Prototipo de telefonía sobre la red IP de la universidad Cooperativa de Colombia seccional Neiva

Resumen

Through history Telephone Systems have played an important role as in the relation between people as in companies because it allow us to establish direct and worldwide communication. Signalization System Number 7 (SS7) must be implemented within Telephone Systems because this protocol is in charge to establish the call, the information exchange and the operations routing. Protocol SS7 gets its relevance on Voice on IP (VoIP) by the way it interacts with PSTN. It is an international standard implemented in Colombia as signalization system. Nowadays Telephone Systems have turned into an economy factor due to the reduction in telephone bills thanks to the VoIP technology in which the data net joins the net facilitating worldwide communication. Through this study a VoIP was designed for The "UNIVERSIDAD COOPERATIVA DE COLOMBIA" Neiva, to establish a communication system among the national branches getting a considerable bill reduction as the long distance calls. Protocols used by VoIP technology like H323 and SIP are important as well, because they allow us to establish internet communication, and gateway control protocols like SGCP and MGCP are used to control VoIP gateways . The developed study, consist in the design of a Voice on IP net for the existing data-voice net in the "UNIVERSIDAD COOPERATIVA DE COLOMBIA" Neiva allowing national communication between branches.
