With innovations and advances, VoIP is emerging as the leading communications technology and the inevitable “phone system of the future.” Private Branch Exchange (PBX) phone systems have come a long way since their inception. Internet connections and widely-accessible broadband have transformed PBX systems into a data-dependent, digital delivery system for voice and multimedia communications. This new system is called a Voice-over-Internet Protocol network, or VoIP system.

By the end of 2014, experts forecast global IT spending surpassed $3.8 trillion, a 3% hike compared to 2013. Of this growth, researchers believe VoIP solutions represent at least 40%. If businesses sustain such spending habit, the VoIP marketing in particular could reach $80 billion over the next three years.
