I was looking at maps on the TeleGeography site and I ended up on their mailing list. This is something they sent me about International voice-over-IP traffic. I was surprised that it now accounts for 11% of international calls – and more in India/Pakistan/Bangladesh. I know of services like www.skype.com, but I’ve never used VoIP myself. I do hope it grows faster –
“International voice-over-IP traffic grew 23 percent in 2003, respectable by most standards, but far below the 80 percent growth rate of previous years. Global VoIP volumes appear to be reaccelerating in 2004, however, and should achieve 40 percent growth by the end of the year.
“The slowdown in 2003 was due, in part, to the growing maturity of the industry, and partially due to temporary setbacks in a few key destination countries,” said TeleGeography analyst Patrick Christian.
Despite this temporary slow-down, VoIP is still growing at twice the rate of traditional switched voice, and now accounts for 11 percent of international calls. According to TeleGeography’s latest research results, global voice traffic reached nearly 200 billion minutes in 2003, 22 billion of which was carried over the Internet. The impact of VoIP technology is greatest on routes into developing markets, where high settlement costs make VoIP a worthwhile alternative. For example, VoIP traffic to India, Pakistan, and Bangladesh more than doubled in 2003. In markets like these, VoIP can account for a quarter or more of incoming calls.”
