VolteInterimCdr
is a system feature that is responsible for writing interim Call
Detail Records throughout the session.
VolteInterimCdr runs at various key points throughout a session and if any of its write conditions are met, it will create a new interim CDR based on
session state, and write it out using the cdr-ra.
|
By default, Sentinel runs featurescript SipEndSession-SysPost-Default {
run VolteInterimCdr
run MaxCallDuration
run SessionRefresh
}
