Abstract

A technique for providing circuit-switched call services for a call stretching between a packet-switched domain and circuit-switched domain is provided. A possible server implementation of this technique includes a first interface adapted to receive packet-switched protocol messages requesting circuit-switched call services, a service component providing the requested call services, and a second interface adapted to pass call control towards the circuit-switched domain after the call services have been provided.
