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/ =====================================================

Redirección en 486 o 408
by Pepe 28 Mar '12

28 Mar '12

Hola a tod@s, llevo un tiempo intentando activar la redirección en Kamailio cuando el destinatario tiene activadas dichas redirecciones "callbusy". Este es el último código que tengo en pruebas y no funciona. La redirección directa funciona sin problemas, pero esta no. Al parecer entra dentro de la ruta, detecta el 486 pero no vuelve a llamar a la uri de la redirección. failure_route[FAIL_ONE] { xlog("L_INFO", "entering failure_route for reply code $T_reply_code\n"); if (is_method("INVITE") && (isbflagset(FLB_NATB) || isflagset(FLT_NATS))) { unforce_rtp_proxy(); } if (t_is_canceled()) { exit; } if (t_check_status("486|408")) { xlog("L_NOTICE", "r[FAIL] / &ru TimeOut or Busy\n"); if(avp_db_load("$ru","$avp(s:callbusy)")) { xlog("L_NOTICE", "Callbusy activado!\n"); avp_pushto ("$ru","$avp(s:callbusy)"); xlog("L_NOTICE","$ru\n"); append_branch(); route(BUSY); } } } route[BUSY] { route(NAT); route(RELAY); } Este es el error que puedo ver 3(14163) NOTICE: <script>: KAM-INFO: r[ALIAS] - Checking ALIAS -> 171 3(14163) NOTICE: <script>: ALIAS FOUND: sip:171@xxx.net;user=phone -> xxxx.xxx(a)xxx.net 3(14163) INFO: <script>: RTPPROXY -> M=INVITE RURI=sip:xxxx.xxx@XX.XX.36.116:1548 F=sip:xxx@xxx.net T=sip:171@xxx.net;user=phone IP=XX.XX.32.48 ID=1291401699@XX_XX_32_48 3(14163) ERROR: nathelper [nhelpr_funcs.c:341]: failed to parse Contact URI [] 4(14164) INFO: <script>: entering failure_route for reply code 302 1(14161) INFO: <core> [forward.c:774]: broken reply to forward - no 2nd via 2(14162) INFO: <core> [forward.c:774]: broken reply to forward - no 2nd via Cualquier ayuda será bienvenida Gracias de antemano Saludos Pepe

Problema con NAT y RTPPROXY
by David Candamil Santos 26 Mar '12

26 Mar '12

Hola, estoy utilizando kamailio 3.2.0 (x86_64/linux) y desde hace unos días estoy intentando comunicar un softphone desde el interior de una red con NAT con el exterior. La configuración es la siguiente: Softphone (192.168.0.5) <--> Kamailio (192.168.0.3) <--> Router (192.168.0.1) <--> Softphone sobre smartphone Todos los puertos del router están redireccionados a 192.168.0.3 Tengo instalado rtpproxy 1.2.1-1 con la siguiente configuración: --------------------------/etc/defaults/rtpproxy-------------------------------- # The control socket. #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" # To listen on an UDP socket, uncomment this line: CONTROL_SOCK=udp:127.0.0.1:22222 # Additional options that are passed to the daemon. EXTRA_OPTS="-l candamil.dyndns.org" ---------------------------------------------------------------------------------------- y el funcionamiento es correcto. Este es el mensaje de salida del log de kamailio: ---------------------------------------------------------------------------------------------- Nov 12 20:09:13 condor kamailio[7001]: INFO: rtpproxy [rtpproxy.c:1415]: rtp proxy <udp:127.0.0.1:22222> found, support for it enabled ----------------------------------------------------------------------------------------------- Tanto el softphone del interior de la red como el del exterior son linphone. La configuración del del interior de la red es la siguiente: SIP identity: sip:1001@192.168.0.3 SIP proxy: sip:192.168.0.3 Indico conexión directa a internet. En la del externo especifico como proxy y domain "candamil.dyndns.org", que es la dirección DNS que apunta a la IP de mi router. En este caso, los síntomas son los siguientes: La autentificación de ambos, tanto externo como interno, es correcta. Al realizar una llamada en cualquiera de los dos sentidos, el softphone suena y la llamada se contesta y cuelga correctamente, pero no se transmite la señal de voz. En el log figura el siguiente mensaje: ---------------------------------------------------------------------------------------------- Nov 12 20:23:14 condor kamailio[6991]: ERROR: rtpproxy [rtpproxy.c:2260]: incorrect port 0 in reply from rtp proxy ---------------------------------------------------------------------------------------------- Ocurre lo mismo si en el interno indico que está tras NAT, con la ip del router, y que está tras NAT con un servidor STUN (stunserver.org) En los 3 casos, en el softphone externo, figura una llamada de 1001(a)192.168.0.3, mientras que en el interno, figura una llamada de 1002(a)candamil.dyndns.org. Si cambio en el softphone interno el proxy a sip:candamil.dyndns.org, todo se vuelve a repetir. Si lo que hago es cambiar la SIP identity a sip:1001@candamil.dyndns.org, al realizar una llamada desde interno a externo, el interno no llega a percatarse de que se respondió a la llamada, y aparece el siguiente error en el log: ---------------------------------------------------------------------------------------------------------- Nov 12 20:53:00 condor kamailio[7306]: ERROR: <core> [parser/parse_via.c:2600]: ERROR: parse_via: invalid port number <5060ranch=z9hG4bKc 50f.b4825246.0> Nov 12 20:53:00 condor kamailio[7306]: ERROR: <core> [parser/parse_via.c:2629]: ERROR: parse_via on: <SIP/2.0/UDP 192.168.0.3:5060ranch=z 9hG4bKc50f.b4825246.0;received=87.223.138.84#015#012Via: SIP/2.0/UDP 87.223.138.84:5060;rport=5060;branch=z9hG4bK1021772993#015#012From: <sip:1001@candamil.dyndns.org>;tag=783852345#015#012To: < sip:1002@candamil.dyndns.org>#015#012Call-ID: 1644787160#015#012CSeq: 21 INVITE# 015#012User-Agent: Linphone/3.4.0 (eXosip2/unknown)#015#012Content-Length: 0#015#012#015#012> ------------------------------------------------------------------------------------------------------------ Por el contrario, haciendo una llamada desde el externo al interno, ocurre lo mismo que antes.

Hola, mejor de momento mantenemos el hilo en la lista. Más info abajo: El día 23 de marzo de 2012 16:41, magnusadilsom(a)gmail.com <magnusadilsom(a)gmail.com> escribió: > # ----------------------------------------------------------------- > # Handle Handle NAT > # ----------------------------------------------------------------- > > route[4]{ > > force_rport(); > if (nat_uac_test("19")) { > xlog("L_INFO", "NAT detected1"); > if (method=="REGISTER") { > fix_nated_register(); > } else { > fix_nated_contact(); > fix_nated_sdp("1"); > xlog("L_INFO", "NAT detected2"); > }; > setflag(5); > return; > }; No sólo hay que "corregir" el Contact en el INVITE sino que también en las respuestas 180/183/200 que tengan SDP (on_reply_route y tal). Y lo mismo a la hora de aplicar rtpproxy. -- Iñaki Baz Castillo <ibc(a)aliax.net>
