Implementación de Central Telefónica Asterisk sobre Raspberry incluyendo Tarifación y Seguridad para el Usuario / Implementation of Asterisk (PBX) on Raspberry including Pricing and User Security
Abstract
En este artÃculo se encuentra la descripción de un sistema completo de comunicación donde se saca provecho a todas las particularidades que una central telefónica pueda ofrecer, dirigida especialmente para medianas o pequeñas empresas que busquen el mejor sistema de comunicación por VoIP a un menor costo. Se destacan aspectos como la utilización de software gratuito de telefonÃa disponible, como Asterisk, para la implementación de la central telefónica y un sistema de tarifación con licencia libre llamado Servitux, el cual se utilizó para el control y cobro de cada llamada externa, también se manejó hardware de bajo costo, como es la tarjeta Raspberry Pi, donde se buscó aprovechar las ventajas del sistema operativo dando más seguridad por medio de programación en lenguaje php y html, brindando la posibilidad del cambio de clave para cada una de las diferentes extensiones en la central. Finalmente se realizan pruebas de estrés utilizando el software de licencia libre SIPp, definiendo la capacidad del sistema. También por medio de un análisis MOS queda demostrado que se puede satisfacer las necesidades del cliente en cuanto a la calidad y confiabilidad en el servicio de voz QoE.References
