VoIP telephone communication system

摘要

The system has an operator network comprising an authentication server (SR) to authenticate a terminal (M) e.g. personal computer, upon requests for elements of identity of the terminal. A Voice over Internet protocol (VoIP) server (SV) is addressed to the server upon reception of VoIP service request from the terminal. The VoIP server communicates temporary identity of the terminal, so that the server checks authenticity by comparing the identity with the temporary identity. The authentication server sends an acceptance message to the VoIP server to open VoIP service session for the terminal.
