Webinar - Effective STIR/SHAKEN and Robocall Prevention Solutions that Work Today
By Special Guest
Unwanted scam robocalls with spoofed caller IDs are a menace to consumers and businesses. These calls threaten the viability of the telephone network. Why keep using and paying for a service where a large percentage of the calls you receive are aggravating robocalls? How can businesses serve customers who are reluctant to answer their calls?
The telecommunications industry has developed a technology framework, STIR/SHAKEN, to combat caller ID spoofing. The framework enables originating service providers to authenticate and sign caller ID information in outbound calls. Terminating service providers then use this information to verify caller ID information on inbound calls as they deliver them to subscribers.
The technology isn’t designed to identify and block scam robocalls, but it does identify spoofed caller IDs—an important tactic used by scam robocall perpetrators. If you can identify spoofed caller IDs, robocall prevention measures become much more effective.
But what can voice service providers do today to prevent scam robocalls? And how will STIR/SHAKEN change robocall prevention methods in the future?
STIR/SHAKEN is based upon a triangle of trust. Together, the Policy Administrator, Certificate Authorities, and Service Providers use public key infrastructure and digital certificates to make the STIR/SHAKEN reliable and trusted.
There are several robocall prevention methods that can be used in conjunction with STIR/SHAKEN:
- Calling number reputation service
- Invalid or unallocated calling number detection
- Neighbor spoofing prevention
- Dynamic traffic analysis
STIR/SHAKEN doesn’t replace these methods—it makes them more effective.
As of this writing, many voice service providers have begun using STIR/SHAKEN. The portion of calls authenticated and verified across the network is small, but it will grow.
Service providers should begin using STIR/SHAKEN along with these robocall prevention measures today. We have seen service providers successfully identify and block large numbers of robocalls with these techniques. As STIR/SHAKEN becomes used more widely, robocall prevention will become even more effective.
Register for the TransNexus (News - Alert) webinar, Effective STIR/SHAKEN and Robocall Prevention Solutions that Work Today, to learn how these robocall prevention methods deliver effective results today and will become even stronger with STIR/SHAKEN.
