Vonage looks at the different elements that go into determining VoIP vs. landline costs to give you the fuller picture of what to expect.
If you’ve heard of VoIP phone systems but are worried they will raise your businesses phone bills, we have a nice surprise for you. In general, VoIP systems save businesses money over traditional landline phones.
This is especially true if you leverage the additional features available through VoIP to improve other areas of your business that traditional phones can’t help you with.
Yes, for most businesses, VoIP is a more cost-effective solution than landlines or legacy PBX systems. It works over your existing internet connection, cutting out the need for separate wiring or expensive hardware. On top of that, VoIP often includes more built-in features at a lower monthly rate.
VoIP is generally more affordable than traditional phone systems because it works over your existing internet connection and devices, with no need for dedicated phone lines, separate cabling, or extensive hardware setups.
Beyond lower setup costs, VoIP delivers operational value that helps businesses save in other areas:
For small and midsize businesses in particular, these savings can add up quickly, making VoIP a smarter long-term investment than a traditional landline.
As noted earlier, VoIP systems typically deliver significant cost savings over traditional landlines.
In fact, studies have shown that businesses save on average between 30% and 50% on their phone bill each month when they switch to VoIP. So it’s no surprise that 31% of businesses currently use VoIP, and that number is growing all the time.
To understand the full financial impact, it helps to compare both systems across initial costs, ongoing expenses, and hidden fees.
Traditional landlines may require installation fees, desk phones, and on-premises PBX hardware, especially costly for large offices or multi-location businesses.
VoIP systems are easier to set up. Many companies launch with softphones on existing laptops or smartphones. Even when IP desk phones are needed, they’re typically plug-and-play, with no technician required.
Bottom line: VoIP offers a more budget-friendly, scalable setup, ideal for remote or fast-growing teams.
Legacy phone systems charge per line and often tack on fees for voicemail, call forwarding, or long-distance. Monthly totals can add up fast.
VoIP plans usually charge per user and bundle in most essential features, from call routing to voicemail-to-email, keeping billing predictable and easier to manage.
Landlines can introduce unexpected costs for maintenance, upgrades, or international calling.
In contrast, VoIP providers tend to bundle support and system updates into their base plans. Scaling is simpler and less expensive, often just a matter of adjusting your plan online.
While VoIP may have costs for premium features or high call volumes, cloud-based infrastructure makes it easier to control expenses and avoid surprise fees.
Understanding the upfront costs and monthly cost differences can help clarify why VoIP is often the more affordable choice. Here’s a high-level comparison:
| Cost Category | VoIP System | Traditional Landline |
|---|---|---|
| Monthly Service | $15-$40 Per User | $50-$100 Per Line |
| Long-Distance Charges | Included in Most Plans | Extra Per Minute |
| Voicemail, IVR, Call Forwarding | Bundled With Base Plans | Add-on or Not Available |
| System Maintenance | Included With Provider | Often Requires External Support |
| Hardware Needs | Minimal; Works on Existing Devices | Desk Phones, Wiring, PBX Setup |
These recurring costs can add up quickly for traditional landline systems, especially when scaling or adding new features.
VoIP pricing typically offers lower base costs with a broader range of built-in capabilities, helping reduce both fixed and variable expenses over time.
If you’re wondering how VoIP savings stack up in real-life scenarios, here’s a comparison of typical monthly and annual costs for different business sizes.
| Expense Type | Traditional Landline | VoIP System |
|---|---|---|
| Setup and Installation | $300-$500 | $0-$100 (Softphone Setup) |
| Monthly Cost (5 Lines) | $300-$500 | $75-$200 |
| Long-Distance Calls | Charged Per Minute | Included in Most Plans |
| Maintenance | Pay as Needed | Included in Service Plans |
| Estimated Annual Cost | $4,300-$6,200 | $900-$2,400 |
| Expense Type | Traditional Landline | VoIP System |
|---|---|---|
| Setup and Installation | $5000 -$10,000 | Less than $500 (If Any) |
| Monthly Cost (50 Lines) | $3000-$5000 | $750-$1,500 |
| Long-Distance Calls | Charged Per Minute | Included in Most Plans |
| Maintenance | Pay as Needed | Included in Base Plan |
| Estimated Annual Cost | $45,000-$70,000 | $9000-$18,000 |
These examples show how VoIP can reduce costs for businesses of all sizes, especially as you grow. With fewer setup requirements, lower monthly fees, and bundled features, VoIP delivers value that legacy systems often can’t match.
VoIP (Voice over Internet Protocol) and landline systems use fundamentally different technologies. A VoIP phone line transmits voice as data packets over the internet, while a traditional landline uses analog signals sent through copper wires on the Public Switched Telephone Network (PSTN).
These differences bring key functional advantages for VoIP:
While landlines still offer simplicity, VoIP’s internet-based design offers far more agility and customization, making it a better fit for most modern businesses.
With VoIP, the savings don’t stop at your monthly phone bill. Many VoIP systems include built-in features that would otherwise require expensive add-ons or third-party software with traditional phone setups.
Instead of paying extra for conferencing, voicemail tools, and CRM plug-ins, many VoIP platforms include them.
Here are a few feature-driven ways VoIP helps reduce costs:
When bundled into a single solution, these advanced VoIP features not only reduce operating costs but also enhance productivity and customer experience.
For many businesses, especially those in finance, healthcare, or legal services, cost isn’t the only concern — security, compliance, and reliable connectivity matter just as much.
Modern VoIP systems use encryption and secure protocols to protect call data in transit. At Vonage, for example, VoIP services are backed by enterprise-grade security practices and third-party certifications such as ISO 27001, PCI DSS, and HIPAA-compliant offerings for eligible customers.
Many VoIP providers offer features to help meet industry-specific regulatory requirements. This may include call recording controls, audit trails, and admin-level access restrictions, all essential for businesses handling sensitive data.
Reliable VoIP platforms come with call failover options, multiple data centres, and uptime guarantees. These redundancies help keep communications running even during local network issues.
Some providers also offer mobile backup options, allowing users to continue calls on cellular data if the internet goes down.
IT teams can also configure QoS settings on business networks to prioritize voice traffic, ensuring clear, uninterrupted call quality.
Together, these elements make VoIP a secure and resilient solution that meets the needs of modern, compliance-conscious organizations.
Even though VoIP has become the go-to solution for modern business communication, a few persistent myths still create hesitation. Let’s set the record straight.
Reality: VoIP is often much cheaper than landlines, especially when you factor in bundled features like voicemail, call forwarding, and conferencing. With landlines, these tools typically come at an extra cost, or aren’t available at all.
Reality: Most businesses can start using VoIP with the devices they already own, like smartphones, laptops, or tablets.
Softphone apps eliminate the need for desk phones, but if you prefer physical hardware, plug-and-play VoIP phones are easy to add.
Reality: Call quality depends more on your internet connection than on VoIP itself. With a strong, stable network, VoIP can deliver clear calls, often better than traditional landlines.
Reality: Today’s VoIP platforms are built for ease of use. With user-friendly dashboards and simple setup, even the smallest teams can manage their phone system without technical help.
Reality: VoIP uses very little bandwidth and won’t noticeably affect internet speed. That said, if your internet is already slow or unstable, it may impact call quality, so a reliable connection is key.
VoIP isn’t just cost-effective, it’s also accessible, scalable, and easier to use than many assume.
