Literatura académica sobre el tema "Software Asterisk"

Asterisk is a leading open source telephony software/system, easily implemented over intranet and internet. Asterisk empowers developers and integrators to create advanced communication solutions. An Asterisk system is a low cost type of a traditional PBX system. Any phone controlled by an Asterisk system can call a VoIP or analog phone controlled or managed by a traditional telephone system or by Asterisk telephone system. In this paper, the authors focus on the deployment and testing of various Open Source Asterisk Services in an enterprise level communication system. Selected services are listed in this paper that can be used to implement a telephone system with good Quality of Services (QoS) and good Quality of Experience (QoE) from the personal user to enterprise level users.

The authors outline the potential of sensor technology for people with disabilities and those people with motor disabilities in general. First the authors describe how people with disabilities interact with the environment using specialized Assistive Technologies (AT) to interface modern Information and Communication Technology (ICT) via the standardized Human-Computer Interface (HCI). The authors discuss the state-of-the-art and emerging sensor technology and how it enhances the potential of AT facilitated interaction with ICT/HCI regarding two domains: a) Sensor technology embedded in the environment providing flexible and adaptable means of interaction and b) sensor technology for better, more flexible and efficient application of skills of people with disabilities as AT solutions. Based on this analysis the authors advocate for changing AT practice in terms of assessment and service provision, but also R&D to recognize the extended potential provided by sensor technology to exploit presently unused or neglected skills of users. The authors underline the need to make AT solutions more flexible, adaptable, and affordable. the authors argue, in view of the potential of sensor technology, that there is an increasing need for an efficient software framework allowing an easy integration of sensor technology into AT solutions or even individual AT service provision. Finally the authors present the AsTeRICS framework as an example of an extendable AT construction set for an open source and crowed sourcing approach for a more user-centered, easy, fast, and economic implementation of sensor based or sensor enhanced AT solutions.
