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.

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
