The Voice Market

Changes, Shifts and Predictions

3 December 5, 2007 [Enter presentation title in footer] Copyright © 2007 CA

Industry Direction

> Evolution to IP Technologies

� IP Phones

� Unified Messaging

� VoIP

> Heterogeneous (IP and TDM)

voice networks

> Convergence of:

� Networks (data and voice)

� Organizations (IT and telecom)

� Companies (M&A)


World Voice Market Information

> Worldwide IP PBX Revenue Up 23%, TDM Systems Down 15% in 2005,

with revenue total $8.1 billion.

> Hybrid PBXs accounted for 65% of 2005 PBX revenue, TDM 23%, and

pure IP 12%; hybrids and pure IP will continue to increase through 2009

at the expense of TDM.

> IDC estimates that 60% of new PBX shipments will be IP based by

2009. Annual revenue is forecast to grow to $11.4 billion in 2009, driven by strong IP PBX sales worldwide as more organizations move to voice over IP.


Voice Market in APAC

> 44% of 2005 PBX systems revenue came from EMEA, 32%

from North America, 19% Asia Pacific, and 5% CALA.

> Voice Market is still dominated by TDM in Asia.

> Biggest contributor to Voice Market are India and Philippines as

they are the 2 largest outsourced Call Center in the world.

> IP telephony market in Asia Pacific (excluding Japan) in Q305

was pegged at $212.99 million, up 15.58% quarter-on-quarter.

It stands at $30.50 million growing at 8.17%

> Unrestricted IP Telephony will boost IP-PBX shipments to over

25% of PBX (totaling $140 million) line shipments by end-

2006, but low PSTN tariffs will constrain VoIP usage.

Voice Management Challenges

“I only find out about

problems when my

customers call the help

desk to file complaints –

that’s too late!”

“When a problem occurs there’s

too much finger pointing. I don’t

care where the problem is I just

want it fixed and FAST. I have

service levels that need to be met!”

“We can’t set priorities based on

the impact to the business.”

“I need help. I’m being

asked to rollout VoIP

services at the same time

I’ve got to handle more

with a reduced staff.”

Assessment is Critical!

“People were told that VoIP is going to be the

greatest thing,” says William Stofega, VoIP

research director at IDC.

“But in some cases, people didn't do the

necessary network planning. Ninety-nine

percent of all VoIP network implementations

that fail do so because IT departments didn't do

their homework.”
