Hola buen dia,

Ojalá puedan ayudarme, tengo el siguiente problema.

Tengo configurada un enlace E1 de TELMEX para trabajar con este conmutador. El problema es que las llamadas de cuelgan después de aproximandamente 2 minutos, esto sucede siempre.

Lo errores del log son (abajo pongo el log completo):

dahdi_hangup: disconnecting MFC/R2 call on chan X
dahdi_ast_cause_to_r2_cause: ast cause 16 resulted in openr2 cause 6/Normal Clearing
chan_dahdi.c:8215 handle_alarms: Detected alarm on channel X: Yellow Alarm
handle_clear_alarms: Alarm cleared on channel X

Esta es mi configuracioón:


[root@asterisk-gdf ~]# vim /etc/dahdi/system.conf

# Autogenerated by /usr/sbin/dahdi_genconf on Fri Jun 21 16:29:54 2013
