Validate design and implementation meets critical services design principles

1. Blast radius when equipment goes oos should be minimal by ensuring automatic failover to geo-redundant locations while preserving state without losing any transaction.
2. Vet scenarios that may cause silent outages.
3. Health check is E2E to ensure each process within the call flow is handled without error.
4. Each equipment in a service area pool has appropriate capacity to handle all traffic within the pool at any given time.
5. E911 traffic is prioritized during high volume events and single point of failure does not exist within the E2E call flow, including shared resources for IP/Signaling transport or within network environment.
6. Ensure call flow and measurement results meet FCC mandates for accuracy and PSAP termination.
7. Create test plan to cover each technology, call flow, and non-optimal scenarios to include failovers and/or retransmission.
