Voice API Guides

These guides help you learn about working with the Voice API:

  • Masked Calling - Enable users to call each other, keeping their real numbers private.

  • Call Whisper - Phone numbers are everywhere in advertising: on billboards, in TV ads, on websites, in newspapers. Often these numbers all redirect to the same call center, where an agent needs to inquire why the person is calling, and where they saw the advert. Call Whispers make this so much simpler.
