Error: Missing required field: trunk_id in Analytics API v2 export. Architect flow v14.2.1 routes 15 AP-Southeast-1 BYOC trunks. SIP headers intact on ingress, yet conversation_uuid mapping fails for secondary carrier failovers. Trunk config shows valid SIP credentials and routing profiles. Data loss occurs specifically during high-volume peak hours, correlating with SDP re-negotiation delays. Is there a known latency threshold causing metadata drop in the analytics pipeline for multi-trunk setups?
