What is a POTS line?
A POTS line is a Plain Old Telephone Service landline.
POTS is the original telephony system that has been linking everyone together since the 1870s when inventor Alexander Graham Bell demonstrated electromagnetic telephony for the first time.
The main thing to understand about a POTS telephone line is that it depends on a physical connection. A truly massive network of copper lines carries signals, ultimately, from one handset to another.
This multi-step process becomes even more complex with international calls, contributing to the voice quality issues you may notice on long-distance POTS calls.
A key consideration with a POTS line is that we are dealing with an analog representation of a voice. Unlike the digital approach, there is no conversion to data here. It’s a straight transfer of soundwave to electrical signal, both of which forms are subject to interference and degradation over distance.
What are POTS lines used for?
POTS lines are still used for a variety of applications, particularly in environments where reliability is important and, in the past, digital options weren’t trusted to get the job done. Here are some examples:
- Voice communication: Traditional landline phones in homes and businesses can still use POTS lines, but this is becoming rarer.
- Fax machines: Many businesses still rely on fax machines connected through POTS lines to send and receive important documents securely. Once again, though, the rise of reliable online fax solutions is making this less common.
- Fire alarm panels: When a fire alarm is triggered, POTS lines are used to connect fire alarm systems to monitoring centers, ensuring a prompt response to fire emergencies.
- Elevator phones: Many elevators are equipped with emergency call phones that use POTS lines to ensure a stable connection in case someone needs assistance.
- Safety systems: Security systems often use POTS lines to transmit alarm signals to monitoring centers, ensuring reliable connectivity in case of emergencies.
- Credit card terminals: Retail and point-of-sale systems frequently use POTS lines for processing credit card transactions, especially in areas with unreliable internet service.
- Emergency services: POTS lines are crucial for emergency phone services due to their reliability, even during power outages, providing a dependable way to contact emergency responders.
- Medical alert systems: Personal emergency response systems (PERS) for the elderly or disabled often use POTS lines to connect to monitoring centers, ensuring help is always available.
- Public pay phones: Although less common now, public pay phones still utilize POTS lines for providing accessible communication options in public areas.
RingCentral POTS Replacement: The best of your POTS line replacement options
POTS telephone lines have pretty much reached the end of the road, developmentally speaking. There’s nowhere else for them to go. They’re not going to provide any more features than they do already, making them a good deal less practical for businesses with developing sets of needs.
There’s another big issue to bear in mind, too. In various parts of the world, POTS is being phased out. It’s been found that maintaining these old copper networks consumes too much time and materials to make the process sustainable. The FCC is also no longer requiring carriers to support POTS lines.
That means you need to find a way to replace any POTS phone service or related system, and RingCentral has you covered.

POTS line FAQs
- Businesses and consumers are increasingly moving away from POTS in telecommunication, in favor of digital systems based on VoIP technology. Some continuing uses of POTS lines, however, include in systems such as fire alarms, elevator emergency phones, and medical alert systems.
- Scalability: VoIP-based systems are far more easily scalable than a POTS telephone service. Being software-based, VoIP systems let you add new users, lines, features, and more with just a few clicks. To scale a POTS landline phone service will often require installation of new physical infrastructure.
- Mobility: A POTS line is a fully physical entity, so if there’s not one near where your employee is, then there’s not going to be a service. On the other hand, a VoIP system is available to all your remote employees on their mobile devices.
- Cost: Here’s an interesting point in the POTS line vs VoIP debate. While, you might think that the older landline technology would be less expensive than VoIP, since it’s been around longer, that’s not always true. In fact, maintaining the traditional copper wire networks for landlines is becoming more and more expensive.
- Features: POTS can give you calls, some call management features, and faxes, and that’s often pretty much it. A VoIP phone system can offer a vast range of features, from straightforward calls to auto attendants and IVR. Plus, some are part of more holistic unified communications systems that also encompass digital communications channels.
- The caller dials a number, which is translated into electrical signals and transmitted down a cable to a receiving terminal.
- The signals then go via an aerial cable to a phone company unit, within which automated procedures direct the call in the right direction. This might be to a central office or a tandem office, depending on how the company is set up and where the destination number might be located.
- Once the signals get to the relevant office, they are directed to a terminal for further assessment.
- At this point, the appropriate local line is selected, and the intended recipient’s handset is alerted. This is how calls get routed.
- Once the connection is established, the caller can commence communication by speaking into their handset. The soundwaves thus produced are converted into electrical signals.
- The signals motor their way from one handset to the other, via the connection that’s been set up as above. When they get to the receiving unit, they are converted back into soundwaves, in other words, words.
