“…In case of SIP, these services act as a Simple Client on the one side and like a SIP gateway on the other side of the communication pipeline. A detailed description of this protocol translation and its implementation considerations can be found in [23].…”

Currently, more and more enterprises adopt the Voice over IP (VoIP) technology to replace their traditional circuit switching infrastructure in order to reduce the cost of their telephony services. The most frequently used VoIP solutions are made up of stand-alone software -usually complex and requiring extra hardware in a local area network. Some VoIP service providers offer Website based or plugin based solutions, which are, however, difficult to integrate with other applications by the end user.Web services provide functionality over the Internet using various standards like XML and HTTP, independently of the operating system and programming language. In this paper, we propose a framework for Voice over IP based on Web services. Service providers using this framework can offer their customers a protocol-neutral Web service interface, thus enabling the deployment of a general and integrated VoIP solution. Because of the simplified logic, a client in this system is easy to implement and can communicate with clients in other systems without additional local hardware for VoIP.

“…This section provides an overview of this approach and the resulting architectural design. Details and related work will not be discussed in detail, they have been published previously and can be gleaned in [7,8,9,10,11,12]. Basically, the benefits of the architecture compared to existing H.323 or SIP-based solutions or products like Skype [13] are the open and service-oriented approach and the migration from client code into distributed services.…”

Service-oriented architectures foster the interaction of a multitude of different services. In order to ensure flawless service interaction a directory service is needed that can be used to find suitable services for a desired task. A centralized solution for local services might be suitable for small systems, but on a larger scale -when systems start to interact via Federations of Trust -the need for an highly available and easily maintainable directory service arises.
