More businesses are now switching to VoIP apps, replacing traditional phone lines and desk phones.
VoIP provides low-cost voice and video calls globally through data. As VoIP apps improve, they’re quickly changing how modern businesses communicate.
But with several apps flooding the market, it gets tricky to know the right one for your business and how you choose it.
In this article, we’ll talk about the benefits of VoIP apps, the best VoIP apps to consider, and the features to look for in a VoIP phone service — whether switching to VoIP or using an existing solution.
What Is a VoIP App?
VoIP apps, also known as softphones, are software applications that transmit voice and video data over the internet, instead of traditional phone networks.
A VoIP app runs on the Voice over Internet Protocol technology, transmitting voice packets over the internet for clear calls. They cater to enterprises and small businesses alike for low-cost communications.
Chances are you’ve already used one before. Popular personal VoIP apps include Skype, Viber, and WhatsApp.
It’s easy to install VoIP apps on a computer or smartphone and can be used from anywhere in the world with a stable internet connection.
VoIP apps provide businesses with better phone service for much less, with dozens of premium features, like video conferencing, instant messaging, and even faxing, built into the platform.
Benefits of Using VoIP Apps
VoIP apps offer a variety of benefits that attract many companies, from startups to large enterprises for business communication.
1) Ease of use
Traditional phone systems require complex installation and extensive technical expertise. In contrast, VoIP apps are straightforward to set up. Even non-technical users can quickly get up and running. They work on both mobile and desktop (installed as a desktop app or through web browsers).
Simply download the application, provide your SIP credentials, and you’re ready to make calls. No hardware installation, tangled wires, or lengthy configurations. Wi-Fi and high-speed cellular networks further allow you to seamlessly connect and make calls from virtually anywhere.
For power users seeking advanced features or compatibility with third-party applications, VoIP apps like Nextiva provide a user-friendly experience that eliminates the complexities associated with traditional phone systems.
2) Mobility & accessibility
VoIP apps can go anywhere with you. They’ve grown more popular with the rise of remote workers.
From your laptop, tablet, or cell phone, you can instantly access your business line and use it whenever and wherever you need. Even simple features like ringing multiple devices at once let employees take business calls anywhere.
Rather than changing your workflow for a VoIP app, administrators can fine-tune them to fit your business needs. VoIP apps complement your virtual phone service. It’s a perfect tool to bring your remote teams closer.
3) Unified Communications
VoIP apps easily integrate with other communication channels (SMS, video conferencing, and file sharing), creating a unified communication hub. This lets you scale VoIP to meet your business needs accommodating new users and additional features without costly hardware upgrades.
Centralized management capabilities allow business owners and IT managers to monitor all communication channels and settings through a single interface. This streamlines management, ensures consistent configurations, and simplifies troubleshooting.
You initiate and manage calls from one interface. No more juggling between different communication channels means simplified workflows and lower costs for managing different systems.

Features to Look for in a VoIP App
Call quality
When choosing a VoIP app, call quality is a top priority.
Voice and video quality varies significantly depending on both the app itself and the speed or stability of your internet connection.
Dropped calls, video delays, and poor audio quality negatively impact the user experience. Test call quality under different network conditions to determine whether an app’s performance meets your standards. Nextiva’s VoIP speed test is a good place to start testing your connection’s capacity.
It’s important to assess whether call quality issues are related to the application or just the network environment before moving on to another option.
Nextiva, for instance, has a highly reliable network with 8 points of presence and carrier-grade data centers. We strive for 99.999% uptime so you’ll never miss a beat with your customers.
Cost
VoIP cost depends on your usage. While the basic versions of most VoIP apps are free, some have paid premium versions with additional features.
Evaluate whether the free app’s features meet your needs or whether upgrading to paid versions is worth it for you.
Compare pricing models across different apps to determine the most economical options. Also, look into ways to reduce any broadband data overage charges due to increased calls over internet data.
Cross-platform availability
Cross-platform availability makes a VoIP app infinitely more useful.
VoIP apps such as Nextiva can be accessed via the iOS and Android mobile operating systems as well as directly via desktop browsers. This enables flexible calling from smartphones, tablets, laptops, and computers using the same account.
Consider compatibility requirements before choosing a VoIP provider.
Encryption & security
Encryption and adherence to security best practices impact VoIP app evaluations. End-to-end encryption prevents third parties from accessing call streams, ensuring maximum privacy.
Before transmitting sensitive communications, check the providers’ encryption specifications and security standards. Verify that privacy practices meet expectations.
Advanced features & add-ons
Explore what extra features each VoIP app offers.
Capacity for group video calls, chat tools, call recording permissions, virtual backgrounds, and integrations with other productivity suites vary widely. Weigh which VoIP features are essential versus unnecessary for your use cases.
Compare apps holistically to choose a provider tailored to your needs.
