On Defining VoIP Telephone Systems
VoIP sends packetized voice-over an IP network. Typically, the IP network serves as a data network too, causing potential quality and security issues. Fortunately, most infrastructure manufacturer's provides a collection of quality of service (QoS) and security measures to ensure the quality and security of voice transmissions.
The capability to transmit voice-over an IP network (as an example, the Internet) allows many corporate networks to readily interconnect their sites without purchasing dedicated leased lines between their sites or depending upon the public switched telephone network (PSTN), which imposes charges for several call types (for instance, cross country and international calls).
With the arrival of VoIP technology, some confusion has arisen around its associated nomenclature. For example, look at the terms VoIP and IP telephony. Both make reference to sending voice across an IP network. However, the principal distinction involves the endpoints in use. For example, in a very VoIP network, traditional analogue or digital circuits connect into an IP network, typically through some type of gateway. However, VoIP telephone systems contain endpoints that natively communicate using IP.
To further illustrate the excellence between VoIP and IP telephony, look at the drawings below. In the top portion of the figure, the endpoints inside the VoIP network are, an analogue phone (attached to an analogue port over a gateway) as well as a private branch exchange (PBX) (linked to a digital port over a different gateway). Because neither of those endpoints natively speaks IP, the topology is recognized as a VoIP network. With VoIP, a Gateway and other device covers the conversion of Voice into IP packets.
The bottom portion of the drawings shows an IP phone, which does natively communicate using IP. The IP phone registers having a call manager or call processing server, helping to make call routing decisions on behalf of the IP phone. Therefore, underneath topology within the figure is known as an IP telephony network. With IP telephony the VoIP telephone systems be careful on the conversion of Voice into IP packets. Realize, however, that some literature might use the terms VoIP and IP telephony interchangeably.
IP telephony replaces traditional phones with VoIP telephone systems and uses call processing software, normally by using an appliance, server or cloud based for call control and signalling, rather than PBXs. The IP Phone itself performs voice-to-IP conversion, and voice enabled routers aren't required inside the enterprise network. If a link with the PSTN is required, a voice enabled router or another gateway must be added where calls are given to the PSTN. IP telephony identifies cost-effective communication services, including voice, fax and voice messaging applications, transported through packet-switched IP network rather than the circuit switched PSTN.
