Hola.
Tengo una instalación con FXO Grandstream y Openser con varios teléfonos
IP registrados, y el problema que tengo es que las llamadas que entran a
través del FXO, al transferirlas entre teléfonos IP se cortan. No se
pueden transferir llamadas externas entre teléfonos IP. Sin embargo con
las llamadas internas entre los propios teléfonos IP no hay ningún
problema para transferirlas. Este problema ha surgido a raíz de cambiar
el modo de funcionamiento del FXO para que las llamadas entrantes suenen
directamente en los teléfonos IP. Con la configuración anterior según la
cual cuando entraba la llamada en el FXO era necesario una segunda
marcación para seleccionar la extensión IP, la transferencia de llamadas
funcionaba correctamente.
¿Me puede por favor echar alguien una mano a identificar la causa del
corte en las transferencias? Muchas gracias de antemano.
Adjunto traza ngrep, de una llamada externa entrante a la extensión 43 a
través del canal FXO 9873, y el intento de transferencia de esta llamada
desde la extensión 43 hacia la extensión 42. La traza a partir de
haberse atendido ya la llamada externa en la extensión 42.

¿Algún alma caritativa que me pueda echar una mano...?
Jose Fernandez escribió:
Hola.
Tengo una instalación con FXO Grandstream y Openser con varios teléfonos
IP registrados, y el problema que tengo es que las llamadas que entran a
través del FXO, al transferirlas entre teléfonos IP se cortan. No se
pueden transferir llamadas externas entre teléfonos IP. Sin embargo con
las llamadas internas entre los propios teléfonos IP no hay ningún
problema para transferirlas. Este problema ha surgido a raíz de cambiar
el modo de funcionamiento del FXO para que las llamadas entrantes suenen
directamente en los teléfonos IP. Con la configuración anterior según la
cual cuando entraba la llamada en el FXO era necesario una segunda
marcación para seleccionar la extensión IP, la transferencia de llamadas
funcionaba correctamente.
¿Me puede por favor echar alguien una mano a identificar la causa del
corte en las transferencias? Muchas gracias de antemano.
Adjunto traza ngrep, de una llamada externa entrante a la extensión 43 a
través del canal FXO 9873, y el intento de transferencia de esta llamada
desde la extensión 43 hacia la extensión 42. La traza a partir de
haberse atendido ya la llamada externa en la extensión 42.

¿Algún alma caritativa que me pueda echar una mano...?
Hola Jose, el problema no está bien definido y tampoco es plan de
estudiar un trace SIP tan largo para deducir de qué va todo esto.
Comentas que antes tenías que hacer una "segunda marcación", eso tiene
pinta de que contestaba una especie de centralita y por DTMF marcábais
la extensión final. Eso no explica ni arregla nada, era un escenario
completamente diferente y dejar de usarlo no tiene como consecuencia
lógica que dejen de funcionar las transferencias.
Es decir, olvida el escenario anterior porque no ayuda en nada a
describir el problema actual (antes funcionaba, pues muy bien) e
intenta averiguar un poco más qué está pasando a nivel SIP en tu nuevo
entorno (no vale con pegar toda la traza SIP).
Si consigues acotar un poco más el problema yo estaré muy dispuesto a
echarte una mano.
Saludos.

Muchas gracias por responder Iñaki.
Supongo que con "no está bien definido" te refieres a que he soltado
demasiado rollo para explicar el problema. La intención era dar los
mayores detalles posibles, por lo mismo que he incluido toda la traza
sip. Intento simplificar:
* Escenario: GW FXO, Openser 1.1 y varios teléfonos IP. Llamada
entrante que vía FXO (canal registrado como 9873) suena
directamente en el teléfono IP 43, y una vez atendida,
transferencia de esa llamada al teléfono IP 42.
* Problema: Se corta esa transferencia perdiéndose la comunicación
entre todos los puntos.
* Resumen traza SIP:
Una vez establecida comunicación 43 (192.18.20.13) con 42
(192.168.20.12) para iniciar la transferencia, 43 envía REFER a 9873
(FXO 192.168.10.2:5066). El servidor Openser es la 192.168.20.1:
Se acepta por parte del FXO:

