Products affected: Phone ID

Changes

• New identity attribute added to Phone ID: The Active Call Status identity attribute allows you to check if the end user is actively engaged in an ongoing call. This helps prevent fraud by using ongoing call activity and type to determine the presence of Authorized Push Payment fraud.
• Use case: This identity attribute allows banks and and companies in the eCommerce/mCommerce industry to identify users who are suspected of being actively engaged in a conversation with a scammer.
• Flexible control: Active Call Status allows you to take extra steps when the end user initiates a transaction. If the end user is actively engaged in a conversation with a potential scammer, you can decide whether you want to allow the transaction.
• Information provided by Active Call Status: Based on the phone number provided in the API request, Active Call Status provides a true/false response (indicating whether the end user is participating in a call). It provides the information on whether the end user initiated or received the call and its duration.
• Coordinated coverage: Active Call Status works with other Phone ID identity attributes through the same API.

How this may affect you

• Select regional availability: This feature is currently available for customers with end users in select countries. To find out if this feature is available in your region, contact a Telesign expert.

• Cloud-based solution: QR Verify is a cloud-based, modular solution that enhances security and user experience by enabling a streamlined verification process using QR codes. Users verify their identity by scanning a QR code and signing a challenge with their registered mobile app.

Who is affected: Full-service customers
Products affected: Verify API

Changes

• New channel added to Verify API: Voice joins Silent Verify, Push Verify, SMS, WhatsApp, RCS, and email as a channel for Verify API, which allows you to set up phone-based, multi-factor authentication (MFA) using multiple channels and methods.
• Voice expands your verification options: The addition of voice as a Verify API channel provides a phone call as an additional method for authenticating end users via a one-time passcode (OTP).
• Send OTP codes in the language suitable for your end users: Using Text to Speech (TTS), you can select a supported language to specify the language that the service will use when delivering a OTP to your end user. If a language selection isn't provided, the default language, English (US), is used to deliver the OTP.
• Voice expands your channel fallback options: In addition to Silent Verify, Push Verify, SMS, WhatsApp, RCS, and email, voice increases your automated fallback options from one channel to another. For example, if SMS fails or times out because your end user's mobile device isn't working, the OTP can still be sent automatically using a voice call if voice is enabled as a Verify API fallback option.

Additional information

• Go to Verify API - Get started with voice in our developer documentation for more information on this new channel.
• If you would like to enable Verify API for your account and set up a Voice Caller ID that is needed for this channel, please contact us.
