What is VOIP?
VOIP (Voice over Internet Protocol) replaces your traditional telephone lines with internet-based calling. Your phone calls travel over your existing internet connection instead of copper phone lines — resulting in significantly lower costs, more features and total flexibility to work from anywhere.
