Number masking helps protect the privacy of communication by anonymizing the original phone numbers of the parties involved. It uses an intermediary virtual number that masks the actual numbers during the call. Plivo's Number Masking API is designed to seamlessly manage both the assignment of virtual numbers and the entire call flow process. To initiate a masked session, simply send an API request including the real phone numbers of the call participants. In response, Plivo allocates a virtual number from your account that facilitates the masked session.
