Abstract

FIELD OF THE IDEA The idea described in this text refers to a method and system for making collected telephone calls in a package network environment for users interconnected through a package network, formed by a so called Soft Switch, a media gateway and an announcement/message generator. The Soft Switch is responsible for providing and controlling collect telephone calls resources directed to a Public Switched Telephone Network (PSTN). TECHNICAL BACKGROUND A preliminary analysis of the voice technology on package network is necessary to better define some devices that are crucial for this architecture, to which collect calls belong to, as well as specifying some common communication nomenclature and terms. The IP telephony technology, in package communication networks (for example, the Internet Protocol, IP), consists in using data networks with network protocols for making telephone calls and transmitting real-time voice in the form of data packages. Additional call and voice service protocols are implemented, which allow users to communicate with the same quality offered by conventional public system networks for switched telephone and mobile telephone public systems. These protocols are executed by network devices, so voice packages will not delay, or have their sequence changed or lost, assuring real time communication.
