If you move circuit to another router and it works, then its hard to blame the 
carrier!

CAS stinks.

Ahh, missed the part about CAS, sorry.

So is the provider doing something on their side with the MAC of the E1 on your 
side? If the provider is sending 3 digits (regardless if it works on the other 
router) then it should be their issue.

You have the plan and type set according to what the provider expects?

Are you getting 3 digits for the calling or called party?

CAS no q931



Debug shows on bad router we receive 3 digits from provider, move circuit to 
another router we receive 4 digits from provider.

So on router B, do the following and then place an inbound call from a known 
number:

hostname# conf t
hostname (config)# logging console
hostname (config)# exit
hostname# term mon
hostname# debug isdn q931

What do you see for "Calling Party Number i =", "Plan:" and "Type:"? The "plan" 
and "type" fields should be located below the "calling party  number" field. 
Once you've determined that you really are receiving 4 digits from the telco on 
that circuit the next step is to figure out what in the router config is 
stripping the digit. If you find that you are not receiving 4 digits from the 
telco, you can either work with the telco to fix it on the PRI or if the 
missing digit is a constant, you can add it with an inbound voice translation 
rule.

Look at your inbound dial peers; do you have any voice translation rules that 
are doing any digit stripping? Are the inbound voice translations using 
different regex than on the router that is working and if so, what is different?

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.
