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