What is VoIP?
VoIP, also known as Voice over Internet Protocol is a technology where your analog voice signals are turned into digital data so that you can make phone and video calls. The traditional communication tools are dependent on PSTN better known as a public switched telephone network; on the other hand, VoIP works over the internet.
How Does VoIP Work?
VoIP has a codec that decodes your voice and encodes it to make it digital; this process is called encoding and decoding. Codec’s main purpose is to highly compress the data so they can be transmitted smoothly and rapidly, thus resulting in a higher quality of the call. VoIP uses digital signals, unlike your traditional telephones which solely rely on PSTN analog data. When you use VoIP, your voice analog data is converted into digital signals. These digital signals are then decoded again in analog form and transferred to the person on the other line so they can listen and comprehend your voice. This entire process of you calling a person using VoIP takes place on the internet.
How are Calls made in VoIP?
There are three ways to make VoIP calls:
- Analogue Telephone Device (ATA) An Analogue Telephone Device is an adapter that lets you connect your analog telephone to the internet and makes VoIP accessible to you. It encodes the outgoing analog data off your phone into digital data. Similarly, it decodes incoming data and encodes it into analog so that you can listen to the sound of the person calling. The installation of ATA is easy and not costly for businesses who are thinking of using VoIP services as it saves thousands of dollars on hardware installations.
- Internet Protocol Phone IP phones may look like common phones but they are made specifically for VoIP. They don’t connect by RJ-11 cable instead, they connect to the internet with the means RJ-45 Ethernet cable. Several options of these VoIP phones are available for businesses, from high ends to entry-level.
- Softphones These phones are software-based phones made for you to use VoIP services on your computer. The design and layout of these software phones are much similar to traditional phones. Skype is a well-known VoIP service provider for computers, mobiles, tablets, and other devices.Most of the softphones are easily available to download over the internet with minimal fees and offer great call plans. However, keep in mind that you need a microphone or speaker (or headset), a sound card, and an internet connection for VoIP software to work on your PC.
