VoIP is spreading from the fixed-line world to the mobile world. Usage is on the rise creating significant opportunity for mobile VoIP gateway equipment suppliers as expenditures in this space are expected to soar beyond the $6 billion mark in 2015, says In-Stat
"Mobile VoIP has only recently begun being implemented in the business environment," says Amy Cravens, Market Analyst. "One of the key benefits of mobile VoIP for enterprises is extending desk phone functionality to mobile devices. Business-oriented solutions will essentially enable the users' cellphones to become an extension of their desk phones and will deliver, in addition to voice, a unified communications experience, including email, IM, and collaboration."
