Within the last two decades, the world has observed some major advancements in the technology sector. From landlines to free phone calls via VoIP apps and so on.

As the name suggests, VoIP requires an internet connection to make and receive calls. It has been in use since 1995 back when it was termed “Internet Phones”. Fast forward to today, VoIP has expanded so much that people even refer to it as the VoIP industry.

VoIP makes it not just possible but also affordable to connect employers with employees and clients. It doesn’t matter whether they reside locally or abroad – VoIP is making sure that they connect regardless of the geography.

What is a VoIP app?

In this app-driven world, it is nearly impossible not to mention any app that lets you connect with others. VoIP apps are specially developed for the sole purpose of communication. There’s a high chance that you’re currently using one of the apps.

These apps are so user-friendly that all you need to do is get a VoIP number, download the app, log in with your credentials, and start using them. Just like that! No extra configuration is required. All you need is a fast and stable internet connection.

VoIP apps use the Session Initiation Protocol (or SIP) as an underlying technology.

Let’s figure out what it is that you’re missing if you’re not using one of the best VoIP apps out there. The most admired benefits of using a VoIP app are as follows:

  • User-Friendly: VoIP apps can easily be installed on any device such as smartphones, tablets, and even laptops or desktops. The main reason VoIP apps have become popular is because of their simplicity in usage and robust features. Some VoIP apps may even remember and save your SIP credentials on your device so that you don’t have to enter them again.
  • Feature-Rich: Some of the features include multi-level auto attendants, HD call quality, conference calls, visual voicemail, hold music, call forwarding, and more. Any organization can control and configure the VoIP apps through one dashboard only.
  • Flexibility: According to Buffer, one of the main hurdles that people are facing in remote work culture is the lack of communication and collaboration. One of the best assets of VoIP apps that sort out this problem is their multi-platform support feature. Many of these apps allow users to be logged in from multiple devices simultaneously and the data is automatically synced between them.

Now that you have an idea of the basics and benefits of VoIP apps, let’s take a look at some of the most popular ones available in the market.
