Robocall, Traceback and STIR/SHAKEN Expert

Questions for expert analysis

• What did the SIP and call-detail evidence establish about the call path?
• Which provider originated, authenticated, accepted or forwarded the traffic?
• Were traceback requests handled accurately and on time?
• Did onboarding, monitoring and mitigation controls correspond to the provider’s risk?

Evidence reviewed

• SIP Identity headers and attestation data
• Call-detail records and traceback correspondence
• Robocall mitigation plans and operational policies
• Customer due-diligence files and escalation records
• Traffic analytics, complaints and blocking actions

Opinion discipline

A carrier’s position in the call path is not by itself proof of knowledge, control or legal responsibility. The analysis should connect specific evidence to specific operational decisions and avoid conclusions that the record cannot sustain.
