Method for providing telephony courtesy function e.g. conferencing and call-relaying, involves setting up link between caller and telephone server once authorization is verified

摘要

A method for setting up a telephone link by using a telephone server which can be dialed via an assigned directory number and can lay on courtesy telephony functions for an authorized caller. Initially the telephone server is called by the call-signal from the caller and the telephone server receives the call-signal, followed by identifying the calling party by the telephone server so as to confirm whether caller is authorized for the telephone function. During the verification procedure, if the caller is authorized, a link between the caller and server is set up and several courtesy telephone functions are made available for the caller through the server. Independent claims are included for (1) a telephone server; and (2) a computer program.
