| Requirement | Recommendation | Reason |
|---|---|---|
| Fast delivery | Use low-PDD routes and define failover retry behavior. | Verification flows are sensitive to user waiting time. |
| Short-call billing | Confirm 6-second, 20-second, or 60-second billing by country. | Billing increment materially affects high-volume short calls. |
| Playback | Use TTS, pre-recorded audio, or platform integration as appropriate. | Codes must be clear, stable, and repeatable. |
| Monitoring | Track failure codes, ASR, PDD, and playback completion rate. | Separates route issues from template or user-side issues. |
