One or more participants in a communication are authenticated using an authentication metric such as a face print or voice print. A single telecommunication address (or one for each participant) that is not associated with a communication device and is associated with at least one of the participants is determined. The telecommunication address (or addresses) is sent during the initiation of a communication session.Other embodiments provide for sending a single associated telecommunications address, individual identifiers of each of the participants, and a communication device name to better identify exactly who is calling. The system can also detect when an additional participant has joined the communication session and when a participant leaves the communication session.
