VoIP (pronounced “Voyp”) stands for “Voice over Internet Protocol” and to make a long story short—it allows you to make calls through your home internet connection. When you make a call with your VoIP system, your voice is converted into data and transmitted to the caller at the other end in the form of high-quality audio. The sound and connection typically are seamless enough to where you won’t even know the call you’ve received is from a VoIP line. 
The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 gigabit per second) Local area network (LAN) using existing home wiring (power lines, phone lines and coaxial cables). G.hn provides QoS by means of Contention-Free Transmission Opportunities (CFTXOPs) which are allocated to flows (such as a VoIP call) which require QoS and which have negotiated a contract with the network controllers.

At the VoIP level, a phone or gateway may identify itself with a Session Initiation Protocol (SIP) registrar by its account credentials. In such cases, the Internet telephony service provider (ITSP) knows only that a particular user's equipment is active. Service providers often provide emergency response services by agreement with the user who registers a physical location and agrees that emergency services are provided to that address only if an emergency number is called from the IP device.

One important advanced feature that's ubiquitous in the world of business VoIP services, and quickly growing in the residential market, is the softphone app. Imagine a piece of software that simply uses the network connection, speakers, and microphone of your computing device to turn that device into a phone. If that softphone is attached to your VoIP account, that software will ring whenever your home phone does and when you place calls on it, those calls will register as coming from your home phone number. Just by installing the software you'' be able to immediately place and receive voice calls over your home phone account on your PC, your Apple iPad, or even your smartphone. That last one is a gotcha, however.
Not every internet connection is VoIP ready, so before you sign up, make sure that your line will provide you with the level of VoIP speed and service you need. You can easily find resources online for checking the speed and call quality of your connection. The quality of your connection can potentially impact the clarity of your calls, so pay close attention. 
The only area where a landline offers something VoIP phones can't is that they're more disaster resistant. Lost power to your house and your landline phone will keep on working. But if the power drops to your home's internet router, our VoIP phone goes dark, too. However, this limitation is less crippling these days as most people have a smartphone of some kind backing up their home phone. That phone will keep working in the event of a power outage, which means you can still make emergency calls. And if you've opted for a mobile client on your home VoIP account, you can even make those calls using your home phone number rather than your mobile number if you prefer.
Similar to Ooma's residential service (below), AXvoice deploys its home VoIP with the help of an appliance, appropriately called the AXvoice Device, which sits between your home's phones and your Internet router.

Work When & Where You Want – One very popular and common feature of business VoIP systems is called “find me/follow me.” Instead of having separate numbers for your office, cell phone, and home office, you have one “virtual extension.” You can program the virtual business phone service to ring all of your extensions simultaneously, or in a specific order, and you decide how to handle a missed call. You decide if a call should go to your voicemail, or to another extension. When you make a call using your cloud phone system, the receiving caller ID will show your business phone number, regardless of which device you are calling from.
SIP is built to work on a peer-to-peer (meaning endpoint to endpoint) basis. Those two points are called the "user-agent client" and the "user-agent server." Remember that those points can be swapped, so that in SIP, the endpoint making the call is the user-agent client initiating the traffic and endpoint receiving the call is the user-agent server receiving the call.
Fortunately, there are several dedicated residential VoIP providers who offer nationwide service, usually with worldwide calling plans. With one of these you should be offered at least four core features. Those include caller ID, voicemail hosted by the provider (meaning you don't need an answering machine), call waiting (essentially a one-line hold), 911 support (sometimes called "E911"), and three-way calling allowing you to reach out to a third participant in any phone conversation. There will likely be a slew of other features available, but they'll differ across quality providers while these four should always be available. Most of these will work in a two-step process:
Network routers on high volume traffic links may introduce latency that exceeds permissible thresholds for VoIP. Excessive load on a link can cause congestion and associated queueing delays and packet loss. This signals a transport protocol like TCP to reduce its transmission rate to alleviate the congestion. But VoIP usually uses UDP not TCP because recovering from congestion through retransmission usually entails too much latency.[16] So QoS mechanisms can avoid the undesirable loss of VoIP packets by immediately transmitting them ahead of any queued bulk traffic on the same link, even when the link is congested by bulk traffic.
Residential VoIP service providers are the most popular choice for home phone services in 2020.
