- By 2010 PSTN revenues should no longer be carriers' primary source of revenue,
- In the developed world, carrier PSTN revenue will drop 16.7 percent by 2011.
- Because carriers have invested heavily in broadband, VoIP revenues should help to offset PSTN losses.
- Because VoIP services tend to be priced lower than PSTN-based services, carriers may still face a net revenue loss as VoIP.
- Carriers will face fierce competition from dedicated VoIP services such as Skype and Vonage.
