What are the main differences between traditional PSTN communications and VoIP?

VoIP generally offers lower operating costs, greater mobility, easier expansion, and the ability to add users and extensions without complex telephone wiring. It also supports features such as conference calling, voicemail, call recording, remote working, and computer and mobile applications.

Can VoIP reduce local and international communication costs for companies?

Yes. VoIP can help reduce communication costs, especially when connecting multiple branches, supporting remote employees, or managing international calls through a unified system. The actual savings depend on call volume, service type, provider pricing, and the infrastructure used.

What are the security requirements for internet-based communication systems?

Internet-based communication systems require a stable network, suitable infrastructure, and reliable or backup power. They should also be protected with firewalls, strong passwords, encrypted communications, regular updates, restricted access, and monitoring for unauthorized connection attempts.

What services do internet-based communication systems provide?

Internet-based communication systems may provide interactive voice response, call forwarding, call recording, voicemail, audio and video meetings, call reports, mobile and desktop applications, branch connectivity, and integration with customer relationship management systems.

How can a company begin switching to VoIP?

A company should begin by reviewing the number of users, telephone lines, branches, and call volume. It should then assess network and internet readiness, define the required features, choose between an on-premises or cloud-based system, test the service, and train employees before completing the migration.

Why Upgrade to VoIP? The Real Cost of Keeping Traditional Phones

Q: What is VoIP technology?

VoIP stands for Voice over Internet Protocol. It is a technology that transmits voice over IP networks and allows users to make and receive calls through IP phones, computer applications, mobile applications, and compatible communication devices.

Q: Why should companies switch to VoIP and internet-based communications?

Switching to VoIP can help companies reduce communication equipment and call costs while giving employees greater flexibility to work from different locations. It can also support video meetings, branch connectivity, flexible call routing, and detailed communication reports that may not be available with the same flexibility in traditional telephone systems.

If you want to cut your company’s phone bills and gain access to advanced features that traditional phone systems can’t offer—such as allowing employees to work from anywhere, hosting video meetings, or generating detailed communication reports—then VoIP (Voice over Internet Protocol) is the ideal solution for your business.

We’ve previously explained in detail what VoIP is and its main advantages (you can read that article here). In this article, we’ll show you why it’s time to replace your old communication system with a modern, Internet-based VoIP system.

Key Facts and Statistics

Companies save 50% to 75% on communication equipment costs after switching to VoIP.
Businesses typically reduce their monthly communication expenses by around 50% using VoIP. (Source: www.itworld.com)
Global investments in VoIP-related technologies were projected to reach $88 billion by 2018. (Source: www.infonetics.com)
Traditional landline companies lose around 700,000 customers per month to VoIP. (Source: www.infonetics.com)
By the end of 2017, there were over 1 billion VoIP users worldwide. (Source: www.technews.tmcnet.com)

These figures clearly show that the future of business communication lies in VoIP. Internet-based systems are rapidly replacing traditional telephony across companies and institutions worldwide.

Comparison: Traditional Telephony vs. VoIP

IP Phone VS PSTN Comparison

The following comparison highlights the key differences between traditional phone systems and VoIP:

Feature	Traditional Phone Service (PSTN)	Voice over Internet Protocol (VoIP)
Installation Cost	Typically high in most cases	Varies by setup; computer-to-computer calls are often free—only equipment costs apply
Operating Cost	Based on usage time	Much cheaper; no per-minute costs once implemented
Equipment	Low-cost but limited functionality	Provided by the service provider; requires modern IP-based devices and good infrastructure
Mobility (Flexibility)	Fixed and non-portable	Fully mobile; accessible from anywhere via the Internet
Features	Basic call functions (dial, receive, hold)	Includes advanced features like voicemail, group calls, and video conferencing
Reliability	Highly reliable	Very reliable with stable power and Internet connection
Security	Generally secure	Secure with firewalls and encryption, though network precautions are needed
Scalability	Difficult to expand; requires new wiring and possibly construction	Easy to scale—just add new VoIP phones or software users

Why VoIP is the Better Choice

From the comparison above, it’s clear that VoIP has become the practical and flexible alternative to traditional phone systems. It offers:

Reduced communication costs—especially for international calls
Simplified scalability and management
Enhanced flexibility, allowing calls and meetings from anywhere
A wide range of modern features that improve collaboration and productivity

Transitioning to VoIP technology helps companies reduce the costs of communication equipment and calls, while giving employees greater flexibility to work from anywhere. It also supports video conferencing, branch connectivity, call forwarding, and detailed communication reports—capabilities that are difficult to provide with the same flexibility in traditional phone systems.

What are the key differences between traditional communications (PSTN) and VoIP technology?

VoIP technology is characterized by lower operating costs compared to traditional phones, high flexibility to move around and use the service from anywhere, and ease of scaling and adding new lines without the need for complex wiring, in addition to supporting group calls and voicemail.

What are the requirements and security considerations for using internet-based communication systems?

These systems fundamentally require good infrastructure and a stable power source. Although most devices come equipped with a firewall and offer a high level of security, necessary security measures must still be taken to protect them from breaches, like any other data network.

What is meant by internet-based communications?

Internet-based communications are systems that transmit voice and video calls over data networks using Internet Protocol, instead of relying entirely on traditional telephone lines. The technology for transmitting voice calls over the internet is known as VoIP.

Does VoIP help reduce international and local communication costs for companies?

Yes, voice-over-internet-protocol technology significantly reduces communication costs (especially international ones), because it relies on transmitting voice via internet data packets instead of traditional landline networks tied to long usage hours.

What services does internet-based communication provide?

Internet-based communication services may include:

IVR (automated response)
Call forwarding
Call recording
Voicemail
Voice and video conferencing
Call reports
Mobile and computer applications
Branch connectivity
Integration with CRM systems

How does a company start transitioning to VoIP technology?

The company begins by analyzing the number of users, lines, branches, and call volume, then checks the readiness of the network and internet, chooses a local or cloud-based system, trials the service, and trains employees before implementing the full transition.
