Bueno pos tras cargar mi memoria virtual intento arrancar Openser y me dice que el modulo de mysql.so esta obsoleto con lo cual me quedo como asi :| , pero bueno pienso habra sido problema de la instalación de TLS que tendria que haber añadido el modulo de mysql por realizo otra instalación (sin hacer clean,eso lo voy a a probar ahora),me lo instala pero no me arranca openser me dice listening : Aliases: y de repente la petada del mi_fifo que si lo tengo puesto en el openser.cfg y en openserctrl . alguna idea?? -- ===================================================== Legolas_Bilbao[ID2006][GKR] Dios creo un equipo Perfecto a los demas los lleno de extranjeros http://www.forosindicedonkey.com http://usuarios.lycos.es/ligaforo/ =====================================================

Detectar gateway caido
by Antonio 19 Dec '09

19 Dec '09

hola estos dias tengo un rato libre y estoy "jugueteando" con Kamalio, la verdad que soy nuevo en esto y me estaba preguntando si existe alguna funcion para detectar si un gw esta caido y no ruta la llamada a el. Me refiero a que si por ejemplo tienes dos gw y no ha "cascado" no rute la llamada a el, lo pregunto por si esta echa no intentar jugar con las maquinas virtuales y algo de script o programacion para detectar esto (aunque no me vendria mal para pasar el rato). ¿Y para detectar por ejemplo que si hay dos usuarios ya en ese gw la siguiente llamada la pase al otro gw?.gracias ! saludos !

Sin Audio con llamadas a PSTN con caller detras de NAT, audio correcto entre usuarios detras de NAT con VoIP pura
by rubenrojas - Trc.es 18 Dec '09

Buenos días, ya la semana pasada me ayudaron a lograr que el audio funcionara bien mediante el RTPProxy cuando ambos usuarios se encontraban detrás de una NAT y registrando el Contact con IPs locales y el Received con la IP Publica y el puerto de NAT Lo que vengo a preguntar hoy es la evolución de dicho problema, ahora las llamadas a PSTN no tienen audio cuando el usuario que llama esta detras de una NAT y no puede registrarse con su IP Pública en el Contact. estoy utilizando el modulo dispatcher para realizar roundrobin entre dos asterisk (192.168.1.230 y 192.168.1.231), esto va perfecto cuando la llamada viene desde un telefono SIP con IP Publica y la llamada no tiene audio cuando la llamada viene desde un telefono SIP detras de una NAT que forza a registrar al Contact con la IP Privada. esto se resolvia con llamadas VoIP puras realizando fix_nated_contact() y force_rtp_proxy() en la ruta onreply_route[]. En este caso luego de hacer el dispatch hacia los Asterisk, el asterisk me devuelve la llamada al kamailio cuando la han aceptado pero no puede ubicar al llamante con su IP privada ocasionada por el NAT y tampoco llega al onreply_route[] para realizar el fix_nated_contact() y el force_rtp_proxy() Podrían ayudarme a conseguir ¿porque la llamada con la que me conecta el Asterisk no pasa por el onreply_route[] que utilizan las llamadas VoIP puras? muchas gracias de antemano... aquí coloco mi cfg ************************************************************************************************** # # $Id: kamailio.cfg 5800 2009-04-20 11:01:49Z miconda $ # # Kamailio (OpenSER) SIP Server - basic configuration script # - web: http://www.kamailio.org # - svn: http://openser.svn.sourceforge.net/viewvc/openser/ # # Direct your questions about this file to: <users en lists.kamailio.org> # # Refer to the Core CookBook at http://www.kamailio.org/dokuwiki/doku.php # for an explanation of possible statements, functions and parameters. # # There are comments showing how to enable different features in th econfig # file.
