Market research firm TeleGeography reports that Skype’s international traffic volume continues to grow significantly. TeleGeography estimates that Skype’s on-net (Skype to Skype) international traffic grew 36% in 2013, to 214 billion minutes. By comparison, International telephone traffic from fixed and mobile phones continues increasing by 7 % in 2013, to 547 billion minutes. While international PSTN traffic still carries most international traffic, Skype’s minutes are growing more rapidly: in 2013, Skype added 50 percent more than the combined international growth of every telco in the world.
Commenting in a statement on the trend, TeleGeography analyst Stephan Beckert said, “The rapid spread of OTT services is making life ever more challenging for international service providers, but the PSTN will not disappear anytime soon. No other network comes close to matching the global reach of the PSTN. While Facebook has approximately 1.2 billion monthly users, at year-end 2013, the PSTN connected to just over 8 billion fixed and mobile subscribers worldwide.”
