A UK-based research group recently reported that the total number of mobile VoIP minutes will jump from 15 billion in 2010 to 470.6 billion by 2015, thanks to the proliferation of 3G and 4G networks. Juniper Research says the biggest boost will come from the U.S., which will account for 135 billion mobile VoIP minutes by 2015 and they forecast that there will be 100 million mobile VoIP users by 2012.
“There are several flavours of mobile VoIP,” says Anthony Cox, Senior Analyst at Juniper Research, noting that operators fear losing traffic to Wi-Fi networks most: “Wi-Fi mobile VoIP is potentially the most damaging of all VoIP traffic, as it bypasses the mobile networks altogether,” he says. “We forecast that mobile VoIP over Wi-Fi will cost operators $5 billion globally by 2015.” .
For next generation VoIP network operators these numbers represent a significant opportunity to capture the lucrative mobile smartphone subscriber through mobile VoIP Wi-Fi softphones and through mobile dialer/callback applications which are tightly integrated into the native dialer and contact management of the phone. Traditionally, third party VoIP operators targeted residential land line subscribers, businesses and travelers, however with the growing number of smartphone users worldwide and the computing power of today's smartphones, their services can now focus on the fastest growing voice market, which is mobile. .
