DID recovery week: smoke A→B and lock the live From before production
Execute definitive A→B traffic tests and pin the exact sender address to secure your routes before live traffic rollout.
Recovery-week smoke is the A→B payload that locks the live From before production.
Prove the route with active payload verification
Messaging replies alone provide false confidence. A successful two-way echo test only proves that a handshake occurred, not that your primary messaging path remains clear of downstream filters. Before scaling automated traffic, you must execute a strict end-to-end smoke test. Send a synthetic payload from number A to number B through the active carrier pipeline, then verify that the payload registers instantly in your downstream ledger.
Pin the exact sender address in your routing ledger
Dynamic sender assignment causes unpredictable delivery failures if carrier gateways reject unrecognized CLI headers. You must bind your active alphanumeric string or numeric DID directly to the dispatch payload. When provisioning numbers via our JIT catalog, combine an instant prepaid hold with immediate ledger assignment. This guarantees that the sender address stamped on your outbound request matches the network gateway expectations.
Step-by-step pre-flight verification matrix
| Verification Stage | Action Item | Target Metric | Ledger Impact |
|---|---|---|---|
| Phase 1 | Dispatch test payload A→B | Under 2.0s latency | Reserve USD 20 floor |
| Phase 2 | Inspect CLI header matching | 100% exact match | Lock allocation ID |
| Phase 3 | Simulate downstream rejection | Zero silent drops | Verify prepaid hold |
| Phase 4 | Finalize production route | Live traffic ready | Soft review at USD 1K |
Establish financial controls and threshold reviews
Scaling unverified infrastructure introduces financial exposure. Maintain strict credit limits by enforcing a mandatory USD 20 floor for operational testing. As your throughput scales toward a soft review near USD 1,000/month, the platform automatically validates usage patterns against your prepaid reserve balances.
Connect your routing architecture with prior protocols
Successful recovery relies on a continuous chain of readiness checks. Before executing this final smoke test, ensure your foundational infrastructure meets all upstream carrier parameters outlined in DID messaging readiness before production.
Start with IOSOR
After recovery, send one payload from number A to number B on this route. Confirm the same bytes land in the ledger, then pin that From on the dispatch record. A handshake echo is not this proof. Leave the sender dynamic and production will stamp the wrong CLI.

IOSOR takeaway
Recovery week: A→B smoke plus a locked live From, not an echo badge.
Do: pin this DID’s sender before production. Don’t: scale after handshake-only.
