Verify Your Customers with Voice Calling Two-Factor Authentication

With more than 8.8 billion mobile internet subscribers and consistent year-over-year growth, mobile continues be the preferred communications channel by consumers.

To capitalize on this trend, companies must embrace their digital transformation by finding more ways to reach more customers across mobile communications channels while keeping their data secure.

Importance of Voice Capabilities

Syniverse has developed a solution that allows businesses to verify customers beyond SMS with two-factor authentication (2FA) over a voice call using one-time passwords (OTP) and text-to-speech technology.  This voice-based solution powered by Syniverse CPaaS Concierge—our global communications platform—unlocks the agility and reliability to reach customers around the world on nearly any phone number, regardless of if the device is mobile, virtual or a landline.  If a phone number can receive a call, the customer on the other side can receive the OTP over voice.

Expanded Capabilities

This Syniverse Communications Assistant service allows businesses to easily and automatically trigger OTPs at any touchpoint to their customers.  With text-to-speech, a written message is converted to an audio message in their desired spoken dialect and then either sent to the customer over an outbound call or directly to their voice mail.  Syniverse has coverage to over 200 countries with the support of over 100 various languages and local dialect translations

Whether the outbound context is a written text message or a voice recording, our platform will consume the data payload and seamlessly deliver the content using the ubiquitous voice communication channel. And by embedding this into a simple integrated solution, businesses can effectively save overall project development costs and time to market of desired services.

Visualizing the Solution

The voice communication channel on Syniverse CPaaS Concierge allows for two-way integration using the digit collector and dial tone multi-frequency services to capture end user input. The digit collector service can be used to collect digits of the numbers entered on the phone during a call. While the dial tone multi-frequency service can play DTMF tone that can be used to advance in a menu selection or trigger a response. Both services, the digit collector and dial tone multi-frequency content entered by the mobile user is collected and posted back to the partners application via the webhook connection.

Mobile-first engagements continue to rank as preferred method of communication for customers. Through the use of voice calling API service, companies can easily exceed customer and partner expectations.
