serie de protocolos para la señalización y control de la llamada. El desarrollo de medios capaces de manejar comunicaciones de voz, video y datos de manera eficiente, ocasionará en el futuro cambio en precios, operación y estructura de negocios, modificando la naturaleza de la economía en el mercado de las telecomunicaciones. Estos sistemas deben contar con una infraestructura de conmutación y de transporte de datos para lograr un servicio flexible de control de elementos. La plataforma telefónica código abierto Asterisk, está diseñada para interactuar de forma consistente con el software y hardware telefónico existente, logrando la interconexión entre los diferentes protocolos de señalización, de una forma transparente para el usuario final. En este trabajo se proponen algunos procedimientos de diseño e implementación de pasarelas con líneas troncales de acceso a la Red Telefónica Pública Conmutada (PSTN), y su configuración para interoperar entre los distintos estándares de señalización de llamada.</span></em></p>
