CallManager ISDN Cause Code in CDRs vs H323 Cause Code

Does H323 have a way to send the PSTN ISDN Disconnect cause code to CallManager ? Are the CallDetailRecord databases and CallDiagnostic tables correctly showing disconnect causes for ISDN ?

I was under the impression that the IOS CCAPI didn't send ISDN Cause Codes to CallManager...

Cause codes are part of the q931 Disconnect message. They are sent by the IOS gateways to the call manager in the Disconnect message. You can see them in the CCM trace, or with "debug voip ccapi inout" on the gateway.
