What You Need to Know Before Deploying VoIP

Companies are increasingly adopting VoIP as their standard voice system. VoIP reduces costs and increases business efficiency. Yet, many organizations don’t realize that deploying VoIP can have unexpected complications when it comes to its impact on network performance and other existing applications. For IT teams, the task of transitioning physically separate voice and data networks onto a single shared infrastructure without compromising the quality of either voice or data traffic requires new practices and procedures. Analysts and experts alike agree a pre-deployment network assessment is the crucial first step.

Gartner analyst Jeff Snyder has warned, 85 percent of networks are not ready for VoIP. And, starting the transition to convergence by assessing your network’s ability to handle VoIP is the only way to gain a complete understanding of the scope of the project. All pre-deployment assessments should be done prior to the purchase of any hardware and the assessment must include VoIP traffic simulation in order to gauge an accurate understanding of network readiness.

An Effective VoIP Assessment will:

• Measure the call load capability of the network

• Identify the faults and shortcomings of the network

• Provide a holistic view of the network’s ability to handle data and voice traffic

• Lower the project’s cost estimates

• Verify service level agreements (SLAs)

• Eliminate the network as a gating factor in the VoIP project

A complete end-to-end performance analysis should report on key performance indicators such as latency, loss, jitter, QoS, MOS, throughput and utilization to show how your network measures up!
