a) Uses a public switched telephone network, b) Skype is an example of VoIP software, c) Uses a slow dial-up connection, d) All of the above. Which of the following is true of VoIP?
Voice over Internet Protocol, or VoIP, is a type of communication technology (including hardware and software) that allows you to make phone calls over an internet connection, rather than a traditional analog phone line that uses wires or optical fibers to make a connection. VoIP is also known as internet connections, IP or internet telephony.
VoIP is transmitted by various methods, including traditional telephones, smartphone applications, computer software or specific VoIP-enabled telephones.
How does VoIP work?
VoIP involves splitting voice into digital packages, such as electronic envelopes, and sending the packages as data to the recipient over the Internet.
VoIP is available in various systems, making it available to anyone with a reliable Internet connection. You can make VoIP calls over:
- Telephone and VoIP adapter. With the adapter, you can use a regular landline phone to make calls over the Internet. The adapters are connected to a telephone wall jack or directly to a router.
- Computer (i.e., “Program Phone”). Many programs or applications are available that allow you to make voice calls over the Internet, including Skype, Google Voice and Apple FaceTime.
- Smartphone. Using a smartphone, you can download applications such as Google Voice or Skype that allow you to make internet calls.
- Dedicated VoIP phone. They look like traditional analog telephones, but connect directly to the computer network, not the phone line.
Unfortunately, VoIP also has some disadvantages. The bottom line is that you need to have a good internet connection, otherwise you will have constant problems with voice quality and intermittent connections. One thing that can’t be prevented is a delay (one second of silence during calls), which is a mistake when using UDP VoIP. Because internet and telephone traffic goes through the same cables, they both have the same bandwidth, which means that extensive use has a large impact on the quality of connections. Secondly, if your Internet is turned off, VoIP will also be turned off. And, as with any internet-connected device, the cloud phone system can be hacked too.
However, if you choose a reliable VoIP provider and use the system with great care, all of the above problems can be easily prevented and you can enjoy high-quality VoIP service for as long as you want.
