Title: Method for interrupting a telephone call after receiving a busy signal

Abstract: A telephone subscriber placing a telephone call through atelecommunications network (10) to a telephone line carrying an existingcall may interrupt that call by entering an interrupt code to the network.Upon receipt of the code, the network verifies whether the interrupt codeis valid by consulting a data base (21) that cross-references interruptcodes to corresponding lines. If the code is valid for the line carryingthe existing call, the network then interrupts the existing call.
