Live Answer Detection
Is it Live or Voicemail?
With Varolii, You'll Know Every Time
Varolii’s own patent-pending algorithm uses a mix of Enhanced Call Progress Analysis (ECPA) and social engineering to achieve virtually 100% accuracy in differentiating a live answer versus an answering machine.
The delivery of a voice message is a dynamic process requiring an interactive listening-prompting solution. We have several methods of increasing accuracy to determine whether a recipient is a voice mail or live person. These methods include listening to initial energy, length of that energy, prompting the user to DTMF and listening for interruptions.
All combined, you know whether you've reached the person live - and can take the proper action.
You couldn't ask for a better strategic partner... I say this because not only does Varolii offer an extremely efficient value add, they also offer a huge amount of intelligence and knowledge in the area of credit collections.
