Abstract: A method and a system for managing communications sessions, in accordance to events that occur in either one of a telecommunications network, such as the PSTN network or a mobile telephone network, and a data communications network such as the Internet is provided. The system includes a service logic controller supporting a data structure that holds a plurality of communication session disposition program entries. The service logic controller connects with the telecommunications network and with the data communications network through respective gateways that transmit communication session disposition inquiry messages. In response to those messages, the service logic controller retrieves the appropriate communication session disposition program and generates from that program an instruction to the entity that originated the inquiry message. The communication session is then processed according to the instruction.
