No tengo audio en las llamadas que hago.

[anonymous]

Muchas veces cuando realizo llamadas a numeros externos no me da tono de llamada, pero a la persona que llamo si le suena el telefono, cuando descuelga, no olle nada ni yo tampoco.

este es el unico mensaje de error que me da en el registro cuando esto sucede:

21:44:18.230 [MS105000] C:39.2: No RTP packets were received:remoteAddr=193.22.119.2:60166,extAddr=80.33.15.54:9024,localAddr=80.33.15.54:9024

agradeceria cualquier tipo de ayuda.

Muchas Gracias.

¿Estás haciendo llamadas utilizando un Gateway a la PSTN? Si es así, probablemente la configuración de los tonos sea el problema, ya que el gateway utiliza los tonos para determinar cuando la llamada es atendida. Si eso está mal, el gateway no pasa la aceptación de la llamada a la 3CX y no vas a tener audio, aunque sí va a sonar el teléfono remoto.

 

[anonymous]

el operador de telefonia por el cual se realiza la llamada es IP, esta configurado en la centralita 3cx, despues el router, estan abiertos y redirigidos los puertos 5060, 5062, 9000-9015 a la centralita y los telefonos que utilizamos son Linksys SPA941

¿La 3CX pasa correctamente el test del firewall? ¿Sabés qué tipo de NAT tenés en el acceso a internet?

Por favor, poné los niveles de log en "verbose" para que queden anotados los detalles de la mensajería SIP en el estado del servidor. Eso requiere un reinicio de los servicios de la 3CX. Luego intentá hacer una llamada que falle y posteá los logs. Así quizá podamos ver por qué el audio no llega...

Bueno aqui lo tienes, espero que sirva de algo.

[edossantos]

Todo parece correcto en los logs, lo único que encuentro que podría estar causando el problema es el codec utilizado. En los logs se observa que en ambas llamadas se utiliza transcoding. Eso significa que el servidor de tu proveedor utiliza un codec, e internamente necesitás utilizar otro. Si no logran ponerse de acuerdo con los codecs podrías tener el problema que mencionás.

¿Esto te pasa solo con algunas llamadas? Si es así, ¿podés postear los logs de una que si funcione, como para ver si en ese caso no hay transcoding?

 

[anonymous]

la ultima llamada si conecto correctamente, pero la anterior NO, te envio las dos para que compares.

Gracias de nuevo por tu ayuda.

No veo mayores diferencias entre la llamada que funcionó y la que no. En ambas hay transcoding. Lo que no puedo observar con los logs actuales es el detalle de la negociación SDP. Ahí es donde se informan los puertos a utilizar, codecs, etc. Sería ideal tener eso para poder hacer un diagnóstico.

Para obtener eso necesitaría que hagas un trace en el servidor donde está la 3CX, con Ethereal / Wireshark sobre la placa de red utilizada para las llamadas. ¿Podés hacer eso para una llamada exitosa y una que falle?

 

[anonymous]

pero entonces por que? en la que ha dado en el error de audio aparece esta linea y en la que a funcionado NO:


16:48:53.406 [MS105000] C:31.2: No RTP packets were received:remoteAddr=193.22.119.2:53074,extAddr=80.33.15.54:9016,localAddr=80.33.15.54:9016

 

[edossantos]

Justamente eso te indica que la 3CX no recibió audio para esa llamada. Para determinar por qué en una llamada recibió audio y en otra no, necesitamos ver el detalle de la negociación SDP. Ahí se ven los puertos y direcciones IP que se intentan utilizar para el audio, y también los codecs propuestos. Lo que quiero ver es si hay codecs no soportados y si los puertos y direcciones IP son correctas. Eso nos va a dar una pauta de hacia donde seguir analizando el problema.

 

[anonymous]

como hago para sacar el registro que necesitas?

 

[edossantos]

Tenés que instalarte el WireShark (http://www.wireshark.org/) en el server donde esta la 3CX, y ponerlo a sniffear la placa de red que utiliza la 3CX para estas comunicaciones.
Luego de una llamada exitosa y una fallida, guardar los archivos de trace y subirlos al foro.
