Somos, Inc. Extends Support for June 2021 STIR/SHAKEN Mandate with General Availability Release of RealNumber RTU


East Brunswick, NJ, April 20, 2021 -- Somos, Inc., a leading registry management and data solutions company, today announced that one of its cornerstone Authentication Enablement
Solutions, RealNumber™ Right to Use (RTU), has moved from its beta phase into industry General Availability (GA). The solution supplies a valuable tool that can be leveraged to provide confirmation of a number’s right to use, thus promoting increased confidence and trust in the calling number.

“It’s well known that the trust economy is in full swing and organizations that cultivate greater levels of trust are better positioned to thrive in this new era,” states Gina Perini, President and CEO at Somos, Inc. “RealNumber RTU helps underscore this by providing an authentication enablement solution that heightens consumer confidence while likewise supporting the June 2021 STIR/SHAKEN mandate.”

RealNumber RTU accomplishes this objective by validating the assignment by a Telephone Number Service Provider (TNSP) of a Toll-Free Number. One of its key differentiators is that it is the only solution whose baseline for validation comes directly from the Responsible Organization (Resp Org) of Record. Specifically, RealNumber RTU works with the Resp Org to ensure that only the data points relevant to validation are consumed. With the STIR/SHAKEN compliance deadline quickly approaching, RealNumber RTU can help enable enterprise customers to achieve A-level Attestation on outbound calls. 

“We’ve entered a period where it’s more critical than ever that calls are properly vetted, and caller identification is authenticated,” states Ryan Karnas, Director, Product Management at Somos, Inc. “RealNumber RTU was developed to help increase trust in the process while similarly providing a new key driver for consumer confidence.”

In addition to RealNumber RTU, the RealNumber suite also features RealNumber Do Not Originate (DNO), a solution aimed at helping to combat fraudulent and spoofed phone calls transmitted via a Toll-Free Number (TFN) by allowing Resp Orgs to flag TFNs as non-originating calls. Notably, TFNs that are not in an active status have been pre-loaded and flagged as DNO. RealNumber DNO is currently in its Proof of Concept (POC) phase and accepting participants.