Para el resto resumo todo lo posible la parte final de la traza:
FXO --> Openser: NOTIFY de FXO a 43.
Openser --> 43: NOTIFY de FXO a 43.
FXO --> Openser: INVITE de FXO a 42.
Openser --> FXO: Trying al INVITE de FXO a 42.
Openser --> 42: INVITE de FXO a 42.
43 --> Openser: 200 OK al NOTIFY de FXO a 43.
Openser --> FXO: 200 OK al NOTIFY de FXO a 43.
43 --> Openser: BYE de 43 a FXO.
Openser --> FXO: BYE de 43 a FXO.
Openser --> 42: INVITE de FXO a 42.
Openser --> FXO: BYE de 43 a FXO.
FXO --> Openser: 200 OK al BYE de 43 a FXO.
Openser --> 43: 200 OK al BYE de 43 a FXO
FXO --> Openser: 481 No Such Call de 43 a FXO.
42 --> Openser: 100 Trying al INVITE de FXO a 42.
42 --> Openser: 200 OK al INVITE de FXO a 42.
Openser --> FXO: 200 OK al INVITE de FXO a 42.
42 --> Openser: BYE de 42 a 43.
Openser --> 43: BYE de 42 a 43.
FXO --> Openser: CANCEL de FXO a 42.
Openser --> FXO: "200 ok -- no more pending branches" de FXO a 42.
42 --> Openser: 200 OK al INVITE de FXO a 42.
Openser --> FXO: 200 OK al INVITE de FXO a 42.
FXO --> Openser: ACK de FXO a 42.
Openser --> 42: ACK de FXO a 42.
43 --> Openser: 200 OK al BYE de 42 a 43.
Openser --> 42: 200 OK al BYE de 42 a 43.
FXO --> Openser: ACK de FXO a 42.
Openser --> 42: ACK de FXO a 42.
42 --> Openser: BYE de 42 a FXO.
Openser --> FXO: BYE de 42 a FXO.
FXO --> Openser: 481 No such call de 42 a FXO.
Openser --> 42: 481 No such call de 42 a FXO.
No entiendo muy bien por qué aparece un CANCEL del FXO al 42 después de
recibir el FXO un 200 OK de 42 al INVITE previo, ni el "no such call" al
BYE de la 43 al FXO.
No tengo demasiada experiencia y no tengo claro si la secuencia es
correcta en una transferencia de llamada SIP. ¿La secuencia en una
transferencia correcta sería la misma?

¿Algún alma caritativa que me pueda echar una

Hola Jose, el problema no está bien definido y tampoco es plan de
estudiar un trace SIP tan largo para deducir de qué va todo esto.
Comentas que antes tenías que hacer una "segunda marcación", eso tiene
pinta de que contestaba una especie de centralita y por DTMF marcábais
la extensión final. Eso no explica ni arregla nada, era un escenario
completamente diferente y dejar de usarlo no tiene como consecuencia
lógica que dejen de funcionar las transferencias.
Es decir, olvida el escenario anterior porque no ayuda en nada a
describir el problema actual (antes funcionaba, pues muy bien) e
intenta averiguar un poco más qué está pasando a nivel SIP en tu nuevo
entorno (no vale con pegar toda la traza SIP).
Si consigues acotar un poco más el problema yo estaré muy dispuesto a
echarte una mano.
Saludos.

Supongo que con "no está bien definido" te refieres a que he soltado
demasiado rollo para explicar el problema. La intención era dar los
mayores detalles posibles, por lo mismo que he incluido toda la traza
sip. Intento simplificar:
Hola, realmente adjuntar la traza SIP es perfecto (en mi opinión), lo que
echaba en falta era un poco más de explicación previa, para saber qué buscar
en la traza SIP ;)
Pero ahora ya está más o menos claro.
* Escenario: GW FXO, Openser 1.1 y varios
teléfonos IP. Llamada
entrante que vía FXO (canal registrado como 9873) suena
directamente en el teléfono IP 43, y una vez atendida,
transferencia de esa llamada al teléfono IP 42.
* Problema: Se corta esa transferencia perdiéndose la comunicación
entre todos los puntos.
He notado que hay retransmisiones (INVITE's repetidos que llegan al UAS). Esto
provoca que al aceptarse uno el proxy envíe un CANCEL para cancelar el otro,
el UAS recive dicho CANCEL y cancela la primera llamada (aunque no debería
pues ya fue contestada) y envía un BYE (no debería).
Una pregunta, ¿usas "t_relay" en el script de OpenSer? Tienes que
usar "t_relay" para evitar las retransmisiones, o sea, que si el UAC envía un
INVITE, llega a OpenSer, pasa un poco de tiempo sin recibir respuesta y el
UAC repite el INVITE, entonces OpenSer debe absorver dicho INVITE repetido,
pero para ello debe haber creado una transacción. Al rutar un mensaje
con "t_relay" se crea la transacción, pero también la puedes hacer antes
ejectutando "t_newtran" cuando empiezas a procesar el mensaje.

La secuencia es más o menos correcta, yo creo que el UAS se comporta mal al
recibir 2 INVITE's iguales (retransmisiones) y un CANCEL.
Yo lo que te recomiendo es que te asegures de que OpenSer absorbe las
retransmisiones, es decir, el INVITE puede llegar varias veces a OpenSer,
pero sólo debe salir una vez de OpenSer y absorber las repeticiones.
Compruébalo haciendo más trazas SIP y comparando el "branch" del Via.
Y otra cosa, prueba a sustituir el teléfono 42 por otro modelo o softphone. Si
puedes pon un Twinkle que eso no falla ;)

Gracias de nuevo.
Voy a documentarme un poco sobre el uso de t_relay porque me coge
totalmente de nuevas. Lo único que tengo configurado en el openser.cfg es:
route[1] {
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
if (!t_relay()) {
sl_reply_error();
};
exit;
}
Voy a indagar a ver si me entero de qué va y se me hace la luz... : )
Un saludo.
