How to check DID issue on CCM

Hi Pros,

I am facing a troublesome issue at CU place. I have CCM 4.1.3 & Cisco 3845 Router with 2 PRI Lines connected. These lines have DIDs 56789xxx & 55412xxx on both PRIs. So when calls come in only 3 digits are forwarded to router & to CCM. Inward dialing is fine.

I have configured separate partitions, css & route-patterns for 56789xxx phones & 55412xxx phones respectively as they are using same gateway router. Under each route pattern I have mentioned transform mask also respectively. Partition MUM uses transform mask 56789xxx & Partition MUM1 uses 55412xxx.

My problem is phones using route-pattern in MUM1 partition whose transform mask is 55412xxx show on PSTN Caller ID phones as 56789100 only (the pilot number).

I checked on gateway router, the output of show isdn history shows calling number as 55412750. The provider says its not his issue & he is receiving 56789100 from my PRI.

I wonder what could be the problem here. Are there any more commands I could use to resolve this or to check in realtime what digits are being forwarded by my Router?

Regards,

Pratik

Re: How to check DID issue on CCM

debug isdn q931 will tell you right away what number is leaving your gateway.

Although you might be sending the correct transformed DID, if the call is not pegged properly then it might not get into the translation tables at your telco provider's switch. FOr instance, one of my telco providers was sending my pilot number despite me sending the DID number. Turned out that I was setting my call type to unknown. Once I switched it to national, everything worked fine.

Hi Mark,

Thanks for replying. By call type do you mean the isdn switchtype?

I will try that.

Re: How to check DID issue on CCM

have you done a debug isdn q931 on the voicegateway?

this way you proof the CLI

Re: How to check DID issue on CCM

Hi,

Below is the output of the debug isdn q931. It shows that calling number is 65412750 (which is proper) & called number. When I receive this call, caller ID on my number (9892000111) shows 66789100!

I feel it is provider issue, any more verifications from my side required?

Re: How to check DID issue on CCM

Hi all,

Issue got resolved after changing transform mask in route pattern. It was provider issue. DIDs got changed to 67412xxx.

Thanks all for your help.
