Abstract: A call from a calling party to a first called party in a telecommunications network is initiated via a network switch. Subsequently a leg of the call from the network switch to the first called party is released. Data identifying a second called party is transmitted from the first called party to a network control platform. The network control platform correlates the data transmitted and the respective call earlier made and controls the network switch to now route the earlier call to the second called party.

Abstract: An intelligent peripheral (IP) (3) in a telecommunications network is operated under the control of a service control point (SCP) (5). Control messages conforming to a standard control protocol, which may be INAP--the Intelligent Network Application Protocol, are passed from the SCP to the IP which then executes a predetermined function. Some of the control messages include a field identifying the messages as relating to an additional function not provided for in the standard protocol. In response to such a message the IP executes the relevant additional function instead of one of the standard functions.
