PBX Installation and Maintenance Costsvery dependent on your network and contracts

IP Network Managementthe theory of managing one network

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!
