A growing number of small businesses are switching from traditional landlines to VoIP (Voice over Internet Protocol) systems. While it can be an uphill task to overhaul the entire telecommunications system of any small business, it is definitely worth considering in light of the ever-increasing costs of traditional services. In fact, according to In-Stat, almost 79 percent of American businesses use VoIP phones, a 37 percent increase since 2009. VoIP is a method of making phone calls using the internet as opposed to using typical landlines. VoIP services integrate IP phones, which look pretty much like traditional office phones, except they plug into an internet connection with an Ethernet cable.
