CDR Output

The following CDR AVPs must be observed in the same CDR. 

Acct-Terminate-Cause = Idle-Timeout
h323-disconnect-cause = "6"

Explanation

  • Acct-Terminate-Cause = Idle-Timeout: This standard RADIUS AVP indicates the call was ended due to a timer expiring.
  • h323-disconnect-cause = "6": This VSA AVP indicates the call was ended due to a timeout.
  • Acme-Disconnect-Initiator = 3: This VSA AVP indicates the call disconnect was initiated internally from the OCSBC, and not from an endpoint or due to an unknown reason.
