A softphone, or software phone, is an app that runs on internet-connected devices (computers, smartphones, etc.) to make calls, video chat, and exchange messages. They come in several types (UCaaS suites, business-grade softphones, simple dialers, white-label platforms, residential options, open-source, and mobile-first).
Pricing ranges from free to enterprise plans, and key features often include call logs, voicemail, CRM integrations, and encryption. Overall, softphones help cut costs, reduce hardware needs, and offer flexible, scalable communication for businesses and individuals alike.
Business communication has transformed dramatically over recent decades. Traditional desk phones with physical buttons and dedicated lines once dominated offices—reliable but expensive, difficult to scale, and limiting mobility.
The arrival of VoIP in the late 1990s marked a key shift, allowing voice data to travel over the internet rather than dedicated phone lines. Early softphones emerged in the early 2000s as simple computer applications for internet calling, though they initially suffered from quality issues.
As internet speeds improved and smartphones became ubiquitous, softphones evolved into sophisticated communication tools. Today’s versions deliver enterprise-grade capabilities across any internet-connected device, effectively replacing dedicated phone hardware with flexible, scalable software solutions.
A softphone is software app that turns your internet-connected device into a fully functional phone. The term combines “software” and “telephone,” reflecting its nature as a digital alternative to physical phone hardware.
These applications run on smartphones, tablets, laptops, or desktop computers, enabling voice and video calls, messaging, and collaboration through your internet connection rather than traditional phone lines.
Modern softphones connect to VoIP (Voice over Internet Protocol) services, transforming digital data packets into the voice communications you hear. This technology powers everything from basic calling apps to comprehensive business communication platforms that integrate with customer relationship management systems and other business tools.
Where traditional desk phones require dedicated hardware, physical connections, and often separate infrastructure, softphones leverage existing devices and internet connectivity. This fundamental difference creates several key distinctions:
Think of softphones as the digital evolution of desk phones. They turn your existing devices into business phones, letting you make calls from anywhere with internet. For a full breakdown, check our softphone vs hardphones rundown.
Softphones convert your voice into digital packets that travel over the internet. When you speak, the app digitizes your voice, compresses it, and sends these packets to your VoIP provider’s servers, which route them to your recipient.
Most of this technology is powered by the Session Initiation Protocol, which we took some time to explain in our complete guide to SIP.
For calls to traditional numbers, the provider translates digital signals to analog format (a.k.a SIP trunking). The entire process happens in milliseconds, creating seamless conversations.
Despite the complex technology, softphones offer intuitive interfaces similar to traditional phone apps. You’ll find the familiar dial pad, call history, and contacts, alongside modern additions like presence indicators and integrated messaging.
This design makes the transition nearly effortless—most users can start making calls immediately without a learning curve, whether on desktop or mobile.
Your softphone connects to a VoIP service provider that routes your calls and manages your phone numbers. Just like mobile carriers offer plans with specific minute allowances or unlimited calling, VoIP providers offer similar subscription plans for your business or personal communications.
Setup typically involves entering your SIP credentials (another buzzword for communication via the internet) into the app, which authenticates your connection and links to your business phone number.
Once configured, the app maintains this connection in the background, handling technical complexities automatically so you can focus on communication.
Now that we understand what softphones are, let’s explore the main types you’ll encounter. Just like cars come in sedans, SUVs, and trucks, softphones have their own categories to suit different business needs.
Business VoIP softphones provide reliable voice communication for professional environments. These applications focus on delivering traditional phone system functionality with digital advantages.
Products like CounterPath’s Bria offer robust features despite their somewhat dated interface. Alternatively, solutions like the Generic Cloud Softphone App offer similar functionality with modern interface options, available in tiered packages from basic outbound-only calling to full-featured enterprise solutions with video conferencing capabilities.
These solutions are particularly well-suited for businesses transitioning from legacy phone systems that need reliable voice communication without the full complexity of comprehensive unified communications platforms.
White-label softphones offer a completely branded communication experience. These platforms allow businesses to create custom-branded apps with their own logo, colors, and user experience—essential for communication service providers or enterprises wanting to maintain brand consistency or resell telco solutions.
Acrobits Cloud Softphone exemplifies this category with over 300 customization options. This flexibility allows businesses to create communication solutions perfectly aligned with their brand and workflow requirements, from simple calling interfaces to comprehensive collaboration tools.

Softphones in larger Unified Communications as a Service (UCaaS) suites are parts of broader, integrated communication ecosystems. These aren’t standalone applications, but tools inside enterprise platforms.
In popular UCaaS suites like those offered by RingCentral, Nextiva, or Microsoft Teams — softphone functionality is added into a broader tapestry of communication tools. These softphones serve as the voice and video calling interface within a much larger system.
UCaaS-based softphones are best for medium to large enterprises requiring a holistic communication solution, such as big call centers. They excel in providing a unified experience where voice calls are just one part of a multi-faceted communication strategy.

