Solutions for Mobile Operators

Mobile service providers are constantly evolving their networks to enable High definition (HD) voice and video communication services such as VoLTE, ViLTE (video over LTE), VoWiFi (voice over WiFi) and RCS (Rich Communication Services). As the demand for IP multimedia communications services grows, the desire to have high quality and secure real-time multimedia communication experience increases. While HD Voice implementation on mobile networks was a huge step towards that goal, the next generation IP communication infrastructure is transitioning to support full HD Enhanced Voice Services (EVS). EVS promises to revolutionize the voice communication experience with unrivaled quality, reduce cost of service, and open up doors for new service opportunities to mobile operators.

Identity Assurance - Robocall and Fraud Mitigation

What do your customers do when they receive a phone call from someone they do not know or a number they do not recognize? Perhaps they answer it, but far more likely they reject it, send it to voice mail, or just ignore it. In our current telecommunications world, everyone does this, because they are barraged by spam and robocalls and assume the worst – someone wants to pitch something I do not need or want, or this will be an attempt to defraud me.

With Ribbon Call Trust you now have a solution that you enables you to restore their trust in the phone. Even if you have an extension to the FCC requirement to implement STIR/SHAKEN, you still need to comply with the mandate to have an originating robocall mitigation program in place. With Ribbon Call Trust you can commit to your customers that you can meet the FCC mandate. In addition, you can add more value by being able to provide terminating robocall and fraud mitigation so your customers will be at much less risk from bad actors trying to get their private information or trying to prey on them with money scams.
