[asterisk-r2] problemas DTMF R2

Tue May 22 13:36:42 CDT 2012

Hola Yuliesky

Cuando ejecutas como root un dahdi_tool ves al E1 sincronizado?

Que distribucion o linux estas utilizando?

Alguna vez vi algo parecido y era que la version de los modulos no correpondia al kernel, y daba error cuando el dahdi trataba de iniciarse, y por supuesto asterisk no muestra los comandos mfcr2, ni siquiera con un help.

Saludos,

Buen día:

Estoy configurando un enlace E1 con CANTV - Venezuela, a continuacion
la informacion de los componentes de software instalados:

OpenR2 version: 1.3.2
DAHDI Version: 2.6.1
Asterisk 10.4.0
Tarjeta:  pci:0000:30:00.0     wct4xxp+     d161:0210 Wildcard TE210P (4th Gen)

Cantv me entrega 1 E1 fraccionado, 1-15 entrantes, 17-31 salientes

A continuación la configuración de los ficheros

Chan_dahdi.conf

cas=17-31:1101

# Global data

loadzone    = ve
defaultzone    = ve

El problema esta que cuando coloco el E1 y ejecuto los siguientes
comandos dentro del CLI de asterisk arroja que los comandos no son
encontrados

mfcr2 show channels

dahdi show channels

Esto se debe a que el modulo chan_dahdi.so no esta cargado, entonces
ejecuto module load chan_dahdi.so y me arroja el siguiente error

Unable to load module chan_dahdi.so
Command 'module load chan_dahdi.so' failed.
