A system and method of service provisioning in an integrated telecommunications network (402) having a packet-switched network portion (PSN) (102) and a circuit-switched network (CSN) portion (404) with a gateway (108) disposed therebetween. A service node (408) comprising a Service Control Point (SCP), a Service Data Point (SDP), or both is provided with an interface operable with the PSN portion (102). A first entity (e.g., served entity) is capable of accessing the service node (408) for the purpose of invoking a service. A return result (706, 726) from the service node (408) is provided, based on the decision of what action is to be taken with respect to the service request (704, 724), to the first entity which then determines how the action is to be effectuated. An indication is thereafter provided by the first entity to a second entity (e.g., re-routing entity) preferably using H.450.X messages. In response, the second entity (i.e., re-routing or switching entity) takes an appropriate service action based on the return result obtained from the service node (408). In a presently preferred exemplary embodiment, legacy service nodes built on the basis of WIN/IN service architecture are utilized for the provisioning of Value-Added Services (VAS) or Supplementary Services (SS) in VoIP networks operable with the H.450.X Recommendations.
