Internet Telephony Over Wireless Links
Internet Telephony over Wireless Links vorgelegt von Diplom-Ingenieur Christian Hoene von der Fakult¨at IV - Elektrotechnik und Informatik der Technischen Universit¨at Berlin zur Erlangung des akademischen Grades Doktor der Ingenieurwissenschaften – Dr.-Ing. – genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Heiß Berichter: Prof. Dr.-Ing. Wolisz Berichter: Prof. Dr.-Ing. Steinmetz Berichter: Prof. Dr.-Ing. Sikora Tag der wissenschaftlichen Aussprache: 16. Dezember 2005 Berlin 2006 D83 c 2005-2006 by Christian Hoene Jahnstr. 22 72144 Dußlingen Germany [email protected] As a small child, you never spoke that clearly, no wonder that you want to improve the speech perceptibility. My mother, after hearing my thesis topic. Abstract This thesis presents algorithms to enhance the efficiency of packetized, interactive speech communication over wireless networks. The results achieved are the following: We present an improved approach to assess the quality of voice transmissions in IP-based communication networks. We combined the ITU E-Model, the ITU PESQ algorithm, and various codec and playout schedulers to analyse VoIP traces. Parts of this algorithm have been included in ITU standards. By using this assessment approach we derived design guidelines for application and data-link protocols. Also, we developed a quality model to parametrise adaptive VoIP applications. Later results received a best-paper award. If highly compressed packetized speech is transported over packet networks, losses of in- dividual packets impair the perceptual quality of the received stream differently, depending on the content and context of the lost packets. We introduce the idea of the Importance of Individual Packets, which is defined by the impact of VoIP packet loss on speech quality. -

Integration of Asterisk IP-PBX with ESP32 Embedded System for Remote Code Execution †
Proceedings Integration of Asterisk IP-PBX with ESP32 Embedded System for Remote Code Execution † Juan Pablo Berrío López 1,* and Yury Montoya Pérez 2 1 Facultad de Ingeniería, Diseño e Innovación (FIDI), Institución Universitaria Politécnico Grancolombiano, 050034 Medellín, Colombia 2 Facultad de Ciencias Básicas e Ingeniería, Corporación Universitaria Remington, 050012 Medellín, Colombia * Correspondence: [email protected]; Tel.: +57-304-439-7353 † Presented at the 2nd XoveTIC Congress, A Coruña, Spain, 5–6 September 2019. Published: 5 August 2019 Abstract: This paper explains the design and construction of a platform that implements the ESP32 embedded system and connects it to a telephone asterisk plant, to exchange data on both sides, commands sent from a telephone to the esp32 and make calls from an order of sending from a digital input of esp32. It is a low-cost device that can be implemented through the use of Wi-Fi, and as a use in the industry, it has a role in analogue communication in buildings, for example. Keywords: sensors; wireless fidelity; internet of things; microcontrollers; ESP32; embedded systems 1. Introduction Internet of Things is a concept based on the connection of electronic devices with each other or through the Internet, which has been generating expectation for years as it is expected to be a great driver of digital transformation in homes and cities, as well as in companies. IP telephony has taken a central role in the information highway so that the network can interconnect each home and each business through a packet switching network [1,2]. In this work, the Asterisk pbx was used based on the Issabel Linux distribution, which allowed to create dial plans to receive calls from the users and through an IVR to make a POST request to the ESP32 platform, which within its code has established methods that for investigation, allowed to move a servo motor and turn on led lights.
