Nortel Networks introduced a new Media Processing Server (MPS) 500 designed for Integrated Voice Response (IVR) applications at medium-sized contact centers and small service providers. The MPS 500 media processing server enables customer call centers to provide speech-enabled, self-service support. Nortel Networks said it also plans to offer service creation capabilities with the MPS 500 that will provide a dual application development environment supporting the PeriProducer GUI and Voice XML.
