[asterisk-r2] Protocol error. Reason = Invalid CAS

Fri Nov 9 09:31:03 CST 2012

Intentar con:
mfcr2_forced_release=yes

Parece que la 1era. situacion esporadica del tracer aparece cuando la Central no esta aun procesando la señal Clear_forward y envia hacia atras la señal de Forced-release. Esto indicaria una situacion de liberación casi simultanea de los 2 usuarios.

Saludos Alberto

Por lo que se observa en el tracer estaria cambiando internamente de 00(forced release) a 11 (señal clearback) y lo esta procesando como señal clear-back en lugar de forced-release.

Habria que investigar si contempla la señal de forced-release.

Saludos Alberto

    Buenos dias.

    Disculpen la demora, les comento que sigo con el mismo problema.

    La llamadas se establecen perfectamente y NO SE CORTAN. El error lo
    veo aleatoriamente en dos escenarios diferentes:

    a) La llamada finaliza con: 

    .......

    Hice las siguientes pruebas:

    - Probé con los siguientes parámetros en chan_dahdi como me comentó
    Ivan Paes José:

    mfcr2_metering_pulse_timeout=500  ó  

    timer.cas_persistance_check=100

    Siguió igual.

    - Instalé irqbalance y veo en /proc/interrupts que se están
    balanceando en dos CPU.

    La placa esta compartiendo IRQ con otros dispositivos.

    De que manera puedo asignar un único IRQ para la placa?

    El dahdi_test me sigue dando bien: Average: 99.998258%

    Que otra cosa puedo probar?

    En este momento estoy esperando respuesta de telefónica para que
    hagamos algunas pruebas.

    Muchas Gracias,

    Diego
