Yes, but delivery quality must be excellent — if users dont hear the code within the first seconds, it results in failed authentication.

Use CLI-certified routes with good Answer Seizure Ratio (ASR) and fast Post Dial Delay (PDD) to ensure OTP reliability.

Avoid destinations that filter or block automated calls check compliance with local telecom regulations for OTP delivery.

Implement retry logic in your system in case of failed delivery, especially during peak times or for international numbers.
