How does the SIP REFER flow actually map to routing.interaction.created when using the WebSocket Notification API? GC sits at 2024-12.960.0. The Express listener catches the event, but it’s dropping the sip_refer_to field from the JWT payload. Signature checks out. Downstream Lambda handler won’t parse the transfer target URI anyway. Queue routing is doing jack all until that resolves.
