Best Softphone Apps For Businesses in 2025

Are you looking for flexible communication tools? 

‍

Do you want to align your communication channels with your workflows? 

‍

Then you're in the right place. 

‍

In this article, we explain what softphones are, their benefits and which softphone app you should pick for your business. 

What is a Softphone? 

Quick definition

A softphone is a software application that allows users to make phone calls over the internet using a computer or mobile device, instead of a physical phone line. It leverages Voice over Internet Protocol (VoIP) technology, offering flexibility, mobility, and cost efficiency. 

How does the technology behind a softphone work?

Traditional landlines use cables or phone networks to connect your call, it is literally like having a direct line between two phones.

Softphones, on the other hand, don’t need any of that. They use the internet to send your voice, just like sending a message or watching a video online. Your voice is turned into small bits of data, sent across the internet, and reassembled on the other side.

To keep your call private, softphones wrap your voice in a digital “envelope” that only the person you're calling can open. That means no one can listen in, even if you're on public Wi-Fi.

Simple, fast, and secure. That’s how softphones make calling work without phone lines.

Is a Softphone the Same as a Desk Phone?

A softphone goes beyond replicating the functions of a desk phone. 

Why? 

When working from a computer or smartphone, you'll benefit from additional features such as:

• Smart call forwarding
• Multi-line support (aka a second phone number)
• Voicemail transcription
• AI receptionist
• etc.

You can also work on the go, or outside your office or home.

Great, isn't it?

Why Use a Softphone? 

Softphones come with various benefits that convince more and more companies to switch.

No wonder why from 2010 to 2018, VoIP subscriptions more than tripled.
‍

Here are some of the benefits. 

Cost Efficiency

Softphones dramatically cut communication costs by using VoIP, eliminating expensive hardware, and reducing call charges, especially for international communications.

Traditional phones required:

• A dedicated subscription,
• A hardware phone,
• And the setup costs.

Softphones only require an Internet connection and a subscription to a VOIP service like Allô.

Enhanced Mobility

Employees can handle calls from anywhere using a softphone app, allowing you to work remotely.

Easy Integration

Modern softphone software integrates seamlessly with CRM platforms, email systems, and other business tools, streamlining workflows and boosting productivity.

Advanced Features

From automatic call recording and voicemail transcription to intelligent call routing, softphone systems provide features far beyond traditional phone lines.
