Today’s Environment

• Access to the PSTN for new entrants is still difficult to achieve in most markets

• These are the international markets where profit potential is greatest

• International LD is still king• Incumbents are slow to offer any

services that threaten their cash cow.


Today’s Environment – cont’d

• Most IP telephony deployments have been aimed at finding ways to access the PSTN surreptitiously

• ISR, leaky PBXs, GSM gateways• Legal action against IP telephony

operators happens everyday• High risk = High profit• The cycle continues


The seeds of change . . .

• Broadband access continues to spread• VoIP platforms, protocols and vendors

are maturing • SIP + softswitching decouples media

from signalling• Services can now be offered without the

PSTN in a commercially feasible way


The Paradigm Shift

Tired• Termination• H323• RADIUS billing• Gateways• PSTN• Invested• Building networks

Wired• Origination• SIP• Real time billing• IADs (IP Phones)• VPN• Hosted• Building Customers


Improving Technology breeds new Opportunities

Two examples . . .• Broadband voice - take advantage of

existing DSL/cable modem infrastructure. Voice services are an overlay (Vonage)

• Next-Gen callback – does not use the PSTN to originate the call
