Description:

ClickSend’s current “Voice (TTS)” function is very limited for operational or monitoring use.

It simply makes one call, plays the message, and if not answered — that’s it.

No retry, no acknowledgment, and no callback to confirm that the message was actually heard.

For professional alert and monitoring systems, this is critical.

In a true TTS alert flow, the call must:

Retry unanswered calls until confirmation or timeout,

Require the receiver to press a key (for example “1”) to acknowledge,

Optionally trigger a webhook or email once acknowledged.

Even smaller providers (like tts.message-service.org) already include this logic — their only weakness is poor voice quality.

ClickSend, being part of SINCH, already has world-class infrastructure and voice synthesis — but without retry/ack logic, the system behaves more like a demo than an enterprise TTS service.

Adding this feature would instantly make ClickSend’s Voice API suitable for critical infrastructure alerts, NOC/SOC notifications, and automated safety systems — all areas where SINCH already has strong credibility.

This is not a “nice-to-have” feature — it’s what turns a message broadcast into a true interactive alert system.

Please escalate this request internally; it deserves to reach product management level.
