[Kamailio-Users-ES] Asterisk Virtualizado - Sirve Kamailio?
by sadzas 15 Jul '09

15 Jul '09

Hola a todos... Supongan el siguiente escenario (que es en realidad lo que tengo funcionando)... Tengo 3 asterisk virtualizados. Un telefono en cada * virtualizado. El tema es que cada telefono apunta a una IP diferente. Esto es: Asterisk-1 : 192.168.2.1 Asterisk-2 : 192.168.2.2 Asterisk-3 : 192.168.2.3 Cada * tiene diferentes features, como voicemail, meetme, etc etc. Me interesa unificar esto, para que cada telefono apunte a sola una IP. Y luego de acuerdo al interno, lo pueda desviar hacia el * indicado. Todo lo que quiero hacer es un bypassing. Siempre sabiendo que las IPs de los telefonos que se van a registrar son dinamicas y cambian constantemente. Se puede utilizar OpenSer para esto? El problema que le encuentro es que con OpenSer tendria que compartir la BD con Asterisk, o ir a buscar los datos ahi, pero no me imagino como hacer con 3 BD diferentes. mas aun, si asi fuera, me queda la eterna duda de como hacer que la llamada vuelva al telefono desde el Asterisk pasando por OpenSer. Para graficarlo un poco: Asterisk-1 \ Asterisk-2 - IP ------> Telefonos de diferentes * Asterisk-3 / La verdad es que no me imagino con que hacer esto... les agradeceria toda ayuda posible... gracias a todos! -- View this message in context: http://www.nabble.com/Asterisk-Virtualizado---Sirve-Kamailio--tp24185223p24… Sent from the OpenSER Users - ES mailing list archive at Nabble.com.

Gracias por la pronta respuesta, asi da gusto unirse a una comunidad, he colocado varios xlog en onreply_route[1] y lo he dejado asi: onreply_route[1] { xdbg("incoming reply\n"); xlog("L_INFO", "*** onreply_route antes de forzar rtpproxy ***"); if ((isflagset(5) || isbflagset(6)) && status=~"(183)|(2[0-9][0-9])") { xlog("L_INFO", "*** rtpproxy forzado en onreply_route ***"); force_rtp_proxy(); } if (isbflagset(6)) { xlog("L_INFO", "*** fix_nated_contact en onreply_route ***"); fix_nated_contact(); } } haciendo un tail -f /var/log/syslog veo lo siguiente: Jun 25 13:39:51 kamailio /usr/local/sbin/kamailio[22088]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:51 kamailio /usr/local/sbin/kamailio[22087]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22088]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22088]: *** rtpproxy forzado en onreply_route *** Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22088]: ACC: transaction answered: timestamp=1245929995;method=INVITE;from_tag=5c805948a0455e5b;to_tag=c0a80101-3569b;call_id=d1b81cbb5fbb9e6e(a)192.168.254.110;code=200;reason=OK;src_user=20000004;src_domain=212.4.107.250;dst_ouser=20000000;dst_user=20000000;dst_domain=192.168.254.101 Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22089]: ACC: request acknowledged: timestamp=1245929995;method=ACK;from_tag=5c805948a0455e5b;to_tag=c0a80101-3569b;call_id=d1b81cbb5fbb9e6e(a)192.168.254.110;code=200;reason=OK;src_user=20000004;src_domain=212.4.107.250;dst_ouser=20000000;dst_user=20000000;dst_domain=192.168.254.101 Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22088]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:55 kamailio /usr/local/sbin/kamailio[22088]: *** rtpproxy forzado en onreply_route *** Jun 25 13:39:56 kamailio /usr/local/sbin/kamailio[22089]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:56 kamailio /usr/local/sbin/kamailio[22089]: *** rtpproxy forzado en onreply_route *** Jun 25 13:39:58 kamailio /usr/local/sbin/kamailio[22087]: *** onreply_route antes de forzar rtpproxy *** Jun 25 13:39:58 kamailio /usr/local/sbin/kamailio[22087]: *** rtpproxy forzado en onreply_route *** por lo que veo si hace el force_rtp_proxy() pero no hace nunca el fix_nated_contact() en onreply_route ----- Mensaje original ----- De: "Iñaki Baz Castillo" <ibc(a)aliax.net> Para: users-es(a)lists.kamailio.org Enviados: Jueves, 25 de Junio de 2009 13:25:18 GMT +01:00 Amsterdam / Berlín / Berna / Roma / Estocolmo / Viena Asunto: Re: [SR-Users-ES] No Audio con clientes detras de una NAT, el audio funciona con clientes que usan IPs publicas (Estoy utilizando rtpproxy) El Jueves, 25 de Junio de 2009, Iñaki Baz Castillo escribió: > El Jueves, 25 de Junio de 2009, rubenrojas - Trc.es escribió: > > # Caller NAT detection route > > /* uncomment the whole following route for enabling Caller NAT Detection > > */ route[4]{ > > force_rport(); > > if (nat_uac_test("19")) { > > if (method=="REGISTER") { > > fix_nated_register(); > > } else { > > fix_nated_contact(); > > } > > setflag(5); > > } > > return; > > } > > Lo anterior NO se está ejecutando.

