Understanding VoIP from the Basics

VoIP Algorithms

VoIP technologies

Unlike in traditional telephony, there are various ways in which you can make VoIP calls. The most common ways you can use to connect using the best VoIP service for business include:

ATA – Analogue Telephone Device

An analog telephone device is an adapter which enables you to use a VoIP service using your analog phone. It, therefore, connects your internet service to your phone. Its function is to encode the outward-bound analog signal from the phone into a digital form which can be transmitted via the internet. Similarly, it will also accept inbound digital signals and decode them into analog sounds that you can hear and comprehend.

As such, when it comes to moving from your traditional phone service to VoIP, the ATA is a convenient tool that will potentially save you or your business thousands of dollars to purchase new hardware.

IP Phones

An Internet Protocol (IP) Phone resembles your typical phone. However, it is designed specifically for internet telephony. Thus, instead of using an RJ-11 phone cable to connect to the wall socket, an IP Phones connects to your router via an RJ-45 ethernet connector. This implies that you do not need an ATA if you have an IP handset.


A softphone refers to the software that loads a VoIP protocol onto your pc. It often uses an interface that resembles the traditional phone. A consumer softphone that you might be well aware of is Skype.

And even though business-grade softphone packages might not always be free, this software is not likely to break the bank, thus ensuring that you save a lot on your calls. To get started with a softphone, you will need the VoIP software, a sound card, speakers, and an excellent internet connection – just like in any other kind of VoIP.
