A Complete Guide On VoIP And How Voip Works With Top Technical VoIP Terms
The use of VoIP (Voice over Internet Protocol) has increased significantly in the past few years, especially because everyone is searching for ways to save money. The costs involved with a telephone bill have led many people across the country to ditch their landlines and rely exclusively on their cell phones. However, if you know how to use a VoIP service, you can save even more money, so keep reading to find out all about it.
In this article, we will disucss
Voice Over Internet Protocol or simply VoIP for short is a protocol that allows the transmission of voice packets over the internet. There are many use cases for this technology including low-cost long-distance telephone service, online phone systems, and even streaming music.
Now I know what you’re thinking, “I’ve been using Spotify for my music streaming needs since 2012!” And while that may be true it’s not really an example of real-time audio data being transmitted via a network. That’s because Spotify uses a form of lossy compression to reduce its audio stream’s file size so as to save bandwidth on your mobile device. This means that instead of transmitting the audio data in real-time it is being sent once and then Spotify fetches the audio stream itself.
However, with VoIP technologies, there is no compression for file size, which means that you are able to hear the original transmitted audio in all of its uncompressed glory when using services like Skype or Google Hangouts.
Now you may ask, “What’s the catch?” Well, because lossless streaming requires more bandwidth than lossy streaming it can be harder to find an internet service provider (ISP) that offers this type of connection. This is why many people turn to companies like Sonic.net for their ISP needs in order to enjoy quality voice-over-Internet Protocol calls on a reliable connection every day of the week!
When you make a call using a VoIP service, your voice is converted into digital information and sent over the network to the person you are calling. The signal usually requires translation from digital information back to analog sound before it can be received by the other party on the call.
In recent years, many businesses have been switching from traditional landline telephones to Voice over Internet Protocol systems. This switch has been driven partially by cost savings — VoIP services are typically less expensive than standard phone service — but also by increased flexibility and productivity gains.

🏆 How VoIP Works?
VoIP is a modern technology that operates through a broadband connection and allows you to make calls from one point to another over the internet. The acronym “VoIP” stands for Voice Over Internet Protocol, which means that it converts regular telephone calls into digital data packets and relays them over the internet.
First of all, before we can get started with how does VoIP works, we need to understand what protocols are. This will help us become familiarized with the jargon used when referring to VoIP and will give us a better understanding of how it functions.
Internet Protocol (IP) is the standard language that the internet uses. One of its central principles is being able to transport data packets from one location to another, without being too concerned about their ultimate destinations. This means that IP doesn’t care if you are sending an email or downloading a video – it will get them where they need to go. The methods used by IP in order to accomplish this task are called protocols.
There are two kinds of protocols: Connection-oriented and Connectionless protocols. Connection-oriented protocols establish a link between the source and destination points before exchanging any information, while connectionless protocols send out individual data packages without establishing links ahead of time. IP is considered a connectionless protocol.
The simultaneous use of IP and protocols that operate connection fully is what enables us to establish internet connections. For example, the Transmission Control Protocol (TCP) establishes end-to-end communication between two devices through three stages:
STEP 1: Synchronization
STEP 2: Connection
STEP 3: Data transfer.
Each of these stages may be completed by means of different protocols, like the File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), or Gopher. This complicated network structure can get confusing for those who are new to VoIP jargon, so it’s important not to get too overwhelmed if you hear mention made of TCP/IP. Understanding this complex network structure will help you learn how does VoIP works in the simplest way possible.
Once we have established what the difference is between connection-oriented and connectionless protocols, we can now move on to how does VoIP works. For this task, there are three main components that are essential to look at Codecs, Routers, and Analog-to-digital converters.
✅ Codecs are responsible for encoding speech signals into electronic data packets, which means they turn the sound of your voice into digital form. This process of changing analog signals into digital ones is called sampling. Sampling makes it possible to encode voice in different ways so more people will be able to understand it more clearly. It doesn’t matter if you have a deep or high-pitched voice – using VoIP gives you more flexibility with how you choose to communicate. The process of decoding a signal is called a codec, which means that it takes a digital voice and turns it into an analog. The most common way to encode speech electronically is by using pulse-code modulation (PCM).
Codecs are active components of VoIP technologies and come in different shapes and sizes. For example, you will find among them codecs specifically made for wireless devices like cell phones or mobile applications on your computer. In these cases, the audio data packets have to contend with limited bandwidths, while others have more bandwidth available to them because they must only deal with desktop users over traditional landline connections. This variance in connection types dictates which type of codec needs to be used for transmitting your voice.
✅ Routers are necessary for transferring encoded voice packets from one source to another. They accomplish this task by using IP as a way of moving the packets from your computer to other terminals on the internet. In order to do so, routers must find a path that will enable transmission between computers, which involves going through any number of network locations until it reaches its intended destination.
Routers communicate with each other in terms of layers and protocols, sometimes having a difficult time making sense of what they receive from other routers. This information is extremely vital because it allows them to determine where traffic needs to be forwarded or redirected. Routers also have an important function when it comes to quality control – they regulate data flow by monitoring activities like denial-of-service (DOS) attacks.
✅ Another important aspect of how does VOIP works is an analog-to-digital converter. The A/D converter takes sound signals from the microphone and turns them into electronic packets that can be interpreted by routers or codecs. This means that these components require A/D converters in order to function properly, which allows you to speak on your phone, computer, or other VoIP devices. When calls are transmitted over internet lines, bandwidth becomes a concern because it’s necessary for processing information in real-time. You would think there would be no place for low-bit rate audio codecs when using the internet but this isn’t always the case since they will vary depending on what devices are being used (mobile phones vs landlines).
