Telecommunications networks are today in the process of changing, converging, and being remade more radically than at any time in their previous 135 year history. Wireline, wireless, and cable networks - which have traditionally been different in terms of their components and protocols — are converging to utilize similar signaling and media handling approaches, and SIP (Session Initiation Protocol) is at the center of it all as the predominant next-generation signaling protocol. With support for mobility, all media types, and its similarity to traditional web protocols like HTTP, SIP is a service-friendly signaling protocol upon which all next-generation telecommunications services will be built in the future.

The Xpress Service Creation Environment (SCE) is a Windows-based GUI application that allows users to quickly and easily create multimedia communication services for next generation IMS, converged TDM/ IP, or pure VoIP networks.

The PT SIP Services solutions set provides the service creation and service deployment products that carriers need to rapidly build and deploy SIP-based services. The product set includes a graphical service creation environment (SCE), an extensible and highly scalable application server (SIP Xpress Server), and a high performance software-based media server capable of IVR and conferencing. With these products, carriers can quickly create and deploy the new media-rich applications that subscribers are looking for from next-generation networks.
