What is VoIP?

VoIP (Voice over Internet Protocol) is a technology that enables voice calls to be made over the internet instead of through traditional telephone lines. 

It converts voice into digital signals that can be transmitted over the internet and then back into voice at the receiving end. This allows for potentially lower costs and the ability to make calls from anywhere with an internet connection.

The global VoIP (Voice over Internet Protocol) services market has witnessed significant growth over the years, reflecting the increasing adoption of digital communication technologies worldwide. Below is a year-by-year breakdown of the D showcasing the dynamic expansion and fluctuations in the industry’s value.

These figures underline the evolving landscape of digital communication, highlighting the industry’s resilience and adaptability in meeting the demands of consumers and businesses alike.

History of VoIP

VoIP (Voice over Internet Protocol) technology evolved from an experimental project in the early 1970s to a major telecommunications system today. Initially used in ARPANET for packet voice calls, it gained commercial traction in the mid-1990s with Vocal Tec’s Internet Phone software. 

The 2000s saw rapid growth with the adoption of broadband and the launch of popular services like Skype. Today, VoIP is integral to unified communications, leveraging cloud technology and improved network capabilities to offer advanced features beyond voice calls. 

This technology continues to evolve, integrating with the latest internet and communication advancements.

How does VoIP work?

Data transmission was an early driver of the internet. Voice communications took more time to emerge as a viable internet application. Improvements in microprocessor speed and memory capabilities made VoIP possible in 1973.

In the ensuing decades, particularly during the mid-1990s, most VoIP phone services evolved from phone services that converted analog voice signals into digital bit streams, using codecs. Those bit streams could then be processed and transmitted in packets over the internet. VoIP technology today uses various elements, as shown here.

Reasons to Use VoIP

🎯Save on costs

Companies can reap big savings when they switch to VoIP because it doesn’t require as much specialized hardware as regular phones do. 

You can use your existing computers, internet provider and smartphones. You just need to download the app for your phone system or VoIP service provider of choice.

🎯Make calls from anywhere

Most modern VoIP providers offer cloud-based calling services, meaning you can make calls from anywhere, so long as you have a softphone app installed on your device. 

You don’t need to have an office phone or be in a physical office to make and take calls.

🎯Enjoy complete portability

VoIP phone numbers are portable. If your small business just moves offices, you can still keep the same phone numbers everywhere.

🎯Increase security

VoIP is hosted over an internet connection, so it typically uses IP technology to encrypt calls and automatically identify potential security threats.

🎯Scale their operations faster

Since VoIP doesn’t require much specialized hardware, it’s much easier and cheaper to add more lines if needed. In contrast, scaling a traditional phone service would require buying additional telephones and lines, which can get costly.

How do I Identify a VoIP Caller?

If you don’t know who’s calling or need to know how to tell if a call is from a VoIP phone number, there are several methods you can use to identify calls from a VoIP phone number or a caller id. You can try:

Using a softphone or hard phone 

If you’re using a softphone or hard phone to send information and receive calls, you can install what’s known as a packet analyzer app to help you log the traffic that comes over your network. If you received a VoIP call, you can use the packet analyzer app to show the IP details of the call, and then look up the IP address.

Checking the domain

Some VoIP calls will show a domain associated with the phone number along with them, similar to an email address. Look up the domain that incoming call appears to find out more about the caller.
