I'll answer Kim's point more closely, since I know his configuration: you would need to have accurate call supervision (connect supervision/disconnect supervision) with messaging in order to have completely accurate CDRs. If your T100P hooks into a channel bank which then goes to a bunch of FXO lines which may or may not have 100% reliability for messages such as "busy", "congestion", or other error tone detection, then you may not get accurate CDRs. Your mileage may vary.
If your T100P is hooked to a PRI line with a D-channel, then you should get 100% accurate CDRs since that messaging is happening via digital signalling and not via tone detection.

What exactly would be classified as a digital ZAP device?
T1/E1 interfaces, so T100P, E100P, T400P, E400P
If you need to see examples, I could probably dig up CDR records where busy is indicated, and where no answer is indicated and there is a definate difference between call duration and stop-start duration.
