I looked the following thread but I did't find something to change in my configuration.
Anyone knows what is the posible cause?
I attach the configuration and debug
Thanks

!!! UPDATE !!!
There is an update related to this topic:
The problem was corrected on the Service Provider side ... they corrected some parameters inside their network Infrastructure.
This is the IOS Version:
Version 12.4(17)
flash:c2800nm-advipservicesk9-mz.124-17.bin

Checking different customer configs and Telmex recommendation, and all points to this configuration: (Just change channels used)
controller E1 0/1
framing NO-CRC4
ds0-group 1 timeslots 1-15,17-31 type r2-digital r2-compelled ani
cas-custom 1
country telmex
category 2
answer-signal group-b 1
***********************************************************************
Please give it a try at the following config:
controller E1 1/0
framing NO-CRC4
clock source line
line-termination 75-ohm
ds0-group 0 timeslots 1-8 type r2-digital r2-compelled ani
cas-custom 0
country telmex
seizure-ack-time 30
category 2
answer-signal group-b 1
dnis-digits min 4 max 4
dnis-complete
timer interdigit incoming 1000
groupa-callerid-end
voice-port 1/0:0
cptone mexico
Check the following:
For inbound calls from Telmex to router you can configure
dnis-digits min x max y
timer interdigit incoming 1000
This will reduce the interdigit timer to 1 sec and we will collect between x and y digits from pbx for the dnis.
Have you already made a loopback test?
Let us know
