Conferencing and collaboration services are big business and a growing trend. The global market forecast for audio conferencing is expected to reach $4.3B by 2015 (Statista 2014). As the sophistication and availability of smartphones, mobile apps, VoIP services and wireless plans improve, the means by which employees join conferences is rapidly changing and has a dramatic effect on the value of toll-free phone numbers. By 2015, there will be an estimated 1.3 billion mobile workers worldwide.
