ISDN error message

Hi Guys,

I am experiencing an issue with incoming calls on certain numbers within a range of ddi`s. The debug isdn q931 is returning the following:

I have tried adjusting the ISDN timer but this has not made any difference. Does anyone know why this would affect only certain numbers in a range and what can be done to fix this, thanks.

Exact IOS used ?

Hi,

c2800nm-spservicesk9-mz.124-20.T.bin

Can you use a mainline like 12.4(3j) - much less buggier.

Also check what is going on with these DIDs what the final destination is doing.

Hi Bevil,

Unless i can definately prove it is an IOS issue it would be a bit difficult to change the IOS.

When the call comes in i have a translation rule which is translating this number into 0201010 which is a mobile voice access number.

I then have a pots dial peer and a voip dial peer to match this newly translated number but it is not even hitting my pots dial peer, config is as follows :

dial-peer voice 0201010 pots

description Mobile Voice Access

service ccm

incoming called-number 0201010

no digit-strip

dial-peer voice 124 voip

description Mobile Voice Access Calls

preference 1

destination-pattern 0201010

progress_ind setup enable 3

session target ipv4:10.10.10.10

dtmf-relay h245-alphanumeric

no vad

When dialling this number in particular i get a message from the carrier something about the call not being completed its in Tokyo.

If i ring another number in the same range it goes through perfectly fine.

I don't have to prove anything, the abnormality is evident.

Either "service ccm" does something wrong, or router becomes confused so telco disconnects.

Hi,

Sorry i think you misunderstood what i was saying. I am not asking you to prove something i just mean my client would want me to be sure it is the IOS before letting me change it. I do agree with you tho so sorry if it sounded wrong.

I will try remove the config altogether and start again in case something has been missed.

Thanks for taking a look i appreciate it.

This message resolved my problem!!

I've been trying to resolve the same error for more than 5 days, and it's not a problem of configuration, only IOS.

The 12.4T IOS drops the call because of facility information that comes from the PBX, but the mainline IOS doesn't.

Thanks!!
