Voice routes for login codes and alerts,
with retries and quality monitoring.
Key checks for voice OTP routes,
short-call billing, and quality monitoring.
Login codes, risk calls, reminders,
alerts, and urgent notices.
Check minimum duration, subsequent increment, and rate by destination and route; do not assume 6-second billing.
PDD, ASR, playback completion, failure codes, retry interval, and destination reachability.
Submit target countries, peak TPS, daily volume, and playback method through the website contact form.
Confirm the minimum billable duration and subsequent increment by destination and route. For example, 20+20 means a 20-second minimum, then rounding up in 20-second increments. Published SIP rates list 20+20 and 60+60; the published SIP table does not list six-second billing; availability and terms require a route-specific quote and contract.

| 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 minimum billable duration and rounding increment by destination and route. | 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. |
