Last week I described the PSTN as simply a legacy user interface to today’s communications networks, based on the fact that most of the core network is already VoIP. The PSTN is simply the average person’s experience of an all VoIP network. While the description of the PSTN as UI drew some comment, nobody argued that the core was anything but VoIP.
This morning I draw your attention to two more facts to back the assertion that VoIP is everywhere, even if not widely visible.
Tomorrow XConnect will announce their growth from last year – near doubling of revenue, 81 percent growth in IP traffic, a 108 percent rise in routing queries on its ENUM registry, and 64 new interconnect customers. This from a company who’s inglorious mission is simply to connect one IP carrier to another.
In mid-January, Telegeography published research showing that Skype last year carried 54 billion international voice minutes – nearly 12% of the global international voice traffic. That’s one company, all IP. Skype has an innovative GUI for users, but also provides local dial phone numbers in many countries, for those who would prefer the legacy user interface — the PSTN.
The revolution continues.
And now back to our regularly scheduled programming.
