VOIP

This article contains excellent information about the IP voice protocol.

Voice over Internet Protocol [VoIP] technology is the wave of the future of telephone communications over the Internet. VoIP has several advantages over circuit switching technology used by local telephone companies. Circuit switching technology uses permanent technology. The connection between the caller and the callee requires a lot of bandwidth per call.

This type of technology can only carry certain types of calls, such as phone to phone. Moreover, hardware circuit switched networks that require efficient operation are very expensive, primarily because voice and data services must be supported on different lines. Therefore, each service requires separate hardware to accommodate the voice and data types of the traffic. Undoubtedly, your local telephone company will pass on the cost of building and maintaining a circuit-switched network to you, the consumer. Unfortunately, this is equivalent to a higher rate for your phone service.

VoIP - how does it work?

VoIP technology refers to the use of the Internet Protocol [IP] to call the travel network over the telephone. This means that calls are delivered over the Internet or a privately managed data network that uses IP to send calls from one location to another. Thus, when a call is delivered over the Internet or a data network, the voice stream is broken down into packets, compressed and sent to its final destination over several different routes.

This is where circuit switching technology differs from IP technology because circuit switching technology uses permanent technology. Connect the entire phone. Once the call arrives at the called party, the voice stream packet is reassembled, decompressed, and switched back to the voice stream by several hardware and software elements, depending on the final destination of the call. The type of software and hardware required to initiate and end a phone call depends on where the call originated, such as a PC, phone or integrated access device [IAD], and whether the call will be completed on the PC, by phone, or by IAD.

Advantages of VoIP

Here is a list of the many benefits of using VoIP:

• Voice and data can be sent over the same line.

• The number of calls that can be made on these lines is eight, not in a circuit-switched environment.

· The sound quality is very good.

Reduce operating costs by reducing hardware requirements and a more efficient network infrastructure.

• The lower cost structure makes the rate lower than traditional telephone companies.

• Communicate with each other using different devices.
