The new generation of Telephone Centers coincides with the term Voice over Internet Protocol (VoIP) term. This term is associated with broad range of protocols, technologies and services that are implemented under a common platform. The aim of all new generation of Telephone Centers focuses on increasing productivity in businesses. Telephone infrastructure is rapidly transforming to tools capable of increasing and optimizing employee's performance. Until recently, the telephone center was just a "clever" machine capable of routing telephone conversations and to serve certain common voice communication tasks. As time and technology advanced, communication needs changed rapidly. The way that humanity communicates today changed dramatically compared to last decade. The form of communication transformed along with common business habits and the necessity to improve all communications in terms of time management, costs, speed and freedom from a conventional office. The telephone device, electronic mail, fax and answering machine serve users wherever they are. The social networks are an integral part of all modern mobile devices. Not only do "Smart" telephone centers know the location of a user and his preferred device to receive calls but also support him to organize his time by setting up a teleconference, instead of taking a long trip to an actual meeting. It's a fact that all the technologies that surround such a telecommunication tool render it very user friendly. However every coin has two faces. The construction, implementation, and installation standards are radically changing as such this complex mechanism can hide risks. A seemingly common setting on a telephone center does not guarantee risk free operation. In respect to all these technologies that lay behind such a complex mechanism, which is nowadays connected to the internet, all configuration procedures must target to a problem free and secure operation.
