7 Best VoIP Software for Windows & Mobiles 2025 | Paid & Free Voice Over IP Calling App
In this article, we did an in-depth review of the best Free & Business VoIP software for desktop & mobile available in the market, comparing their features and pricing to help you select the right tool for your needs.
VoIP (Voice over Internet Protocol) software lets users make voice calls online. Businesses widely use this technology due to its advanced features and scalability while also providing cost savings.
VoIP software can be categorized into two types: hard phones and soft phones. Hard phones are physical devices that connect to the internet, while softphones are software applications installed on computers, smartphones, and tablets. 
What is VoIP Software?
VoIP software is a communication technology that allows users to make voice, video calls, and send messages over the internet. Businesses commonly use it to save money on phone bills and improve communication with remote workers and customers.
How does VoIP Software Work on Mobile & Pc?
To use VoIP software on mobile or PC, users need a reliable internet connection and a compatible device with a microphone and speaker. They can then install a softphone app, enter their VoIP account credentials, and start making calls over the internet.
How to Choose VoIP Application?
VoIP software selection depends on Business size, features, and pricing plan.
- Selecting VoIP Software by budget
To choose the right pricing plan for your company's VoIP service, gather information about the number of employees, inbound call volume, and international calling needs. This data will help you determine which plan best fits your budget and requirements.
2. Choosing a VoIP application by business size.
Small businesses may benefit from a simpler and more affordable solution, while larger businesses may require more advanced features and scalability. It is important to consider factors like call volume, budget, and the need for integrations when selecting a VoIP application.
3. VoIP application by Feature
When selecting VoIP software for your business, it's important to list the features that meet your specific requirements. This will help you narrow your search and find a solution that meets your needs. Consider features like call routing, conference calling, voicemail-to-email, and integration with other business tools.
4.
Choosing VoIP Software by scalability
It is important to consider potential future needs. Here are some key factors in evaluating:
- Do you anticipate needing phone trees (automated menus) for callers to navigate?
- Will an IVR (interactive voice response) system be necessary to handle large call volumes or complex call routing?
- How many extensions will be needed to accommodate current and future staff?
- Is the software flexible enough to expand easily as your organization grows?
- Does the software offer mobile apps to support remote work and mobile users?
Considering these factors can help you select VoIP software that will meet your current and future needs.
5. Additional points to select Voice Over IP Software
When selecting a VoIP software solution for your business, here are some additional considerations to keep in mind:
- Customer support: Training materials and responsive technical support.
- Security measures: Ensure the VoIP software uses strong encryption to protect calls from eavesdropping and hacking.
- Third-party integration and UCaaS: Check whether the software integrates with your other tools, such as your CRM or marketing automation platform.
