What Is A Landline?
An effective communication system is highly essential for your business, and choosing a communication system is a make-or-break decision. When choosing between a landline and VoIP phone system, you must consider several factors, such as setup and calling cost, functionality and reliability. In this digital age, you may think that a landline is an outdated setup, but this traditional system may offer several benefits for small businesses.
However, due to its advanced features and benefits, the VoIP phone system is becoming highly popular among businesses. You must understand landline and VoIP phone systems to choose the right communication system. In this article, we will provide a brief comparison between VoIP and landlines. It will help you determine the type of setup your business needs.
How Do Landlines Work?
Landline phone systems, also known as Plain Old Telephone Services (POTS), are analogue systems traditionally set up by local phone providers. These systems transmit sound through electrical pulses sent along wires that connect directly to the provider.
Companies often integrate an on-site Private Branch Exchange (PBX), which establishes an internal phone network and allows employees to share a unified telephone system. This setup relies on physical copper wires, limiting voice service to areas where the wires are installed. However, traditional phone systems are vulnerable to challenges such as adverse weather conditions, complex installations, and costly long-distance calls.
Despite these limitations, landlines offer certain advantages. They leverage a well-established infrastructure, do not require additional bandwidth, and are better suited for legacy analogue equipment than VoIP systems.
Popular Features Of Landlines

Over time, landline phone systems have incorporated several practical features to enhance functionality:
i. Caller ID
This feature displays the name and number of incoming callers on your phone’s screen, allowing you to see who’s calling before answering. It’s a valuable tool for screening unwanted or unfamiliar calls.
ii.Call Waiting
Call waiting lets you manage multiple calls simultaneously by notifying you of an incoming call while you’re already on another. A tone alerts you to the second call, allowing you to place the current caller on hold and answer the new one.
iii. Call Forwarding
Similar to VoIP systems, landlines support call forwarding. This feature redirects calls from your landline to another number, such as a mobile phone or another landline.
iv. Three-Way Calling
This functionality enables conversations with two other people on the same call. While speaking with one person, you can press a button, dial a second number, and connect the second person to the call. Once connected, all three participants can communicate on the same line. This feature is also available on smartphones and business phone system apps.
Equipment Required for a Landline System
Setting up a landline system is straightforward and requires just a few components:
- Base Station: The Central system’s main hub connects to the phone service provider.
- Handset: The device you use to make and receive calls. In cordless systems, the handset communicates wirelessly with the base station, while in corded systems, it is attached to the base with a coiled cord.
- Landline Cord: This is a cable that connects the base station to the wall socket, linking your system to the phone service network.
These essential pieces make landline systems easy to set up and use while maintaining reliable functionality.
Pros And Cons Of Landlines
While landline systems might seem outdated in today’s digital age, there are still compelling reasons to use them. Here we are describing their advantages and disadvantages:
Pros Of Landlines
1. Reliability:
Landline phones are incredibly dependable since they use physical wiring for connectivity. It ensures consistent service without interruptions or dropped calls, which is crucial for small businesses that must maintain seamless operations and ensure customers can always get in touch. During natural disasters or severe weather conditions, landlines often remain operational and can be repaired faster than internet-based systems, minimizing downtime.
2. Consistent Call Quality:
For those with unreliable internet service, landlines provide superior sound clarity and stable call quality. They eliminate concerns about dropped calls or fluctuating audio quality that can occur with internet-based phone systems.
Cons Of Landlines
1. Outdated Technology:
The global shift toward digital and internet-based communication systems has made traditional landlines less relevant. Unlike VoIP systems, landlines don’t offer the flexibility of making calls from anywhere, which can limit a business’s mobility and scalability.
2. Higher Costs:
Maintaining a landline system can be costly. Features like voicemail, call waiting, or caller ID often come at an additional price, and landline services are subject to taxes and fees that further inflate expenses. In contrast, VoIP systems offer these features at a lower cost or as part of standard packages.
3. Susceptibility to Spam Calls:
Landlines are more prone to receiving spam calls than mobile or VoIP numbers. While telemarketers are generally prohibited from calling cell phones, no similar regulations protect landline numbers, making them a frequent target for unsolicited calls.
What Is VoIP?
Voice over Internet Protocol (VoIP) is a communication technology that combines hardware and software. It enables phone calls over the Internet instead of traditional landlines that rely on wires or optical fibres. VoIP is also referred to as internet calling or IP telephony.
VoIP can be used across devices, such as regular phones, smartphone apps, computer software, and specialized VoIP-enabled phones.
How Does VoIP Phone System Work?
Voice over Internet Protocol (VoIP), often referred to as digital phone service or hosted phone service, is a communication technology that converts sound into data packets or digital signals. These signals are then transmitted to a VoIP provider, which routes the calls through the Public Switched Telephone Network (PSTN).
This process occurs almost instantly, thanks to high-speed cable or fibre-optic internet connections. VoIP allows small businesses to access advanced telecommunication features at a fraction of the cost of traditional systems.
VoIP enables businesses to make and receive calls without additional hardware. To connect to the business phone system, all that is required is a computer, laptop, headset, or mobile phone.
VoIP uses an existing internet connection and offers many advanced features, such as auto-attendants, interactive voice response (IVR), call routing, conference calls, and more, which are often included in the service.
Popular Features Of VoIP
VoIP systems offer a range of features that make them an attractive choice for businesses. Some of the most popular features include:
1. Virtual Receptionist
A virtual receptionist, or virtual assistant, automates many tasks typically handled by a human receptionist. It can answer calls, provide recorded messages, direct calls, and offer other essential services. This feature is common in customer support lines, where automated directories help address customer inquiries before involving a live agent. VoIP systems integrate these capabilities, making them efficient for businesses.
2. Automatic Call Forwarding
Automatic call forwarding is a key feature for VoIP users, allowing calls to be redirected to another number of your choice. It can benefit individuals on the move, such as forwarding office calls to your mobile phone while travelling. For remote teams, calls can be automatically forwarded to employees’ smartphones, eliminating the need for physical desks or landline phones. This feature gives businesses greater control over call accessibility.
3. Three-Digit Dialing
Like emergency services, VoIP systems allow businesses to assign a unique three-digit code for quick and easy dialling. It simplifies reaching frequently contacted staff members, vendors, or departments. With three-digit dialling, users can quickly connect to essential contacts with minimal effort, enhancing efficiency.
4. Voicemail to Email
Voicemail-to-email sends recorded voicemail messages to your email inbox as audio files. This feature doesn’t convert messages into text but makes it easier to listen to, save, and share voicemails. In some versions, you can even delete voicemail messages directly from your email, streamlining message management and improving user convenience.
