Voice traffic up 12% in 2008, thanks to mobile

International voice traffic will grow an estimated 12.2% to 385 billion minutes in 2008, driven mainly by mobile, according to TeleGeography.

It forecasts that the number of mobile-originated IDD calls will overtake international fixed-line calls by 2009. Nearly one-third of international calls were placed from mobile phones in 2007, while 45% were mobile-terminated, TeleGeography said. 

It said cellular's growing share of international traffic was a result of subscriber growth in developing countries and the emergence of low-cost IDD calling plans.
