The AVPs used by Sentinel SIP in the Accounting request are described.
Sentinel SIP population of Accounting Request
The Accounting Request message is defined according to IETF RFC 6733, and the diameter Rf interface is defined in 3GPP TS 32.299. Sentinel products use the definition in 3GPP TS 32.299 v12.11.0 for ACR.
This table indicates the top-level AVPs inside a ACR request and how the Sentinel SIP service populates them.