Perdona, lo de arriba sí se está ejecutando (el Contact del INVITE cambia). Lo que no cambia es el de la respuesta, o sea, no se ejecuta esto: onreply_route[1] { xdbg("incoming reply\n"); if ((isflagset(5) || isbflagset(6)) && status=~"(183)|(2[0-9][0-9])") { force_rtp_proxy(); } if (isbflagset(6)) { fix_nated_contact(); } } Lo que no sé es porqué no se ejecuta puesto que tienes puesto en t_onreply("1") en route[1]. Eso tendrás que descubrirlo a base de poner "xlog" para ver si se están eejcutando los bloques o no. Nadie garantiza que el config file que viene por defecto sea 100% correcto. -- Iñaki Baz Castillo <ibc(a)aliax.net> _______________________________________________ SR-Users-ES mailing list SR-Users-ES(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users-es _________________________________________________________________ Este mensaje ha sido escaneado en busca de virus por MailScanner.

Gracias Iñaki ya lo he solucionado (temporalmente), de hecho hay dos bugs en la configuracion por defecto el 1ro en el failure_route[1] la linea if (is_method("INVITE") viene sin la segunda comilla, osea originalmente es asi: if (is_method("INVITE) al activar el nat kamailio no inicia hasta que no se le coloque la comilla que faltaba el 2do (el que nos trajo hasta aqui): en onreply_route[1] no llega el flag 6 activo de momento he colocado el fix_nated_contact(); en el mismo bloque que el force_rtp_proxy() y va perfecto si veis donde podra estar la perdida de este flag, por favor colocarlo aqui en la lista para dejar la configuracion por defecto del kamailio lo mejor posible muchas gracias ----- Mensaje original ----- De: "Iñaki Baz Castillo" <ibc(a)aliax.net> Para: users-es(a)lists.kamailio.org Enviados: Jueves, 25 de Junio de 2009 13:44:55 GMT +01:00 Amsterdam / Berlín / Berna / Roma / Estocolmo / Viena Asunto: Re: [SR-Users-ES] No Audio con clientes detras de una NAT, el audio funciona con clientes que usan IPs publicas (Estoy utilizando rtpproxy) El Jueves, 25 de Junio de 2009, rubenrojas - Trc.es escribió: > por lo que veo si hace el force_rtp_proxy() pero no hace nunca el > fix_nated_contact() en onreply_route Sí, como dije el problema no es el SDP de las respuestas (la IP y puerto se ven claramente modificados por el proxy) sino en el Contact. Pues te toca investigar lo mismo pero con el fix_nated_contact (añade xlogs a porrillo). Tal vez has descubierto un bug en el config por defecto de Kamailio. -- Iñaki Baz Castillo <ibc(a)aliax.net> _______________________________________________ SR-Users-ES mailing list SR-Users-ES(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users-es _________________________________________________________________ Este mensaje ha sido escaneado en busca de virus por MailScanner.

