With AT&T how can you identify what DIDs are associated with a particular PRI?

How can you tell what DIDs are associated with an AT&T PRI? I've migrated pretty much all of my traffic to a SIP circuit and I want to start cancelling circuits.
Should the circuit ID to DID mapping be on the bills?

DIDs are usually provided in blocks. But yes, the numbers should be listed on the bills. Also check for numbers that have been ported that you're still getting billed for. (An old employer of mine got billed for like 3 years on some numbers that had gotten ported, but the old carrier declined to remove from the bill)
