Problema Unable to create channel of type 'DAHDI' (cause 34 - Circuit/channel congest

[julianarmando]

Hola, como es un error diferente, abro este hilo, aunque va relacionado con el anterior http://asteriskmx.com/foros/showthre...hlight=sangoma

He podido dar solución a ese error, ahora, sucede lo siguiente cuando intento hacer una llamada..

-- Executing [92682486@grupo1:1] Dial("SIP/111111-00000084", "DAHDI/g0/2682486") in new stack

¿ Podrían colaborarme?

Muchas gracias!

Según eso, no tienes canales o no tienes los grupos declarados.

¿Qué tienes en tu chan_dahdi.conf y en tu dahdi-channels.conf?

[julianarmando]

En /etc/asterisk/chan_dahdi.conf tengo:

[Christian Cabrera]

Ese parece ser el problema: no tienes ninguna configuración válida en tus canales (tienes la misma configuración equivocada para ISDN que tenías antes en tu system.conf).


Cambia el bloque en el chan_dahdi.conf que dice esto:

;Sangoma A101 port 1 [slot:4 bus:12 span:1] <wanpipe1>
;switchtype=national
context=from-pstn
group=1
;echocancel=no
signalling=pri_cpe
channel =>1-15
channel =>17-31

Por esto:

signalling=mfcr2
mfcr2_variant=ar
mfcr2_get_ani_first=no
mfcr2_max_ani=10
mfcr2_max_dnis=4
mfcr2_category=national_subscriber
mfcr2_mfback_timeout=-1
mfcr2_metering_pulse_timeout=-1
mfcr2_forced_relaase=no
; this is for debugging purposes
mfcr2_logdir=log
mfcr2_logging=all
group=1
channel =>1-15,17-31

Nunca he configurado para la variante argentina, pero al menos de entrada no debe ser tan diferente que la mexicana, al menos con que especifiques ar debe ser un buen primer paso.

Reinicia Asterisk e intenta de nuevo llamar a traves de g1.

Hola,

Al intentar recargar el Dahdi dentro del asterisk con esta configuración me aparecen los siguientes errores:

[Jan 21 16:41:52] ERROR[17561]: chan_dahdi.c:12818 process_dahdi: Unknown signalling method 'mfcr2'

[Christian Cabrera]

No tienes la libreria OpenR2 instalada, empezando por allí. Hay muchos tutoriales en linea que puedes seguir para esta configuración: https://www.google.com.mx/search?q=c...hrome&ie=UTF-8

Hola,

Muchas gracias por la información, me he demorado un poco porque he tenido que re compilar casi todo lo que tenia ya instalado, he aplicado la configuración que me recomendaste y esto es lo que sucede ahora cuando intento realizar la llamada (Aun no puedo sacar llamadas)...

Hola, buen dia,

He realizado la configuración para recibir llamadas y las he logrado recibir de manera correcta, pero sigo teniendo el problema con la salida de llamadas!
