## Voice Integrity Overview

### The Problem: Spam Labeling of legitimate calls

Analytic engines in the US are increasingly labeling phone numbers as spam leading to reduced call answer rates and increased blocking of calls due to negative reputation.

### The Solution

Voice Integrity lets you remediate spam labels on your phone numbers and eventually monitor their reputation.

Voice Integrity is a new Trust Hub offering that lets you register your phone numbers in order to:

* Remediate spam labels
* Monitor phone number reputation (coming soon)

Through Voice Integrity, you can register your Twilio phone numbers by using the Trust Hub REST API and console. These phone numbers will be registered with analytic engines for T-Mobile, Verizon, and AT\&T.

### What's coming up?

* In the coming months, we will integrate with the analytic engine for Verizon Wireless as well. If you have already signed up for Voice Integrity, there will not be any additional action needed. We will make automatically remediate the reputation of your registered phone numbers with Verizon Wireless when available.
