[cisco-voip] E1 CAS card in Mexico not getting enough digits

Sun Nov 16 03:18:22 EST 2014

I have a problem with a E1 CAS site in Mexico.  I have two routers. Router B is problem.

In router A I see 4 digits come in on DTMF.
In router B I see 3 digits come in on DTMF. We are missing 1 digit.

I swap the circuit and works fine in router A.  Same IOS both routers.

Controller e1 0/0/0
   Framing NO-CRC4
   dso-group 0 timeslots 1-10 type r2-digital dtmf dnis
   cas-custom 0
   Country telmex
   Seizure-ackt-time 2
