Caller-ID problems on Cisco Voice Gatway Router

I am using a Cisco 2821 Router as an h.323 voice gateway router and CUCM 7.1.5 for call manager.  I recently changed telco providers and am seeing inbound calls on the caller-id come up differently than they did with the old provider.  For the most part all inbound calls show the name and number, which is how we want it, but we have a few customers that call in, and now since changing providers just their phone number shows up, not the name, but it did with the old provider.   So like I said call-id does work for the most part, but for certain customers that call it, it just stopped showing the name.  Its weird.  Would this be something on the telco side?  Her are my relevant caller-id configs:


isdn switch-type primary-ni

likely on provider.
call name display is not typically included with PRI installations. Caller ID, yes. But name display is something they like to charge for. since you are getting call name on some calls, it's likely you are subscribed to the service.
if you can replicate the issue, start with grabbing debugs on the isdn communications: debug isdn q931
grab a  good call (with call name) and a failed call (no call name). if the name is there on the failed call, but not showing on the phone, it could be a gw/ccm issue. Most likely though, the name is not being delivered by telco.
when opening a ticket with them, have the following available (or ability to reproduce as needed): calling number, called number, time of day. The debug will also assist telco.

Thanks. I agree its the provider.  Next time I am at this customer location, I'll make some test calls and do a debug from one that works and one that doesn't and compare.  Thanks.
