OCMS provides the Accounting Event API, an interface to create SIP event data that 
can be used for accounting and charging. The event output data can be post-processed 
to create CDRs.

The Accounting Event API consists of the following two interfaces:

■

oracle.sdp.sipservletframework.eventlogger.EventLoggerFactory

■

oracle.sdp.sipservletframework.eventlogger.EventLogger

The container creates an EventLoggerFactory instance available trough a 
ServletContext

 attribute with the name, 

oracle.sdp.sipservlet.EventLoggerFactory.EVENT_LOGGER_FACTORY

. 

The string cannot be used by itself, but must be specified as follows:

EventLoggerFactory elf =

getServletContext().getAttribute(oracle.sdp.sipservletframework.eventlogger.

EventLoggerFactory.EVENT_LOGGER_FACTORY

 The EventLogger interface is implemented by the loggers created by the 
EventLoggerFactory.getLogger(String loggerName)

 method. The  

EventLogger

 instances use Apache Log4j internally for the actual logging. Log4j 

allows flexible logging for instance to a file or to a centralized log server using syslog.

The EventLogger interface has three methods for logging events (illustrated in 

):

■

logEvent(SipServletRequest req, Map<Object, Object> 

additional)

■

logEvent(SipServletResponse resp, Map<Object, Object> 

additional)

■

logEvent(Map<Object, Object> event, String category

)
