Voice over Internet Protocol (VoIP) continues to grow rapidly in both consumer and business markets. For businesses, VoIP offers cost savings through reduced long-distance charges and combining voice and data networks. It also provides increased functionality by allowing employees to work remotely with a good internet connection. During disasters or increased call volumes, VoIP can provide an on-demand call center solution. As VoIP and its applications mature, businesses will see additional benefits beyond basic phone functionality.
