Voice and data integration and interoperability. SIP-H.323 protocols translation simulator [articol]

Abstract

The VoIP protocols have now a very fast evolution and diversity. The paper presents a solution for VoIP service through multiple interconnected IP networks, each network using a different VoIP protocol: H.323 or SIP. Both H.323 and SIP are widely implemented as default VoIP protocols in data networks. Both protocols can be used for setting up Internet multimedia conferences and telephone calls. In order to achieve universal connectivity, interoperability between the two protocols is highly requested. That interoperability manages to a full protocol translation from one network to another and supports unified Voice service through the all networks. The paper presents such a H.323-SIP interconnection simulation program.
