Juniper Research: Mobile VoIP minutes to double each year, reaching 470.6 billion by

The number of mobile VoIP minutes will rise from 15 billion this year to 470.6 billion minutes by 2015, finds a new report from Juniper Research. According to the research company, the traffic will steadily rise in all regions over the forecast period, but particularly in developed markets.

Juniper’s Senior Analyst Anthony Cox points to two “flavors” of mobile VoIP traffic – one that uses cellular 3G and 4G networks, and WiFi mobile VoIP, which is operators hate (and users love) as its “costs” them lost minutes.
