VoIP App 101: Simple Answers to ALL Your Questions About Them

A VoIP app is more common today than it has ever been before. Chances are even if you don’t know what a VoIP app is you’ve already used one.

From enterprise corporations to small businesses, many have adopted SIP (Session Initiation Protocol)-based VoIP capabilities that give employees a feature-rich communications solution manageable from one central location — a VoIP application.

Instead of a desk phone, businesses can enable their teams to work remotely with nothing more than an app.

With that in mind, let’s talk about what VoIP means for your small business. Firstly, we’ll cover what a VoIP app is and how it can improve your business communications. Secondly, we’ll take a look at some of the most popular VoIP applications and what they have to offer.

Moreover, we’ll give you all the information you need to set your business up for success and help you choose the best VoIP app for your needs.

What is a VoIP App?

VoIP (Voice over Internet Protocol) is a way to make telephony calls over an existing internet connection via the cloud. A VoIP app lets you make calls, send texts and more with VoIP technology.

With a VoIP solution users no longer need to rely on a hard phone line or their mobile data plans to make calls, conduct video conferences, or access collaboration tools. To put it simply, VoIP is video, text, or voice communication conducted over the internet.

In fact, experts believe that VoIP solutions will eventually replace all forms of traditional phone services. This is thanks to VoIP’s flexibility, low-cost options, and the ability to help improve productivity and customer-facing communication.

For instance, if you’ve ever used an application like Skype or WhatsApp, you’ve already experienced the power of VoIP apps and their ability to allow you to administer a conference call or send a text message over WiFi.

The simplicity of VoIP apps and their wide availability are what make them so attractive to businesses all over the world. While employees are continuing to move to a work-from-home format and remote offices are popping up everywhere, it’s no surprise that VoIP solutions are growing in popularity.

Benefits of a VoIP App: Why You Need Them in the First Place

1) Ease of Use

VoIP App: Nextiva App Play Store

Implementing a new unified communication solution office-wide is a huge responsibility, both financially and on your technology team. As a result, VoIP apps have become popular due to their simple set-up and ease of use.

All you have to do is download an app to your Android or iOS device, go through the sign-up process, and begin using it. These days WiFi and mobile signals are widely available everywhere, so as long as you have access to one of those you’re good to go.

2) Cost Effective

Another reason businesses are looking to VoIP as their next great unified communication solution is because of the cost savings. VoIP apps for individual use are often completely free to users. However, companies can subscribe to an all-in-one solution and utilize the app as part of their VoIP service.

For businesses, these VoIP plans tend to be much less costly both in implementation and monthly fees than communication solutions have been in the past.

3) Flexibility

VoIP apps can go anywhere with you, hence why they’ve grown more popular with the rise of the remote worker. From your laptop, tablet, or mobile device, you can easily access your business line and use it whenever and wherever you need. VoIP simplifies features like call forwarding, voicemail, and presence to bring your office right to the palm of your hand.

For employees, this means they no longer have to use their personal numbers or mobile data to do business while away from the office.

For many businesses, VoIP apps have helped them take their communication strategy into the modern age and offer employees more options.

3) Zoiper Softphone

Zoiper is a VoIP and SIP android app that focuses on providing outstanding softphone services. The reason Zoiper is successful is due to its excellent call quality even when done over a shoddy internet connection.

VoIP App for iOS

1) Nextiva App

2) Skype

Skype is a well-known application for both business and individual use. This Microsoft owned program has been widely available for some time, which means that it’s likely any of your business partners will have an account.

3) WhatsApp

Initially a favorite VoIP app outside of the United States, WhatsApp has recently started to grow a presence as a text and video call solution for travelers.

Its lack of options for group and conference calling has prevented it from catching on with enterprise and business accounts, but it still continues to grow thanks to its user-base.

Additional concerns users have with WhatsApp is that it’s a Facebook-owned platform which raises the question of privacy concerns.
