Developing a network design that is resilient and cost effective provides the best environment for a successful VoIP system. Wherever possible when designing the new network we factor the five 9′s approach.  Before deploying a VoIP-enabled network, we always do a thorough assessment to identify the current environment and network goals including but not limited to:

• Review of the current switch/router environment
• Review of current and future data network for topology and bandwidth
• Evaluate the policies related to possible security vulnerabilities
• Consideration of the vulnerability to break-ins
