting another trunk connection to a sound providing means based on the information and preset routing information while furnishing the sound providing means with information to identify the terminal; and the third step, conducted by the sound providing means, of selecting a sound based on the terminal identifying information, and providing the selected sound for a caller instead of an RBT.
