Abstract
A method for communication in a communication system includes predefining a plurality of service delivery modes having different signaling and media path configurations in circuit-switched and packet-switched networks. A request to place a call is accepted in the circuit-switched network, and a call service to be provided to the call by a service platform in the packet-switched network is identified responsively to the request.
A service delivery mode is selected from the plurality responsively to an attribute of the call indicated by the request. Signaling and media paths are established for the call via the circuit-switched and packet-switched networks in accordance with the signaling and media path configurations of the selected service delivery mode. The call service is provided from the service platform to the call using the established signaling and media paths.
