Industry Trends
Customers want to move to VoIP
IP Telephony is expected to surpass traditional
telephony by 2006.
but they want to take it slow.
Customers have told us
Its too expensive to replace the entire phone
system for our company all at once. Im
interested in testing out VoIP without making a
full migration right now.
Thats why were suggesting a phased approach to
VoIP migration.
Customers can migrate to VoIP over time. They
keep the benefits of their Centrex/Plexar system
while upgrading to VoIP in more manageable phases.

The Business Challenge of VoIP Migration
Problem losing abbreviated dialing

• When a customer migrates to VoIP in phases,
  legacy Centrex/Plexar users cant use abbreviated
  dialing to call VoIP users.

For example A Centrex/Plexar client chooses to
migrate one building to VoIP. Centrex/Plexar
users in the other building would not be able to
use abbreviated dialing to call VoIP users.

A Centrex/Plexar phone uses abbreviated dialing
to call a VoIP station. At the Central Office,
the DPAS database matches the abbreviated dialing
extension to the stations complete ten-digit
phone number. DPAS routes the call to the VoIP
stations complete ten-digit phone number through
the PSTN. The call travels through an IP
Network and arrives at the VoIP station as a
normal call.

Market Fits

• DPAS is intended for business customers who

1. Currently use Centrex or Plexar, and
2. Are considering migration to a VoIP solution

• Good candidates for VoIP migration tend to share
  three common characteristics
• A large volume of Centrex/Plexar stations, which
  makes phased VoIP migration an attractive and
  cost-effective option.
• Attitude of risk-aversion in adopting new
  technology (want to invest slowly rather than
  flash-cut to a new system).
• Many competitors who are already switching to
  VoIP (in industries such as education and
  healthcare).
