This article will provide information on the best VoIP apps on macOS and Windows so that you can compare them according to the various features they offer, and make an informed choice as to which is the best one for your requirements, or business interests.

VoIP apps to consider for macOS and Windows


This app is Mac only. Unfortunately, there is not currently a version for PC users. Moreover, it is a type of VoIP softphone that works in connection with an Asterisk PBX. For more advanced softphone users, this might be a more preferable option, particularly if they happen to own an Asterisk IAX account.

Google Hangouts

As crazy as it sounds, you can actually use Hangouts on Mac as well. The integration process is seamless, and it’s also useful if you already own a Gmail account, as the option to call/message, etc, will be constantly available with all the other Google mail features.

Bria 5

Bria 5 (also known as Bria classic, formerly X-Lite) is a softphone app available on desktop or mobile. This app is particularly business-focused, with an emphasis on providing features that help teams to message each other, gain access to integrated file-sharing, screen sharing, and many other features that are useful for day-to-day work.

Zoiper 5

Zoiper is a softphone app that is now in its fifth incarnation (having replaced the previous versions - Zoiper 3, Zoiper Classic, and the Zoiper web apps, which are now defunct).

Zoiper is free for personal calls, but not business calls, although businesses can purchase a business version known as Zoiper 5 Pro, which provides users the ability to run the software on Windows or Mac, together with mobile devices, such as Android or iOS.


Skype provides a VoIP softphone client that users can install on their computer. Moreover, Skype enables you to call other Skype users for free, as well as make voice calls, video calls, and hold conferences with your team.

Download and Setup VOIP-application

A major difference between the Mac version and the Windows version is the fact that you have to pay for some of the services, however, the rates are quite cheap.


No matter which app you use, you still need to purchase a virtual phone number to use it with.
