VoIP Cost SavingsInfrastructure (Toll Bypass) is a relatively small part of the impact
But 23% isn’t bad…
Other impact centers around the premises equipmentThe two areas above may or may not be linkedDifficult to demonstrate hard saving on IP PBX and phone equipment alone
Individual results vary…

Final Conclusions
Convergence is all about migrationYou can leverage the best of the existing voice and data networks while deploying a convergence solutionNo one knows what convergence will bring in the next few years, so a flexible solution is a must
Converged Solutions, Not Technology are the Big Winners!
