An overview of Number Voice API and Use cases

Sendchamp's advanced Number Voice APIs and elastic cloud infrastructure make it a breeze to build modern, dynamic, scalable, fully-featured voice applications that reside entirely in the cloud.

There are a few different ways to utilize these services, so we also encourage you to browse the documentation for our APIs.

Some Voice Applications/Use cases you can build with our APIs include:

  1. Call Center application.
  2. Call Campaigns/Blasting/Robocalls
  3. User authentication (Two-Factor Authentication, OTP Voice Calls)
  4. Call Tracking
  5. Interactive Voice Response Apps (IVR)
  6. Global Conferencing

NB: We are constantly improving this documentation and will update the use cases with tutorials to make it easier for you to follow.
