    This article provides a guide for White Label Partners on how to add a native fax account to a user within the Manager Portal, detailing the available methods and inbound fax handling options.

    Scope

    This document will show you how to add a fax number to a user and explains the methods available and handling inbound options.

    Requirements

    • White Label Access to Manager Portal
    • DID Treatment must be set to available
