You can administer the system to display call charges on CDR reports. For more information, see the Call Detail Recording
feature.
Either the ISDN C C field or the PPM field in the CDR record contains the last cumulative charge received from the network. If Call Splitting or Attendant Call Recording is enabled, and a call is transferred for the first time, the ISDN Call Charge field contains the cumulative charge that was most recently received from the network.
For all subsequent transfers, the ISDN Call Charge field contains the difference between the cumulative charge that was most recently received and the value that was generated in the previous CDR record for the same call.
The system displays a zero in the Call Charge field when:
No AOC information is received
A value of zero is the last charge information that was received
The outgoing trunk group is not administered for AOC or PPM
