Implementación de ss7 en una red cisco interconectada a una pstn

Abstract

This project consists on the implementation of protocols IAX, SIP, SCCP within a CISCO network that shall be interconnected with a public switched telephone network (PSTN) using the signaling protocol number 7. We need a unified communication server called ELASTIX, which works with the operating system "CENTOS"; also; we are going to use CISCO equipment, such a, Linksys SPA 3102, which works as voice Gateways, all our devices will be connected to the router C881-SRST in order to work with an internal company network. During the testing periord, we will make calls to verify the performance of each protocol. These calls will be tested with the protocol analyzer named WIRESHARK, whose functionality is to provide a complete analysis by a graphical interface. Also we will show many characteristics of the CISCO PGW 2200, which is a Voice Gateways where you can configure the SS7 signaling used to interconnect a central telephone with IP networks. With the test outcomes we will demonstrate that the calls will be connected and analyzed through the mentioned protocols