Some of the most popular codecs are G.711, G.729, and iLBC. These encode speech in different ways depending on how they were designed – for example, one might produce better quality sound than another but use more bandwidth. Codecs vary when it comes to what they do with bits – some don’t change any data that is fed into them while others discard redundant ones or compress smaller segments into bigger ones in order to save space.
Codecs also convert analog signals in one direction only because this allows them to be used within VoIP networks without affecting voice quality by repeating the sampling process over again. This would mean that you’d have someone speaking on your phone or computer twice since each signal has to travel through both the sending and receiving codecs.
The entire process of how VoIP works can be broken down into smaller parts in order to get a better idea of what goes on behind the scenes. This enables you to make educated choices about which hardware or software you want to use when communicating with other people over your internet connection.
In Short, A VoIP phone works according to the following steps:
- When a VoIP phone receives the digital data from another device, it splits the data into information packets and puts a destination address on each packet.
- The converted data is then sent over your broadband line to your router.
- Once the router has received the data, it finds the shortest path to its destination. The packet might pass through multiple routers in order to optimize the final route.
- The packet is then received at the destination.
- The receiving VoIP phone then uses the addresses for each packet to put the packets in the correct order.
- The VoIP user then receives the data as recognizable speech.
🏆 Top Technical VoIP Terms
There is a bit of a learning curve when it comes to VoIP. With new technologies and buzzwords always emerging onto the scene, those getting started with VoIP might find themselves with more questions than answers. That’s why we’ve created this list of 10 of the most common VoIP terms that business professionals should know.
🔥 Bandwidth – The bandwidth of a network connection determines how quickly data can be sent between devices on the network, so it’s important to have enough of this essential resource for all connected devices. This is usually measured in bits per second or megabits per second (Mbps).
🔥 Codecs – A codec is any device or program that compresses and/or decompresses information, such as an audio file. This is necessary to save space when sending data over a network. There are two types of codecs: lossy and lossless. A “codec” can also refer to the process of compression and decompression.
🔥 DSL – DSL stands for digital subscriber line or a type of internet connection that uses existing telephone lines to provide fast data transfers at affordable prices.
🔥 IP – Stands for Internet Protocol which is the way that computers send and receive information across the Internet. This is essentially how VoIP devices communicate with each other over the network.
🔥 IVR – Short for Interactive Voice Response, an IVR system allows users to interact with a device by pressing buttons in order to navigate through voice menus.
🔥 Latency – This term describes the amount of time it takes for information to be sent from one point to another. High latency can result in audio delay or echo during a VoIP call, which is why it’s important to keep this number as low as possible.
🔥 PBX – Short for Private Branch Exchange, a PBX is a phone system that connects all internal voice and data lines within an organization, allowing employees to make telephone calls much more efficiently.
🔥 SIP Trunking – Also known as Session Initiation Protocol, SIP Trunking is a technology that allows an office to use data lines for phone calls instead of traditional telephone lines.
🔥 Softphone – A software-based telephone which can be used on desktops or mobile devices. It’s essentially the same as using a regular phone with VoIP features, but it works over the internet instead of through a traditional phone line.
🔥 VoIP – Short for Voice over Internet Protocol, which is very much exactly what it sounds like: the transmission of sound information using an IP network.
🏆 What Are The Advantages Of Using VoIP?
In recent years, VoIP usage has been growing due to its numerous advantages. One of the most common ways to use VoIP is through a broadband connection. However, if your organization uses a dial-up modem or does not have internet access, you can still take advantage of these benefits with a software phone.
Additionally, conference calls can be used by up to four people at once including yourself. Since you’ll be able to see who is on the call in real-time via an application like Skype, you’ll never have to worry about being on hold. This allows businesses to communicate more effectively.
🏆 How Does VoIP Work With Different Devices?
Having a home telephone system is very common around the world. However, we’ve seen that IP technologies are replacing conventional communication systems and telephony is not an exception. The technology of Voice over IP (VoIP), has gained popularity in recent years and it provides users with lots of money-saving benefits and opportunities to communicate with each other from any place on earth using the Internet connection. This section of the article will show how VoIP works when different devices are used.
👉 Analogue Telephone Adapter: In order to use VoIP you need a broadband internet connection and an analog telephone adapter (ATA). It converts your analog phone line into a digital signal which can be transferred through the Internet network. After this conversion occurs, it’s time to connect your phone to the device.
👉 VoIP Handset: In case you want a phone working as a VoIP client then an analog telephone adapter is not necessary for this purpose. You can use a special digital handset that will connect directly to your internet cable or wireless router. Connect it and you will be able to make free calls. There are so many models of this type of phone on the market, but some of them have additional functions such as calendar, address book, and other useful applications which make life easier.
👉 Smart-Phones: If you have a smartphone, it already includes all the hardware elements needed for VoIP connection, including Wi-Fi compatibility and apps required for video calling. All you need to do is download an app (SIP client) for VoIP calling.
👉 Computers and Laptops: If you want to make video calls or conference with your co-workers, you can use your computer or laptop for this purpose. It’s really easy because all the hardware elements needed are built-in inside modern devices. For a better audio connection, an external microphone is useful but it is not necessary if you just need to chat with friends via video calling.
I hope, now you have a basic idea about VoIP. So if you want to shift to VOIP and search for the best VOIP service providers, then here are my top picks.
Conclusion
VOIP got very popular lately due to the fact that it is both cheaper and easier (due to the internet infrastructure and wide availability of IP-capable devices) than traditional telephony services. No wonder then, that many people use VoIP as an alternative for their regular phone service.
