Buyers guide


Last Updated: May 25, 2019

Business phone service has transformed dramatically over recent decades—so it’s critical to know your options if you’re thinking about switching providers or replacing your phone system.

Recent changes in carriers’ offerings have mainly been driven by the evolution of Voice over Internet Protocol (VoIP) technology. VoIP makes it possible to send phone calls over the Internet, as opposed to traditional phone lines.
