Abstract: Interpersonal communications initiated from devices such as various phones and voice/chat devices automatically transport via an optimal path by invoking a service selector of communication mediums for selecting at least one of several alternate routing paths for user communications from among available communication mediums common to both an initiator and recipient. A user registration database identifies communication mediums applicable to each user, and identifies or maps an appropriate communication medium between users for completing a particular call. The service selector identifies and intercepts an outgoing communication attempt (call, email, text) from a user, identifies the user and recipient in the database, and selects an optimal communication medium defining an alternate routing path from the initially specified (i.e. default) transport mechanism.

Abstract: A telecommunication appliance serves a large user base via an interface to a universal registration database having access to a set of transport mediums applicable to each user. A media database operates in conjunction with the appliance for identifying the user and providing targeted media to the user during a connection interval commonly referred to as the “ringback” period while a connection supporting the requested communication is completed. The universal identifier indexes alternate transport mediums available to the user based on entries in the universal database, and determines a lower cost (or no cost) transport. In lieu of the convention ringback, the initiating user receives targeted media referenced from the media database and responds to it while the communication is completed. The targeted media is provided as a fee based service to media provides (advertisers), therefore injecting revenue for supporting the service without requiring a fee from the invoking users.
