Amazon Chime proxy phone sessions let you provide two users with a shared phone number to communicate via voice or text for up to 12 hours without revealing personal phone numbers. When users call or message the provided phone number, they are connected to the other party and their private phone numbers are replaced with the shared number in Caller ID. Personal phone numbers are not displayed, a method often called number masking. With proxy phone sessions, a food delivery service can allow a delivery driver and customer to contact each other for the duration of the delivery period to get information like a gate code or other special instructions. Proxy phone sessions help protect user privacy and keep transactions on your service. Numbers are available on-demand, so developers don’t have to calculate how many numbers they will need for different locations, or pay for extra numbers they do not use.

We are pleased to announce that Amazon Personalize now provides recommendations scores with each personalized recommendation. These scores can help you understand the relative difference in the relevancy of recommendations, and help you apply additional business logic on the recommendations, such as filtering out recommendations below a threshold or balancing relevancy with other business objectives such as displaying sponsored content.
