Is VoIP better than landlines? What advantages does a traditional analog phone have over an IP phone? It's crucial to understand these differences when choosing the right phone system.
You're likely familiar with landlines installed by the phone company. As broadband internet connections are available to 95% of Americans, there are many alternatives to consider.
In this guide, we'll tell you about the types of phone systems, explain how they work, and provide a comprehensive comparison of them. Let's dig in!
Types of telephone systems
When considering a phone system for your business, you have many options. Besides handling phone calls, their functionality is much different.
There are three types of phone systems available today: Analog, VoIP, and SIP trunking.
Analog phone systems consist of traditional landlines installed by the local phone company. It's also known as Plain Old Telephone Service (POTS). For business functionality, you might need extra telecom hardware.
Analog phones function in the same way they did more than a century ago. Sound is transmitted using electrical pulses on a wire. These wires connect to the phone service provider.
A company would configure an on-premises Private Branch Exchange (PBX) with one or more phone lines. A PBX creates an internal phone network, placing employees onto a shared phone system.
Dubbed "copper wire," voice service can only travel wherever you trenched and laid wires. Traditional phone service is subject to bad weather, installation, and expensive long-distance charges.
Voice over Internet Protocol (VoIP) uses your existing internet connection for phone calls. It also includes many advanced calling features built into the service.
A VoIP phone system is also known as digital phone service or hosted phone service. It works by converting sound into data packets and transmits them to a VoIP provider. VoIP providers then direct calls between the Public Switched Telephone Network (PSTN).
This happens in milliseconds thanks to blazing-fast cable or fiber broadband internet connections. VoIP lets small businesses get all the best telecommunication features for a fraction of the cost.
In terms of features, landlines are no match against VoIP. If you prefer having more control over your calling experience, VoIP telephones are your best bet.
With VoIP, companies can place and receive calls without any extra hardware. All they need is a computer, laptop, or cell phone to use their business phone system.
Keep in mind that employees are most comfortable with a desk phone. IP phones turn sound into digital signals and maintain connectivity with a VoIP provider.

3) SIP trunking
SIP trunking provides an existing PBX voice connectivity from a VoIP service provider. Trunking requires steep technical skills to operate.
Trunking is a phone service without advanced features businesses might expect. You have to configure voicemail, call forwarding, call routing, auto attendants.
So, what's the advantage of SIP trunking? If you're already managing your PBX and want the cloud's proven scalability and reliability, trunking is for you.
If this sounds like your jam, you'll enjoy our deep-dive into SIP trunking. For the rest of this guide, we'll focus on VoIP vs. landlines.
Three benefits of an analog phone system
Analog phone systems aren't always the wrong choice. In some cases, they can be the best option for business communications.
Landline telephones have time on their side. Millions of miles of copper wires have been installed over the last 140 years. Telephone companies built the telecommunications infrastructure for reach, not necessarily speed. For strictly voice calls, it works.
2) No bandwidth requirements
The 5% who don't have access to broadband impacts more people than you might realize: 16 million people. For a small office, digital phone service requires 100 Kbps per line, which could be more bandwidth than available.
3) Analog equipment
Some offices have devices that need landlines, such as alarms. These depend on a wired phone line to transmit information. An Analog Telephone Adapter (ATA) solves this in many circumstances. Some equipment exchanges data on the line (akin to days of dial-up), and VoIP codecs can interfere.
If you don't have broadband or must keep specific legacy equipment, then analog-based landline service is better for you. If you have a high-speed internet connection, a virtual phone system is best.
Advantages to using VoIP
1) Superior reliability
Voice over Internet Protocol relies on trusted and proven internet technologies with proven reliability. Data packets reach their destinations reliably. Nextiva's business communications network uses several redundant data centers across North America for enterprise-grade reliability.
VoIP lets you handle calls without busy signals or static on the line. You can adjust your call flows instantly. Even if you experience an internet or power outage, you can direct calls to your cell phones. You got this.
2) Greater flexibility
VoIP technology lets you work from home without clients or coworkers noticing a difference. You might even boost productivity without the commute or interruptions. Your work number is secure and private and goes wherever you go — even on your mobile phone.
If you have a computer or smartphone, you can stay connected to the office. Need to take a vacation? You can direct calls to your team or direct them right to your voicemail and screen them via your email. VoIP provides your team with all the top calling features without any extra hardware. It just works.
3) Lower costs
The internet has brought down the costs of many products and services. Pricing for business phone service is no different. Companies can save up to 65% off their communication expenses with internet phone service.
Besides the lower monthly rate as low as $18.95, there are additional savings with no installation fees or bulky telecom equipment. To use VoIP, all you need is a computer or mobile device. Businesses stretch their budget further with built-in advanced calling features included, such as automatic call routing, auto attendants, text messaging, and video conferencing.

Breakdown of phone system costs
If you haven't examined the costs of your commercial phone system lately, you should. Some of your phone bill charges will shock you.
A business phone system's cost isn't just the monthly price, especially if you manage a PBX.
There are several additional costs you have to factor in as well:
- Installation (wiring)
- PBX equipment
- Labor costs to configure
- Advanced features
- System updates
- Training and support
- Commercial real estate
- International calls
Landline phone systems can easily cost several hundred dollars per user every year. Landlines aren't wise in the era of remote work and abundant broadband internet access.
A virtual phone system like Nextiva absorbs these costs into a straightforward monthly rate per user, starting at $18.95.
Which business phone system is best?
A business counts on its phone system to keep employees connected and to serve customers. Most workplaces now have an operational need to enable staff to work from home.
Landline phone service can't match VoIP's flexibility, features, and ease of use. If your existing phone system works and you have no plans to change how you use it, it might be acceptable to keep it.
VoIP phone service is a top choice among enterprises and small businesses. It provides organizations the most scalable and secure ways to communicate. With today's reliable internet service, uptime is never an issue. Plus, it can cut costs by more than half.
As an industry, Unified Communications market growth surged by 25% CAGR last year, while landlines declined by 10%.
