VoIP (Voice over Internet Protocol), often known as IP Telephony or Internet Calling, is a low-cost alternative to traditional PSTN phone calls (Public Switched Telephone Network).
How does VoIP Work?
VoIP works by converting ordinary analog audio signals into digital data that can be sent over the internet via the IP Protocol.
Surprisingly, there isn’t just one way to make a VoIP call; instead, there are three different types of VoIP services available today. These are the following:
ATA: This is the most basic and widely used method of VoIP communication. You may connect a conventional phone to your computer or internet connection for usage with VoIP by utilizing an ATA (Analog Telephone Adaptor). An analog to digital converter (ATA) converts the analog signal from your phone into digital data that may be sent over the internet.
It’s really simple to use, which is why it’s been widely accepted around the world.
IP Phones: An IP phone is a specialized phone that resembles a regular phone and has the same handset, cradle, and buttons as a regular phone, but instead of a standard RJ-11 phone connector, IP phones feature an RJ-45 Ethernet connector. IP phones connect directly to your router and come equipped with all of the required hardware and software to handle an IP call.
Computer-to-Computer: Of the three basic methods, this would be the most straightforward way to use VoIP. Computer-to-computer VoIP calls are made between computers using software installed on your computer or device, a microphone and speakers (or headset), and an internet connection. This VoIP framework is used by popular providers like Skype to provide their services.
What are the advantages of VoIP services?
Using VoIP over traditional phone services has a number of advantages. These are some of them:
Cost: VoIP is a simple approach for many organizations to reduce communication costs. The beauty of VoIP is that it makes use of existing infrastructure without incurring extra costs. In many circumstances, VoIP services can be utilized for free on computers or devices with the appropriate software, as well as on mobile and landline phones in some cases. When the expenses of international business calls are factored in, this becomes an easy choice for business owners all around the world.
Easy setup, installation, and maintenance: Another advantage of VoIP services is their simplicity in terms of installation, configuration, and maintenance. Because the physical setup is so easy, you usually don’t need an engineer to set it up. Once the system is up and running, using the system manufacturer’s portal or software, it’s simple to customize and personalize the system for each user, if you prefer a professional to setup your VoIP, you can view our VoIP options here.
Scalability: It’s not always easy to foresee how many phones you’ll need in the coming year, and if you’re using a traditional phone system, you’ll have to guess carefully to avoid wasting money on lines you won’t use.
VoIP systems eliminate all of this. When you use VoIP for your business, you may add a line as soon as you hire a new employee, and you can easily reassign or remove the line when that employee quits. You always have the appropriate amount of phone lines.
What are the disadvantages of VoIP services?
There are a few drawbacks to using VoIP services over PSTN, however they are minor. They are as follows:
Power supply: A normal phone system relies on phantom power from the central office, which is sent over the phone line. Your phone (unless it’s a cordless) will continue to work even if your electricity goes off. When it comes to VoIP, if you don’t have power, you don’t have a phone. For VoIP to work, a reliable power source must be established.
Because VoIP relies on a stable internet connection, it is prone to the same vulnerabilities that plague traditional home broadband services. Latency, jitter, and packet loss are all variables that impact call quality. Transmission failures can cause phone conversations to become distorted, garbled, or lost.
VoIP is here and it is here to stay
VoIP, despite being a relatively new technology, has already gained widespread acceptance around the world. There are still many improvements that may be done and are expected to be introduced in the next years.
If they haven’t already, operators around the world are providing VoIP services, and several large operators have begun to transition to a fully digital service.
VoIP is clearly here to stay, and it will continue to grow in popularity around the world.
