Chapter 4 VoIP RADIUS Accounting Configuration
4.1 RADIUS Accounting Feature of XE IP PBX
The Remote Access Dial-In User Service (RADIUS) protocol is an industry standard
protocol for authentication, authorization, and accounting (AAA) of access server
connections.
The VoIP RADIUS function provided by the XE IP PBX is a simple accounting function,
not supporting authentication and authorization for the time being. It is suitable for use
by enterprise-level users for VoIP call accounting. When a VoIP call takes place, the XE
IP PBX encapsulates the user information and call information in the RADIUS
accounting packet and send the packet to the RADIUS server to trigger accounting on
the user; when the call ends, the XE IP PBX reports the statistics information of the call,
including the calling number, called number, and call duration to the RADIUS server to
complete the call accounting.
The XE IP PBX processes call accounting packets in the “start-stop” manner. Namely,
the XE IP PBX sends an accounting request message to the RADIUS server at the
beginning the end of call setup. Nevertheless, the XE IP PBX directly initiates or
releases the VoIP call, having or having not received a response from the RADIUS
server or not.
The accounting policy of the XE IP PBX is based on the calling user, rather than the
called user.
