Estimados, necesito de su ayuda urgente. Estoy instalando un servidor HP ML110 con Elastix, avanza todo bien hasta que conectado la E1. Despues de unas horas, empiezo a escuchar un ruido muy feo en las conversacones y luego recibo el siguiente mensaje desde los logs (/var/log/asterisk/full):

NOTICE[3006] chan_dahdi.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1

Luego de eso, se cuelga la E1, solo reiniciando servidor vuelve a la normalidad. Adjunto configuración de archivos:

system.conf

# If you edit this file and execute /usr/sbin/dahdi_genconf again,

podria ser problema del clock

# Span 1: WCT1/0 "Wildcard TE121 Card 0" (MASTER) HDB3/CCS RED
span=1,0,0,ccs,hdb3

asi lo tienes, el segundo parametro dentro de span es si es clocked local o remote, cambialo a uno
# Span 1: WCT1/0 "Wildcard TE121 Card 0" (MASTER) HDB3/CCS RED
span=1,1,0,ccs,hdb3
