Voice Call OTP
Short definition
Voice Call OTP: A one-time verification code delivered to a user through a voice call. Call verification solutions are offered by Stream Telecom.
Meaning and how it works
An automated call can speak a verification code instead of SMS; retry limits help prevent abuse. Automated calls and verification flows start from events, rules or schedules. The system records their outcomes to determine subsequent actions.
Business applications
- Business scenario:
A user receives an automated call reading out a code to complete sign-in.
What to check before implementation
Define retry limits, appropriate contact hours and no-answer handling. Check recipient-consent rules and protect one-time verification codes.
