Add a Call whisper to an inbound call

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.

These voice-based critical alerts are more persistent than a text message, making your message more likely to be noticed. Additionally, with the recipient confirmation, you can be sure that your message made it through.
