Bulk Export 400 on SIP Trunk Header Filter

  • Genesys Cloud v2.14
  • Bulk Export API v2
  • S3 Destination: EU-West-1

Can anyone clarify why the SIP_TRUNK_RECORDING export job fails with 400 Bad Request when filtering by sip_from_header? The payload is valid JSON, yet the error response cites invalid_filter_syntax. Standard call detail exports work fine. This blocks our chain of custody process for specific inbound trunks. Is the header field deprecated or requires a different syntax for legal discovery requests?