No Audio con clientes detras de una NAT, el audio funciona con clientes que usan IPs publicas (Estoy utilizando rtpproxy)
by rubenrojas - Trc.es 25 Jun '09

Hola, este es mi primer post en esta lista, Tengo instalado el kamailio 1.5.1 y estoy utilizando un kamailio.cfg utilizando el que trae por defecto, luego he modificado el cfg para activar mysql, domain, presence, nathelper y authentication con md5, todo funciona como se supone que deberia, los clientes pueden registrarse, enviar mensajes de texto y hablar entre ellos. El unico problema es el audio cuando dos clientes estan detras de una NAT, los telefonos pueden realizar la llamada y suena el ring, pero cuando se descuelga no hay audio en ninguna direccion. cuendo los telefonos tienen una IP publica todo funciona bien, tambien funciona cuando utilizo un Linksys PAP2T con las opciones "Insert VIA received", "Insert VIA rport", "Handle VIA received", "Handle VIA rport" y "NAT mapping enable" encendidas, con el softphone de Qutecom stambien funciona. Este problema me esta sucediendo con los telefonos fisicos Thomson phones (model ST 2022) y GrandStream Budge Tone 200, este problema ocurre sin importar que opciones le coloque para el tipo de nateo dentro de los telefonos, Incluso he utilizado stun con stunserver.org o con el servidor de stun de ekiga, los telefonos se registran y pueden hacer y recibir llamadas, pero no hay audio cuando atiendes la llamada. Con kamctl ul show, puedes ver que han registrado el Contact con su IP local y el Received con la IP publica y los puertos para el NAT La unica diferencia con los Linksys que si funcionan es que los Linksys registran el Contact con la IP publica. Aqui se puede ver dos telefonos con NAT en el proxy Domain:: location table=512 records=2 max_slot=1 AOR:: 20000004(a)212.4.107.250 Contact:: sip:20000004@192.168.254.110:5060;transport=udp;user=phone Q= Expires:: 1150 Callid:: 72ed03f6d2f390f9(a)192.168.254.110 Cseq:: 10003 User-agent:: Grandstream BT200 1.1.6.27 Received:: sip:212.4.97.115:35379 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 7807 AOR:: 20000000(a)212.4.107.250 Contact:: sip:20000000@192.168.254.101:5060;user=phone Q= Expires:: 2945 Callid:: 17fe-c0a80101-5-1(a)192.168.254.101 Cseq:: 6 User-agent:: THOMSON ST2022 hw2 fw3.56 00-18-F6-B5-7E-06 Received:: sip:212.4.97.115:55128 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 4294967295 Estoy utilizando rtpproxy y no hay ningun error en el log que indique que el rtpproxy no esta funcionando, de hecho haciendo un SIP trace muestra al rtpproxy seteando puertos para el audio.

Hola a todos. Con el modulo Textops, puedo cambiar partes de la senalizacion, reemplazando, agregando, en resumen, editando. Me interesa crear de 0 un INVITE. Por ejemplo: Hago esto: if (is_method("INVITE") && $rU =~ "loquesea"){ force_rtp_proxy(); t_on_failure("1"); route(x); }; route[x] { log(1, "Reenvia creando un INVITE \n"); --->CREAR EL INVITE<----- t_relay("udp:adondequiero:5060"); t_on_reply("1"); exit; } Y poner en el Invite a modo de variables, los valores que quiero, por ejemplo: numA= loquesea numB= adondequiero "SIP to address: sip:numA@numB" No se si me explique bien... pretendo crear un INVITE desde 0 utilizando una especie de plantilla de senalizacion donde le aregaria los valores de acuerdo a mi criterio... tal vez se podria levantar esta plantilla desde un TXT, o algo parecido... es esto posible? Muchas gracias. -- View this message in context: http://www.nabble.com/Consulta-Basica-acerca-de-kamailio-tp24147809p2414780… Sent from the OpenSER Users - ES mailing list archive at Nabble.com.
