Voip IP thelephony bad Calling number interpretation

HI folks,

We are using a CUCM 6.x and h323 gw with BRI interfaces. in last days there is a problem with calling number interpretation on the external phone calls. there are missing last 2 digits on the interpreted number.

I have checked the output of the Caling number in the setup message outgoing from the GW and the phone number is in correct format. But on my display I miss last 2 digits of the phone number.

Users are using CIPC

Can be the problem with the numbers in the CUCM or on the provider side?

Not every number is affected with this issue.

I have used the debug ISDN q931 to check the outgoing traffic.

 

Thanks in advance

How many do you route calls

How many do you route calls in CUCM? Do you use the Local Route Groups, Globalized Dialing or traditional Route Patterns?

Hi Josh,meanwhile we have

Hi Josh,

meanwhile we have solved the issue, we have used traditional route patterns..

the problem was in the sending wrong type and plan settings to ISDN provider (External phone number mask didnt matched the translation pattern on the GW and therefore it was sent like unknown/unknown and correct value should be Plan : ISDN and Type: National)

thank you very much for a piece of your time  and for replying on this topic.
