Clear, reliable communication is the backbone of any successful business. But with today’s evolving technology, many companies are asking the same question: Is it time to upgrade from a traditional phone system to VoIP?


At BT Services, we work with businesses across Missouri to ensure they have the right phone system in place—whether that’s maintaining a legacy system or transitioning to something more modern. Let’s break down the key differences so you can make an informed decision for your organization.


What Is VoIP?

VoIP (Voice over Internet Protocol) allows you to make phone calls using your internet connection instead of traditional copper phone lines. It’s a flexible, cloud-based technology that opens the door to a variety of communication features—without the hardware limitations of older systems.


What Is a Traditional Phone System?

Traditional systems, often referred to as legacy PBX systems, rely on physical phone lines and on-site equipment. These systems have been around for decades and are known for their reliability and stability.


Key Differences: VoIP vs. Legacy Phone Systems

1. Cost Efficiency

  • VoIP: Typically has lower monthly costs, especially for long-distance or international calls. It uses your existing internet connection and eliminates many traditional telecom fees.


  • Traditional Systems: Higher upfront installation costs and ongoing maintenance expenses. Service fees for changes and updates are more common.

2. Scalability

  • VoIP: Easily add or remove users as your business grows. Ideal for teams working remotely or across multiple locations.



  • Traditional Systems: Expanding often requires new hardware or additional wiring, which can drive up costs.

3. Features and Flexibility

  • VoIP: Offers features like call forwarding, voicemail-to-email, video conferencing, and mobile integration.



  • Traditional Systems: More limited in features without additional hardware or service upgrades.

4. Reliability

  • VoIP: Depends on internet quality. A strong, stable connection ensures clear calls and minimal downtime.


  • Traditional Systems: Known for their stability, especially in areas with unreliable internet. Some businesses still prefer these for mission-critical reliability.

5. Maintenance and Support

  • VoIP: Requires minimal on-site equipment, with many systems managed remotely.


  • Traditional Systems: May require specialized support for legacy hardware. BT Services is one of the few providers in the region that still services legacy phone systems.

So, Which Is Right for You?

If your business has a strong internet connection, a need for flexibility, and wants to cut costs, VoIP is likely the best choice. However, if you’re using a legacy system that’s still working well—and your operations depend on guaranteed uptime—it might make sense to maintain your current setup, at least for now.


At BT Services, we don’t push a one-size-fits-all solution. We take the time to understand your current system, your needs, and your goals. Whether you’re ready to upgrade to VoIP or simply need expert support for your traditional phone system, we’re here to help.
