SipAvpCdr is a system feature that is responsible for building a Call Detail Record that reflects the actions taken whilst processing a session.

SipAvpCdr runs once when a session is ending and creates a CDR based on information gathered from session state, and then writes it out using the cdr-ra.

Tip

By default, Sentinel runs SipAvpCdr as the very last feature in the post SIP end session feature execution script. For example:

featurescript PostEndSession {
    run DetermineCauseCode
    run DiameterServiceInfo
    run SipAvpCdr
}
