How It Works

1
Developers select a helper SDK in programming language of their choice, write a few lines of code and send a voice-based message containing appropriate content for their use case such as alerts, reminders, notifications, promotions, registration/verification or other marketing messages.
2
The text-to-speech voice call request is submitted to the TeleSign communications platform.
3
The voice-based message call is made to the intended recipient using the best available route. TeleSign maintains multiple carrier routes around the world and utilizes a waterfall failover system through secondary providers in the event delivery failed over primary routes.
