General Observations

� Industry cross-roads ahead

�VoIP 2.0?

� Customer expectations and needs

�Differ between the business market segments

� Changing business models

� It isn’t just about voice anymore….it is about media…

� 3G and 4G wireless technology choices

� “To what degree can the enterprise become wirefree?”


VoIP – and who is driving adoption today?

� The PBX manufacturers

� Still rule when dealing with the large enterprise

� The Carrier

� Wireless in-building coverage

� Managed services – traditional legacy mostly

� Channel Partners

� Large enterprise – Operators serve well as solutions are targeted toward them

� Branch operations are SMB-like

� Small Med Business – VARs and SIs

� The SMB problem

� Large and generally untouched VoIP market

� Complex deployment

� Many solutions available – mostly replacement technology

� No real new or innovative solutions have come available

Enabling the Vision

We see many of today’s business challenges solved through the convergence of IP and wireless mobility

� Common, flexible IP core supporting all types of business applications

� Wireline and wireless access optionsto meet unique needs across the business enterprise

� Managed services whereyou need them– Network Mgmt & Security– IP Telephony– Mobility

IMS


• Embedded mobile broadband

• Device optimized on a particular use

• User buys the devices from their retail

store at non-subsidized retail prices

• Freedom to purchase a subscription, ad

hoc usage, or a particular service

• The device is the customer

• The carrier subsidizes the device

and manages the supply chain

• Contracts and cancellation

penalties are required to recoup

the subsidy

MG/MGC converts TDM to SIP and moves call bearer channel to the edge.

IMS decouples call control from bearer channel. All voice and data sessions are simplified into media types.

New Sprint services

delivered to customer

Application servers are hosted within the Sprint network.

New services and applications developed to leverage IMS

Solid line – bearer

Dashed line - signaling

Enabling Mobility via IMS

MPLS


Summary

Customers want and expect a seamless, NOW experience

Industry paradigms are shifting rapidly relative to VoIP as well as the technology to support VoIP

Sprint has a unique vision for the evolution of its complimentary network capabilities

� Common service architecture
