Believe it or not, we didn’t always carry supercomputers around in our pockets. Smartphones and widespread internet connectivity are relatively recent innovations. The official birthday of the internet was January 1, 1983, and the world’s first smartphone was released in 1994 by IBM. Since then, we’ve come a long way, building upon traditional phone systems to create the modern phone networks we know and love today. 

But those old phone systems have been showing their age for a while now, and newer, more powerful and flexible alternatives now exist.

In this post, we’ll define POTS (plain old telephone service) and explain how it’s kept our world connected since the late 1800s. By the end, you’ll be able to make the best decision for your business phone system by choosing a modern business phone alternative to POTS lines.

What is a POTS line?

POTS is an acronym used to describe the analog telephone service the U.S. has used for over 100 years. Better known as “plain old telephone service,” the system transmits signals via copper wires. You may have also heard it referred to as the public switched telephone network (PSTN), which is a fancier term for the same system.

POTS is based on Alexander Graham Bell’s phone system, the first in the world of its kind. It makes use of copper twisted pair wires to connect homes and businesses to central control rooms. In fact, POTS used to stand for “post office telephone service,” because post office operators were the ones who connected callers from a switchboard.

After making the transition away from operators, the switching process was automated for calls made over POTS lines. The newer, centralized system was better adapted to handling high call volumes and managing calls across long distances. But it was still lacking in features. At first, there was no way to block numbers, and call forwarding was still just an idea.

As technology advanced, features like call waiting, voicemail, and caller ID were integrated into the POTS system. Modems and fax machines also used POTS lines to convey digital information. This analog telephone system is still the basis for most of our modern telecommunications.

How do POTS lines work?

When you make a call through POTS, the system establishes a connection between point A (where you are) and point B (where your intended call recipient is). Because the POTS lines system is completely analog, it uses copper wires to connect between the two locations. Depending on where you’re calling from, your call may need to be routed through several central offices to reach its final destination.

Once you’ve placed your call, the audio is converted from sound waves into electrical analog signals. These signals are carried by the copper wires to the receiver’s end. Then, they’re changed back into sound waves so that the receiver can understand you. 

One of the downsides of copper lines is that they can create noise interference. The signals they transmit also grow weaker with distance, meaning that amplification may be necessary to deliver the signals from caller to receiver.

What is the best alternative to POTS?

The best alternative to POTS is VoIP. But it’s not the only alternative, so let’s explore some other options and then look at what VoIP wins easily.

While POTS lines have been used for decades to manage call routing for both personal and business purposes, things are changing fast. The technology is becoming outdated, and maintenance costs are soaring. That leaves business and personal users seeking more modern, convenient solutions to traditional plain old telephone service. 

One alternative is an integrated services digital network (ISDN), which transmits digital signals through analog lines. Digital subscriber lines (DSLs) are another option. DSL makes use of existing copper lines and multiple transmission frequencies to simultaneously send analog voice audio and digital information. However, a DSL connection may require a filter to prevent digital “leaks,” and both solutions need physical wires connecting them to service.

Enter Voice over Internet Protocol (VoIP) phone systems. Rather than converting sound waves into electrical analog signals like POTS lines do, your VoIP works by converting sound waves into digital signals. These signals are transmitted via the internet rather than traditional telephone lines.

Hands-down the best alternative to POTS lines, VoIP systems offer expanded user features, along with flexibility that simply wasn’t possible with analog lines. VoIP allows you to place and receive calls from any internet-enabled device. You can also tap into an LTE data connection if you experience power outages or poor connections.

Why choose a VoIP service provider?

Using a landline phone system supported by POTS probably isn’t the best business decision you can make in the 21st century. VoIP technology trumps POTS lines for several reasons. 

Cost-effectiveness

The rising costs of POTS line maintenance and service means that the technology will soon become cost prohibitive. The POTS pricing model is also outdated, with users having to pay extra for setup and each additional feature. In the U.S., major telecom companies are lobbying the FCC to eliminate legacy POTS systems, which have fewer subscribers with each passing year. Telecom giant AT&T, for instance, has raised phone prices by 153% over the past decade. All the while, service quality has deteriorated, as has customer satisfaction.

Better call quality

Because VoIP lines make use of your broadband internet connection rather than copper wires, you won’t have to worry about a decline in call quality. If you’re switching from a POTS legacy system, you should expect clearer audio, as long as your internet service is up to the task (you can verify your bandwidth strength with a simple VoIP speed test).

Expanded features

Apart from better call quality, you’ll enjoy access to features that simply aren’t compatible with POTS lines, like Do Not Disturb mode, texting, and shared phone numbers. You can also forward calls to and from any device, minimizing missed calls and simplifying your life. Some VoIP providers even offer third-party integrations, so you can connect your phone system with business operations and customer relationship management (CRM) software.

Easy setup and maintenance

Every business needs an efficient system to communicate internally and with clients. POTS service can be difficult to install and maintain, since it requires physical wires running to your place of business. That also makes it incompatible with remote work, which is growing in popularity.
