Difference Between Landline and VOIP

We all wish to keep in touch with relatives, acquaintances, classmates, and co-workers who live in various neighborhoods, cities, towns, or countries. People were unable to communicate with one another without the existence of technology. If anybody ever communicated, it was with the help of letters. Fire and smoke signals were some of the methods used to communicate with others around.

Communication became a little easier with the invention of landlines. People went to the nearest Subscriber trunk dialing (STD) and international subscriber dialing (ISD) to make a call to pass on important information to their friends and family. Many years later, VOIP was introduced, making communication even simpler and less expensive.

Landline vs VOIP

The main difference between landline and VOIP phones is that landline phones have solid dialers and receivers. They involve analog technology for making a call to our people. However, VOIP (voice over internet protocol) is a technology, not any device that allows us to make our personal and professional calls over the internet.

A fixed line connected to a landline comes from the local telephone exchange. Landline consists essentially of a rectangular or spherical dialer with a single receiver that converts sound energy into electronic energy. People might phone different parts of the country for varying costs (national or international). The landline’s copper wires worked on the optical fibers.

VOIP stands for voice over internet protocol, which allows users to make phone calls over the internet. We may use this technology to make free international calls by only paying for an internet connection. Digital signals or discrete signals are used. A mobile phone or tablet is required to make a phone call.

What is Landline?

Landlines are a type of telecommunication service that allows people to communicate with one another to share vital information. A dialer (which aids in number dialing) and a receiver (which assists in speaking to the person who is on another side) make up a landline.

The landline receiver has a diaphragm and a transmitter. Landlines were only accessible at STD (local calls) and ISD (international calls) stores when this technology was new. When time passed, almost every home in ancient times had a landline connection.

Hearing other people’s voices is aided by the diaphragm. On the other hand, the transmitter converts sound waves into electrical waves. The cost of calling loved ones on a landline was decided by the region and the amount of time spent conversing.

If people made national calls, charges were less as compared to the calls people made overseas. The receivers were fixed on older landlines. With time, however, codeless receivers became available.

This technology is not portable due to the fixed-line that runs from the telephone exchange to the intended destination. As a result, because it is based on optical fiber technology (signal transfer via vibrations and pulses), no internet is necessary to utilize a landline at home.

What is VOIP?

Voice over internet protocol is abbreviated as VOIP. It signifies the usage of internet service to communicate with loved ones and colleagues. Marian Croak, an African American lady, is the one who brought up this internet-based technology.

The internet became available in 1983 when people could only interact with each other using landlines. People connected better with other people across the world as the network became available. After then, in 1995, the invention of VOIP occurred.

While calling, this technology converts analog signals to digital signals. To use it, you’ll need any one of the gadgets (smartphone, a laptop, a computer, or a tablet) with excellent earphones.

Many applications, such as Skype and WeChat, were created employing VOIP technology to allow users to make international calls without paying a penny for the call. People only pay for internet packages that can be purchased for a specific number of days, weeks, months, or years. It means it saves a lot of money.

Many famous applications, such as WhatsApp, Facebook, and others, were later built using the voice over internet protocol, which allows for voice and video calling to people. This service is also helpful for doing business online by doing video conferences at a professional level.

Main Differences Between Landline and VOIP

  1. In the nineteenth century, Alexander Graham Bell (a Scottish engineer) introduced the technology, the landline. Marian Croak, an engineer, was the first to develop VOIP in the late twentieth century.
  2. Landlines are used without an internet connection because the internet came later than this technology. VOIP, on the other hand, is an internet-based technology.
  3. Landline technology is based on analog signals(which might cause disturbance while talking). However, the voice-over-internet protocol is based on digital signals.
  4. Calls made over the phone are more expensive than calls made using voice-over-internet protocol (VOIP) technology.
  5. A device that consists of a dialer and a receiver is required to use landline service. However, you need a smartphone or similar device that has an internet pack to use VOIP.


We benefit from both landlines and VOIP. We would be unable to communicate with our families and friends while away from our home region if such technologies did not exist. We’d have been less aware of one another. These technologies are beneficial to everyone. People were relieved when landlines were introduced because they could communicate what was going on in their lives to loved ones much more conveniently than they could with letters and pigeons.

They were able to hear their people (loved ones). However, because VOIP technology is more cost-effective and accurate than landlines, we can communicate more effectively. Furthermore, several VOIP software packages are available on the market that allows us to see persons who are thousands of miles afar while conversing.
