VoIP Deployment: Getting Started

Before you know how much a VoIP deployment will cost and how 
successful it will be, you need to understand if your data network 
can carry high-quality voice transmissions. The odds are that a 
network upgrade will be needed to successfully deploy VoIP.

Consider the facts: Most “router-based data networks are not 
ready for successful voice deployment.” - Gartner Group

Your data network was originally designed to support emails, 
fi le transfers and deliver Web pages, not carry high quality voice 
transmissions. Voice traffi c is very time sensitive and can’t be 
queued like email or Web traffi c. Delays up to a half hour for an 
email or fi le transfer are generally not a problem, but delays of 
only a few hundred milliseconds can ruin a VoIP call, producing 
choppy conversations or dropped calls.

To ensure your VoIP deployment is successful and on budget, 
you need to fi nd answers to these important questions before 
deploying VoIP:

What type of VoIP MOS (Mean Opinion Score) call quality can 
I expect from my current data network for each business site?

Is network delay, loss or jitter the main problem impacting 
VoIP call quality, and how do I fi x it?

How many concurrent VoIP calls can my network carry without 
impacting existing data services?

Knowing this information before deploying VoIP will ensure your 
success, but what is the most accurate and cost effective method 
to obtain it?

Toshiba’s VoIP Assessment

The fastest and most cost effective way to determine your 
network’s VoIP readiness is to conduct a Toshiba VoIP 
Network Assessment.

The assessment quickly diagnoses the majority of your network 
issues so that by the time you begin your VoIP deployment, you 
have a converged network that will carry high-quality voice 
transmissions.

Organizations that skip this important deployment step experience 
poor call quality, dissatisfi ed users, upgrade cost overruns and 
delayed deployments.

Compare in Figure 1 the typical outcome of VoIP deployments that 
include a VoIP Assessment vs. ones that skip this important step:
