VoIP Basics

VoIP Voice over IP (VoIP) is a network technology that enables telephony communications over an IP network. VoIP enables an organization to implement its own telephone system using an IP-based network and VoIP devices. Using VoIP can save an organization money because the organization can use its existing network for its internal telephone service and for long distance calls. VoIP services are also available to residences and businesses through cable TV, satellite, smartphone/ cell phone, and private VoIP providers. A VoIP network generally consists of at least three types of devices. First, there is a telephone device (for example, a VoIP-capable computer, telephone handset, cell phone, or smartphone) that is used to convert voice sounds into binary (ones and zeros) and then into IP packets. The telephone device communicates with a second type of device, a call processor or call server, that is able to: • Set up and terminate calls • Route calls • Manage a calling session • Translate telephone numbers or IDs into IP addresses
