Method of VoIP Network Performance Optimizing

Existing approaches to routing calls in Voice Over IP networks interacting with several IP-telephony providers are considered. The mathematical model of voice calls routing and its analysis and optimization have been described. Method of Voice Over IP network performance optimizing based on voice call routing automation and core IP-network reorganization to increase the cost / quality ratio of Voice Over IP communication which gives an average of more than 20% increase in quality indices without a significant increase of conversation cost has been developed.
