Introduction to VoIP (Voice over Internet Protocol)

VoIP(Voice Over Internet Protocol) phone system is a technology that carries your voice through the internet connection. It is also known as internet calling, IP telephony, or voice-over network. 

VoIP technology uses a broadband internet connection instead of a traditional phone line to make and receive phone calls. Voice over Internet Protocol (VoIP) converts human speech signals into digital data, which can be transmitted over the Internet. 

Modern VoIP phone systems enable businesses worldwide to operate more effectively by replacing traditional landlines. Skype is an example of VoIP software that is popular for video calls.

VoIP phone systems have made communication easier for businesses, as they can be easily accessed via the Internet. Moreover, VoIP services offer greater services and features than traditional phone lines.

  • It provides Portability and flexibility since it operates through the internet
  • Effortless cancellation
  • Low call rates without roaming charges 
  • Scalable for growing businesses 
  • Advanced features for business-driven works
  • Highly encrypted security


  • Requires A good, stable internet connection
  • During calls, there may be latency

Comparing VoIP and Traditional Landlines

While VoIP and traditional phone systems have similar functions, they differ in a number of ways. We have made a comparison table of VoIP and traditional phone systems to help you decide which is best for your business. There are a number of features available, including call routing, forwarding, auto attendant, predictive dialer, video conference calling, call analytics, and more.

Let's compare them based on the following criteria:

Comparison: Traditional Phone System vs. VoIP Phone System

Criteria Traditional Phone System VoIP Phone System
Cost Traditional phone system needs a physical setup with special hardware components and a service and maintenance charge, so the cost is higher. The cost of setting up a VoIP phone system is lower since no special hardware devices are needed. Free setup is available from some providers.
Features Voicemail and basic call handling are the only features available on the traditional phone system. There are a number of features available, including call routing, forwarding, auto attendant, predictive dialer, video conference calling, call analytics, and more.
Call Quality Traditional phones provide reliable and consistent call quality. Whenever there is a problem with a wire or server, disruption occurs. Internet connection affects the quality of calls. When the internet connection is bad, disruption occurs. Otherwise, the quality of the call is stable.
Installation and Set up Using wires and hardware equipment can be time-consuming and difficult. Setup is quick and easy. In just a few minutes, it can be activated.
Mobility As traditional phone systems tether users to physical locations, mobility is restricted. Provides flexibility and mobility for remote workers since it requires an internet connection and a virtual phone number provider's app.
Scalability Adding or removing lines can require additional hardware setup, charges, and other changes. Scalable by requesting the provider to add or remove lines via phone calls with minimum effort. No additional equipment or devices are required.
Support and Maintenance It requires systematic and regular maintenance and support. For updates and maintenance, the support team must be physically present. Maintenance and updates are minimal. System configuration or app updates can be done remotely by customer service.
Integration There are limited integration capabilities; only PBX systems can be integrated with traditional phone systems. The platform supports integrations with CRMs, PBXs, and ERPs, as well as Google, Slack, and Microsoft 365.
Reliability It is reliable and does not require an internet connection. Communication depends on an internet connection; an unstable connection can disrupt it.
Security With proper security protocols, it can be made immune to hackers and security breaches. Even though it's more secure than traditional lines, hackers can still access your phone lines, and physical security is still possible.
Accessibility There is limited access to features, as well as limited global accessibility bounded by geographic location. Users can access global accessibility from anywhere in the world, with unlimited access.
Call Cost Long-distance and international call rates are expensive. Since virtual phone services are based on subscription plans and packages, VoIP calls are affordable.

Reasons to Switch to VoIP

From the above table, it is clearly seen that VOIP services can fulfil the business's needs. Here are some additional reasons why businesses should switch to VoIP. 

  • Cost savings and efficiency improvements: VoIP does not require hardware equipment and regular maintenance, also the long distance calls are roaming free, which can save customers a significant amount of money.

Limited Emergency Services

Customers using VoIP phone systems can face limitations on emergency services. If there is an emergency, VoIP users cannot dial 911. Service providers or Internet service providers impose limitations. In order to call emergency services, customers must have an alternative method.

Evaluation of security concerns

Training should cover all aspects of using VoIP phones, including setting up calls correctly, understanding caller ID information, transferring calls appropriately, and troubleshooting problems quickly.

It is important that employees have all the necessary knowledge before taking customer inquiries or complaints over either type of telephone system.

3. Monitoring and troubleshooting issues

IT personnel should be able to identify and resolve technical difficulties efficiently if necessary, by implementing monitoring systems.

When a caller cannot be reached, automated alert mechanisms should be implemented. By analysing dropped calls, improving call quality, and impressing clients, it is possible to improve call quality. 

Your business communication operations will be significantly improved by using these processes to reduce technical issues and reduce downtime.

4. Evaluation of the impact of the chosen system on business operations

Business owners should evaluate how well VoIP phones perform in their specific environment. The factors that could be measured include average handle times, abandonment rates, first-time resolution rates, etc.

It may even be necessary to run tests under identical conditions in which different types are compared.

In this way, it would be possible to determine which one provides better performance results. Evaluate VoIP telephony infrastructure solutions before making a decision. Based on those findings and measurements, it is possible to determine the best course of action going forward.


We hope this article helps you to determine the difference between traditional and VoIP phone systems. Before choosing the phone system for your business, you should be clear about your needs. 

While both have unique features, overall, VoIP is better than traditional phone systems as it has more features, is flexible, and can fulfil your business needs.  Cloud telephony can contribute to your business's success and growth.
