The Red List™ caller profile database is a proprietary dataset of national harassing callers, voice spammers and call attack signatures.

The Red List database is powered by the intelligence we gather from the enterprise voice attacks and malicious caller interactions that we see every day.  Every customer benefits from Red List and it is a key ingredient in how we are able to continuously improve our ability to protect calls and network resources in a landscape where the threats are constantly changing and evolving.
