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

It 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.

Warning This feature is deprecated and not enabled by default. It has been superseded by the VoLTE SIP AVP CDR feature

Statistics

VolteSipLegacyCdr statistics are tracked by the volte.sentinel.sip SBB and can be found under the following parameter set in REM:
SLEE-Usage → volte.sentinel.sip service → volte.sentinel.sip SBB → feature → VolteSipLegacyCdr
or with rhino-stats:
"SLEE-Usage.Services.ServiceID[name=volte.sentinel.sip,vendor=OpenCloud,version=2.7.0].SbbID[name=volte.sentinel.sip,vendor=OpenCloud,version=2.7.0].feature.VolteSipLegacyCdr"

Name Description

Functionality

This features uses the information from the session state fields mentioned above and constructs a protobuf message out of it for output. See Legacy CDR Format for the format of these messages.

Also see Charging Information for general information about the contents of CDRs and CCRs.

Note This feature only supports writing binary CDRs. If the cdr-ra is configured to write string CDRs the feature will fail to execute.
