Introduction to VoIP(Voice over Internet) application and their usage

VoIP apps, also known as softphones, are software applications that let you make phone calls and video calls over the internet, instead of using traditional phone lines. Think of them as digital replacements for your landline or mobile phone service. Here’s what you need to know about them:

How they work:

  • These apps use the Voice over Internet Protocol (VoIP) technology to transmit your voice data in digital packets over the internet. You don’t need a physical phone line, just a stable internet connection (Wi-Fi or mobile data) and the app installed on your device (smartphone, tablet, computer).

What they offer:

  • Free or low-cost calls: Many VoIP apps offer free calling between users on the same app, and very cheap rates for calling traditional phone numbers, both locally and internationally.
  • Multiple features: Besides voice calls, many apps also include features like video conferencing, text messaging, file sharing, call recording, voicemail, and more.
  • Device flexibility: You can use the same app on different devices, allowing you to seamlessly switch between them for calls.
  • Mobility: As long as you have internet access, you can make and receive calls from anywhere, making them ideal for remote work and travel.


  • Cost savings: Compared to traditional phone services, VoIP apps can significantly reduce your call costs, especially for international calls.Increased mobility and flexibility: Make calls from any device with internet access, regardless of your location.
  • Enhanced features: Enjoy features like video conferencing, call recording, and integrations with other tools.
  • Improved accessibility: Many VoIP apps offer accessibility features for people with disabilities.
