Abstract

Un servidor SIP en una infraestructura basada en IP que soporta telefonos inalambricos determina si, con base en la direccion destino en una solicitud de llamada, la llamada es una llamada de intrasistema o una llamada de intersitema. Para llamadas de intrasistema el servidor SIP direcciona paquetes de VOIP directamente entre los dispositivos de origen y destino. Sin embargo, para llamadas de intersistema, y en particular llamadas encriptadas, en lugar de direccional los paquetes de VOIP por la Internet Publica, el servidor SIP instancia una llamada en conmutacion de circuitos utilizando un banco de modems local conectado a la PSTN. De esta manera, se obtiene la calidad de garantia de servicio y se reduce la latencia.
