Abstract: In a method of providing a caller with a pre-stored sound chosen by a called subscriber instead of a standard RBT (RingBack Tone), an HLR (Home Location Register), when a location request message is received from a call-originating exchanger, furnishes either the call-originating exchanger or a call-terminating exchanger with information on whether or not an RBT is to be replaced for the called terminal. The call-originating exchanger or the call-terminating exchanger then searches, while a trunk connection is established between the exchangers, for a sound code assigned to the called terminal based on the information furnished by the HLR, and provides the caller with a pre-stored RBT-replacing sound associated with the found sound code as an RBT.
