Voice Integrity to Remediate Spam Labels

That’s why we’re excited to introduce our new product called Voice Integrity, designed to help you improve your call answer rates and reduce blocked calls due to negative reputation by remediating spam labels on your phone numbers.

What is Voice Integrity?

Voice Integrity is a new offering alongside the SHAKEN/STIR and CNAM Trust products that will let you register your phone numbers in order to make sure they are not mislabeled as spam.

As part of Public Beta, you can register your Twilio phone numbers via Trust Hub which will then register them with the analytic engines responsible for running spam labeling algorithms on AT&T and T-Mobile.
