Agenda
A better way to improve productivity
Why IP telephony & UC
In the Beginning - The unexpected truth
Barriers - IP telephony or What?
1,200 companies -60% underestimated cost. Don’t be next. Find out why?
Which Paradigm are we working from?
10 Questions that can save you money and stress.

Improving Productivity
There Is A Better Way!
4
Why Migrate to IP Telephony and Unified
Communications
1. Cost savings
2. Higher Productivity
3. Improved Service Levels
4. Future technology
5. No more or costly support costs.
“The important dividing line will be between those who see VoIP as just a new way to do the same old thing and those who use it to rethink their entire business”

Key Components To Your Success.Migrate To Unified Communications With Confidence
Allocating More Budget On Application and Training While Ensuring An Optimized Local Area Network For Convergence

How It All Started Great Offering, Challenging Experience.
Let’s Packetize Voice and Put On The Data Network?
“Voice Is Just Another Application”
Facts:
•VoIP started in mid 90’s driven by Data Invention - Vocaltech.
• Data Network Manufacturers established standard deployment method for Business.
7
LAN Topology Option - Separate Networks for Voice and Data
Separate Voice and Data switch networks centrally converged.

Customer Barriers – Network Driven

How About You?
Are Your Barriers Similar To Those
15
Barriers Are Justified
“60% of 1,400 companies under estimated LAN readiness Costs.”
What do you think the cost per port was?
$421 per port.

Quick Facts - Nemertes
Add facts
17
Industry Paradigm Established
Manufacturers of technology create solutions from a technology out perspective.
At times, this perspective results in not fully appreciating customer requirements to have technology working in the real life situations
Voice on data LANs is one such paradigm.
18
Customer Paradigm
Customer want UC and IPT valueWhat required to ensure good user experience?What Does IP voice really need?Reduce Risk & Cost while delivering value.
“We can't solve problems by using the same kind of thinking we used when we created them.”
Einstein
