What started as a fringe technology has grown into a mainstream solution that’s transforming how businesses handle calls. With the expansion of high-speed internet and cloud-based services, more companies are questioning whether they still need to pay traditional telecom prices to keep their teams talking.
Today, many businesses are looking closely at their phone bills, wondering if there’s a smarter, more cost-effective way to manage communications without sacrificing quality. In this article, we’ll break down the true costs of VoIP versus traditional landlines so you can decide what makes the most sense for your business and your budget.
Key Takeaways

Understanding the Basics of VoIP and Landlines
What is a landline telephone system?
A landline system uses traditional telephone networks to transmit voice calls over physical copper wires. It requires on-site infrastructure like PBX systems, desk phones, and wiring that connects your office to the local telephone exchange.
While reliable, landlines come with limitations: adding a new line often means additional hardware and technician visits, and if your team grows or shifts to remote work, landlines don’t offer the flexibility to scale or adapt quickly. In many cases, you’re paying for infrastructure that’s tied to a physical location, whether or not your team is in the office.
What is VoIP?
Voice over Internet Protocol is a technology that allows voice calls to be made over the internet rather than traditional phone lines. Calls are converted into digital signals and transmitted using IP networks, enabling voice communication through the same internet connection you already use for email, video conferencing, and cloud tools.
Instead of requiring on-premise hardware tied to physical wiring, VoIP systems often use software, cloud platforms, or VoIP-enabled desk phones. It makes it easy for businesses to manage calls from anywhere, whether your team is in the office, working remotely, or on the go. VoIP even offers a range of features that traditional landlines don’t, from voicemail-to-email to advanced call routing and analytics.
Cost Breakdown: VoIP vs. Landline
Upfront costs
With traditional landlines, you typically face installation fees for each line, plus the cost of PBX systems and wiring throughout your office. If you need to expand, adding lines requires additional hardware and labor, but in general, the upfront costs are relatively clear and straightforward.
VoIP systems, on the other hand, usually have lower upfront costs. If you’re using a softphone setup, your existing computers and headsets may be enough. Even with VoIP desk phones, setup is generally simpler since it leverages your existing internet infrastructure without complex wiring.
Monthly/recurring charges
Landline services often charge a fixed monthly fee per line, with additional costs for long-distance or international calls. The pricing can vary by provider and location but typically doesn’t include advanced features without extra fees.
VoIP uses a subscription model though, based on the number of users or bundled minutes. Many VoIP providers offer plans that include unlimited domestic calls and competitive rates for international calls, helping businesses manage recurring costs more predictably.
Hidden or additional charges
Landlines can come with hidden costs, including maintenance fees, long-distance charges, and upgrade costs for hardware. If something breaks, repairs can be slow and expensive, which makes it a less predictable option when it comes to overall cost.
VoIP systems may have additional fees if you choose premium features, such as advanced analytics or integrations, and your internet plan may need to be adjusted to handle increased data usage if your team makes heavy use of VoIP calls. But even with these add-ons, many businesses find VoIP costs stay lower than traditional telecom fees over time.
Benefits of VoIP Over Traditional Landlines
Choosing VoIP isn’t just about reducing your monthly phone bill; it’s about building a communication system that fits how modern businesses operate. Let’s look at some of its benefits:
- Lower operating costs: VoIP typically reduces both upfront and ongoing costs, freeing up budget for other priorities.
- Remote and mobile flexibility: Team members can make and receive calls from anywhere with an internet connection, supporting remote work and business travel.
- Integration with tools: VoIP can integrate with your CRM, helpdesk, and collaboration platforms, creating a seamless workflow for your team.
- Access to advanced features: Features like call routing, voicemail-to-email, and call recording are often included or available at a lower cost than with traditional systems.
- Easy scalability: As your business grows, you can add new users or lines quickly without major infrastructure changes or service disruptions.
Potential Drawbacks and Considerations
While VoIP offers clear advantages, it’s not without its challenges. The biggest dependency is your internet connection; if your bandwidth is limited or your network is unstable, call quality can suffer, leading to dropped calls or choppy audio.
Security is another consideration. Without proper configuration, VoIP systems can be vulnerable to hacking or spam calls, which means you’ll need a strong IT strategy and reputable providers with encryption and security monitoring to help mitigate these risks.
There can also be a learning curve, especially for teams used to traditional desk phones. Don’t forget to train and offer clear onboarding to help your team adjust to the new call management system. Plus, it’s worth noting that in areas with unreliable internet, VoIP might not always deliver consistent call quality, which could impact customer-facing teams.
Real-World Cost Comparison Examples
Small business
Let’s say you’re a small business with five users. A traditional landline setup might cost around $30–$50 per line per month, plus taxes and fees, totaling roughly $200–$250 monthly. Add maintenance or hardware upgrades, and your yearly spend can easily exceed $3,000.
Switching to VoIP, you might pay $15–$25 per user monthly, with many providers bundling unlimited domestic calls and advanced features. For five users, this could bring your monthly cost down to $75–$125, or $900–$1,500 annually—cutting your communication costs in half while gaining more flexibility.
Enterprise-level
For larger businesses with 50+ users, traditional landline systems can become costly, especially when you add in PBX maintenance and long-distance charges. Monthly costs can reach $2,500–$3,500 or more.
With VoIP, even after initial investments in headsets or VoIP-enabled phones, the monthly per-user cost remains lower, often around $750–$1,250 per month for 50 users, depending on the feature set. Over a year, enterprises can save tens of thousands, funds that can be reinvested into growth or customer initiatives.
Factors That Influence VoIP Costs
Not all VoIP setups cost the same. There are many factors that shape your pricing:
- Provider pricing models: Choosing the right model based on your call volume impacts your bill. Some providers offer metered plans (pay per minute), while others provide unlimited calling or hybrid models.
- Number of users and simultaneous calls: More users and higher call concurrency may require additional licenses or bandwidth.
- Feature sets and add-ons: Features like advanced call analytics, AI transcription, or CRM integrations may add to your subscription costs.
- Internet bandwidth and setup: You may need to upgrade your internet plan or invest in routers that prioritize VoIP traffic for optimal performance.
Choosing the Right Solution for Your Business
Before switching to VoIP, ask yourself:
- Is your internet reliable enough for consistent call quality?
- How many users and lines do you need?
- What call features are essential for your operations?
- Do you need integration with existing tools like your CRM?
- What support does the provider offer if issues arise?
Compare multiple providers and evaluate their customer support, contract terms, and feature sets. Some businesses opt for hybrid models, using VoIP as the primary system with a landline fallback for emergencies or specific compliance requirements.
And always take advantage of trial periods when available, allowing your team to test VoIP systems without long-term commitments before making the switch.
VoIP Cost-Saving Tips for Maximum ROI
To get the most value from your VoIP investment:
