[Asterisk-Users] Accurate Billing

[John Todd]

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.