These apps excel in providing a full-featured softphone experience optimized for mobile devices, ensuring employees can stay connected wherever they are.
Beyond the main categories, several specialized softphone types serve specific needs in the communication landscape.
Each of these alternatives addresses specific use cases where the mainstream softphone categories might not be the perfect fit. Organizations with unique requirements or budget constraints may find these options provide more tailored solutions while still delivering the core benefits of softphone technology.
With the types of softphones clear, what about the actual capabilities that make them worth using? Let’s look at the features that give softphones their real-world value.
Modern softphones provide advanced calling features that help manage business communications efficiently while maintaining professional caller experiences.
Integrated messaging capabilities allow text-based communication and file exchange directly within the softphone application.
Video capabilities enable face-to-face meetings regardless of participant locations. Users can transition from voice calls to video with screen sharing options, accommodating both planned meetings and spontaneous visual collaboration.
Advanced video features include recording capabilities, virtual backgrounds for privacy, and participant management tools that control who can join and what they can share during sessions.
Beyond basic communication tools, modern softphones offer sophisticated capabilities that enhance business operations. Contact management centralizes customer information, call analytics provide insights into communication patterns, and advanced voicemail features streamline message handling.
These tools integrate with business processes to improve efficiency and customer service. Users can access detailed call history, customize voicemail greetings by time of day, and synchronize contacts across devices—all contributing to more professional and responsive business communications.
For power users and businesses with complex needs, softphones offer advanced integration and security capabilities that elevate their functionality.
Integration Capabilities: Modern softphones connect with business tools through CRM integrations that display customer information during calls and log interactions automatically.
API support allows developers to create custom connections with internal systems, extending functionality to match specific workflows.
Security Features: Enterprise-grade softphones provide communication security through encryption that protects calls and messages. Authentication options like multi-factor verification and single sign-on ensure only authorized users access your business communications while maintaining regulatory compliance.
Technical features aside, what’s the bottom line for businesses? Let’s explore the practical reasons organizations are embracing softphones in their day-to-day operations.
Companies typically reduce phone costs by 40-60% when switching to softphones. Without expensive hardware to purchase and maintain, businesses save on equipment, installation, and ongoing maintenance. Startups can slash communication costs by up to 90% by avoiding traditional phone infrastructure entirely.
Softphones untether your team from physical desks. Whether responding to customer calls from home or taking meetings while visiting clients, your phone number and capabilities travel with you. This mobility remains valuable in our hybrid work world.
With softphones, onboarding new team members takes minutes—just create an account, share login credentials, and they’re connected. This scalability works both ways; you can easily adjust capacity during seasonal fluctuations.
Softphones help maintain boundaries between personal and professional life, even on the same device. Team members can handle business calls without sharing personal numbers, and can set business hours when calls automatically route to voicemail.
While Microsoft Teams is popular, many organizations need alternatives. Some find Teams overly complex or expensive for simple calling needs. Others require different compliance capabilities or prefer streamlined interfaces focused on voice communication.
White-label softphones serve multiple needs: service providers can resell branded communication solutions, businesses can offer apps with their own logos and colors, and organizations can create custom communication suites tailored exactly to their workflow—all maintaining consistent brand identity at every touchpoint.

Softphones can be either free or paid depending on the features and services needed. Free softphones typically offer basic functionalities suitable for personal or limited professional use.
A primary disadvantage of softphones is their dependency on a stable internet connection.
Softphone applications cannot function without internet access, limiting communication capability, particularly in areas with poor connectivity.
This reliance poses a challenge for users when consistent, high-quality internet service is not guaranteed.
A softphone is a software-based component of VoIP technology, allowing users to make calls over the Internet from a computer or mobile.
While VoIP is the broader system that also includes hardphones, a softphone specifically refers to the application that enables VoIP calls.
It is called a “softphone” because it is software-based rather than a tangible (‘hard’) device like a traditional phone.
“Soft,” short for “software,” signifies that the phone functions are provided through an application running on a computer or mobile device, utilizing internet protocol (IP) for communication.
No, softphones are no more complicated to install than any other application, both in desktop and mobile.
Fortunately, the requirements and limitations are quite minimal:
To use a softphone you will need a softphone app, an internet connection, and a VoIP SIP account.
Most free softphone apps still need a connection to VoIP service providers for the minutes and the phone number, which comes with a cost.
Headsets are recommended for softphone usage to guarantee the highest quality telephone calls. You can also use speakers and a microphone as alternatives, but that can result in the microphone picking up the voice coming out of the speakers.
A softphone is a piece of software, so it looks quite similar to any other app that can make phone calls now. Additionally, early softphones were designed to mimic hardware phones, so there is plenty of overlap between how they look and feel — even if one is software and the other isn’t.
Whether on desktop or mobile, unified provisioning and authentication are critical to creating a positive user experience. This is even more true when an app is the sole interface between a customer and a service provider. For users: Unified systems provide a single, intuitive authentication flow, eliminating the need for multiple logins. This makes it […]
