In the past, business communications were confined to an office phone system. Important company collaborations were limited to a conference room. However, companies and technology have both evolved to support online business models that are driven by an increasingly mobile workforce. One of the fastest growing business communication technologies is Voice Over Internet Protocol (VoIP). VoIP technology eliminates the need for conventional phone lines and makes it possible to transmit voice calls through an internet connection by using your smartphone, tablet, or laptop.
