Abstract: A communications network configuration for delivery of multimedia services comprises a packet network to which a plurality of terminal devices are connected, a service provider network for providing multimedia services to the terminal devices, a virtual circuit switched network intermediate the packet and service provider networks, and a gateway distributed over the circuit switched network. The distributed gateway comprises a client application unit interfacing the circuit switched network to said packet network and a virtual channel interface unit interfacing the circuit switched network to the service provider network. The client application unit binds logical channels for a multimedia call to association tags for respective virtual channels of the circuit switched network and forwards said association tags to the virtual interfacing unit.
