Reason-Header AVP (3401)
The Reason-Header AVP (3401), is a UTF8 string that contains the content of the Reason-header detected by the SBC in SIP BYE, CANCEL, and SIP error responses. It may contain multiple entries if the system detects multiple reason headers. The system includes this AVP in the ACR for Accounting-Record-Type [STOP/EVENT] when there is an active account-config running diameter, and you have enabled the add-reason-header parameter in the sip-config.
The SBC expects this AVP in an ACR message, as follows follow.
| AVP | Number | AVP Type | Reference | Start | Interim | Stop | Event |
