What is a Voice API?
With a voice API, you can create, manage and control automated voice calls.
Technically speaking, a voice API (Application Programming Interface) enables developers to integrate voice communication functionalities into their applications, websites and services. And for you, this means direct access to all Voice API functionalities from your own tools, without having to use another interface. An efficient, robust solution for all your automated customer services.
