The Call-ID of outbound registrations was the sip_gateway_sid, the same on every SBC. When the regbot role moved to the other SBC, the registrar saw a refresh of an existing binding from a different source address and Contact. Some registrars 200 such a refresh without updating their routing, so inbound calls to the registered trunk fail with 404 until the binding is recreated. The Call-ID is now sip_gateway_sid@<sending SBC public IP>: stable across refreshes and restarts of one SBC, new when the role moves, so a move looks like a new registration. register_status also records the sending SBC as sbcAddress. With AWS_LIFECYCLE_DRAIN enabled the sidecar polls IMDS autoscaling/target-lifecycle-state (the signal inbound drains on; detection only, inbound completes the lifecycle hook). When the instance is being scaled in, the regbot holder releases the lease while still running instead of after the instance is gone; until now the draining SBC kept the registrations, so carriers kept sending registration-trunk calls to an SBC that answers new INVITEs with 503. It never claims the role back. Once another SBC has claimed it, the draining SBC un-REGISTERs (Expires: 0) the bindings whose Contact carries its own IP. Bindings with an AoR or realm Contact are left alone: the new SBC sends the same Contact, and its REGISTER has already replaced ours. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
