A softphone is a piece of software that runs on a desktop computer, tablet or smartphone and allows you to make calls over the Internet, using a VoIP provider. A softphone removes the need for a physical phone base unit or handset, and enables you to make and receive calls – as well as manage contacts – all from the same user interface screen. Conversations can be held via a connected headset, or with a microphone and speakers attached to your computer.

Softphones have numerous advantages over traditional phone setups:

  • No additional hardware costs for desktop handsets
  • All the flexibility and call management options afforded by typical VoIP (Voice over Internet Protocol) services
  • The option to turn smartphones and other mobile devices into business-level communication tools, which can be used out of the office and on the move

Best Softphone Apps

If you already have a business VoIP provider, it's likely that their own softphone app is bundled with your service package. We've included several of the most popular such provider-designed softphone apps below, so if you're already with RingCentral, for example, it would make sense to stick with their app as this will offer optimal integration with your existing phone system.

Alongside these provider softphone platforms, we've also listed several other standalone apps that can be used regardless of which VoIP service you use.

Best Softphone Apps for iPhone and Android

Many softphone apps have iPhone and Android versions available, but it's worth checking before you take the plunge and sign up. It's a good idea to know what equipment your staff have access to and whether or not the app you choose will be compatible with their platform of choice. Not a problem if you provide equipment through the company, but if you're expecting staff to use their own devices, make sure you know what they're using.

On this page, the best softphone apps that work on both Android and iOS include RingCentral, Counterpath Bria, ZoiPer and 3CXPhone.

Some softphone apps are platform specific. It's not too surprising to learn that one of our recommended apps, iSoftPhone, only works on Apple devices, so it's even more important to make sure you're selecting an app that the majority of your staff can use.
