What is VoIP?

VoIP is an abbreviation for Voice over Internet Protocol. VoIP is simply an advanced communication technology that allows voice calls to be made over the internet.

Advantages of VoIP

VoIP technology has presented so many advantages to business owners, and it is also used by individuals who need a reliable phone to make a lot of phone calls at a cheaper rate.

Here are the top advantages of having a VoIP phone installed in your office or home…

Making Voice Calls with a VoIP Phone is Cheaper

Now, there is a way to save more money from the income generated by your business. VoIP phone calls are cheaper because the connection is made over the internet, rather than through traditional telephone cables.

VoIP Settings are Scalable

You can enjoy VoIP technology regardless of the type or size of your business, and you will only pay for the services that you need, which makes VoIP cost-effective.

Also, necessary changes can be made to meet the growing demand for communication as your business grows.


VoIP can be used at any location – all you need is an internet connection.

Secure Voice Calls

All phone calls made over the VoIP network are secure, so you do not need to worry about compromising confidential information.

How VoIP Technology Works

When a voice call is initiated, the speaker’s voice is converted to a digital signal, which is transmitted over the internet, through an IP, to the recipient. The VoIP technology at the other end interprets the digital signal, and the receiver hears what the caller is saying.

Transmission of digital voice signals is done via secure Real-Time Transport Protocol, which is encrypted for confidentiality. The transmission line remains open, during a two-way communication, until the call is ended.

VoIP technology also allows users to send voicemails. When it is installed on a computer or mobile device, the communication is done via the speakers and microphones on the devices.
