What is VoIP,  - Voice Over Internet Protocol. How does a VoIP phone work
VoIP (Voice over Internet Protocol) is a technology that enables voice communication over the internet rather than traditional phone lines. It converts audio signals into digital data packets, which are transmitted via the internet. VoIP allows for cost-effective calls, often at lower rates than landlines or mobile phones, and offers additional features like video calling, voicemail, and conferencing. Popular applications of VoIP include Skype, WhatsApp, and Zoom, making it a widely used method for personal and business communication.
How does VoIP work?
When you make a call using an analogue line, it establishes a dedicated connection between the two parties for the duration of the call. Voice over IP uses Internet Protocol, a necessary building block of the Internet. IP telephony is a great invention of the century-old telecommunication system.
How do VoIP Phones work?
When you apply VoIP to generate phone calls above the Internet, your voice has to be encoded in digital data, and this digital data has to be re-coded into tone signals at the other end of the call. This coding process is achieved through Codecs, which is short. The codecs ensure that the data is compressed, which means it moves faster and, as a result, the quality of the call is better.

Why would someone have a VoIP phone?
New technology is always developed to fix the flaws of the drawback, but sometimes it also has its failures. 
VoIP Advantages
Low Cost
How VoIP Works
Since VoIP is working with your internet connection, a traditional phone line is not required. 
Ease of Accessibility
One of the biggest benefits of VoIP service is the ability to call at any time whenever you have a decent internet connection. 

How does a VoIP phone work
Unlike a PBX (Private Box Exchange), VoIP networks are much softer. When you choose a VoIP phone service provider, you will be sent a converter to allow regular phones to use VoIP phone service. Your phone number is programmed in the converter. This means you can take your phone converter and phone number and use it wherever you travel in the world, as long as you have a high-speed internet connection.
Voice Quality
If you have a steadfast internet connection with superior bandwidth, you should familiarity with sound quality that is corresponding to a traditional phone connection, if not better. 
VoIP Disadvantages
No service during a power outage
During a power outage, the current source provided by the phone line is kept in regular phone service. This is not possible with an IP phone, so when the power goes out, there is no VoIP phone service. 
Reliable Internet Connection Required
Your VoIP service is just as high-quality as your internet connection. If your network bandwidth is low, the service will suffer. VoIP does not use as much bandwidth as you might expect. 
Latency
Due to bandwidth requirements, some  voice over ip calls may be delayed, delayed, or disappear altogether. This is because an effective call requires time to re-assemble the information packet. 

Is VoIP Reliable?
In the early days of voice over IP, calls fell, and delays were common. As Internet bandwidth has increased, the quality of VoIP calls has improved dramatically. VoIP calls are more stable and clear than landline phones.
