Activating the Zoiper License: (Zoiper Business Edition Only)

If you are using Zoiper Business Edition, an activation screen will appear on the first startup. Please fill in the email address you used to purchase Zoiper as the 'username field'. You can find the password in the mail that was sent to you directly after your purchase.

Activate online

If your computer is connected to the Internet, you can activate your copy of Zoiper automatically by clicking on the Activate online button. Zoiper will contact our licensing server and download the needed license files.

If your computer requires the use of a manually configured http proxy server, zoiper will automatically use the proxy as configured in the mac os X preferences.

Activate offline

If your computer is not connected to the Internet or a firewall is blocking access to our licensing server, the “Activate offline” - button can be used. Clicking on the button will generate a file that contains some details that are unique for your computer and the version of Zoiper that you are trying to register. The filename contains the name of your computer. It will look like this:

Open your file browser (Finder);

Select Go -> Go to Location and open this location:

Send an email with the PCNAME.certificate file attached to [email protected];

Close the instructions window.

Our server will send you a file named certificate. Please place it next to the PCNAME.certificate file and start your Zoiper. Note that the certificate file needs no extension.

Silent installers for mass deployments.

If you would like to install Zoiper without the need for user interaction, but with a progress indicator, use these command line options to the zoiper installer. (You will need to adjust the name based on the installer you are using).

Activation errors

In case the username and or password is incorrect, an error message will be shown and the application will exit. Please restart the application and try again.

If all went fine, this notice should appear, you are now ready to use the application

Configure Microphone and Speaker

Zoiper comes with a built-in Audio Wizard for easy configuration of your microphone and Speaker.

You may access this Audio Wizard by:

  • Clicking on the speaker icon on the bottom right
  • Clicking on the Settings menu in Zoiper and selecting Audio Wizard

Zoiper will configure your Speakers first.

Click on the “start the test” – button.

If your speakers are configured and connected properly, you should hear a ringing sound. If you do, please click on the Yes button and move on to the Microphone step.

If no ringing sound was heard, please make sure your speakers are connected properly and powered on and if needed change the selected audio device on the bottom of the page to a different one and try again by clicking on the “no” – button.

Click on the “Test your microphone” – button to start recording your voice.

If the selected microphone is connected properly, you should see the volume meter move when speaking into the microphone. If the volume meter is not moving, please check your cabling and make sure the proper audio device is selected in the Device section on the bottom of the page.

Configuring a SIP, IAX or XMPP account

Now that the audio devices are configured, it is time to move on to the configuration of the server you want to use. This could be a VoIP provider, your office PBX or a public XMPP provider such as Facebook.

Click on the Settings menu and select “create a new account”.

Account Type

A new page will appear to select the type of account you want to make. This will usually be SIP, unless your VoIP provider or system administrator instructed you otherwise

Select the type of account you want to configure and click on the “Next” – button.

Tip: Please visit for more information on how to make things easier for your users by providing them with a preconfigured or preprovisioned Zoiper. This will bypass all tedious configuration tasks for the end user and will allow the user to make calls immediately after the installation.


Your provider or system administrator should have provided you with a username, password and possibly a hostname.

Fill in the username on the first line and the password on the second line.

If your administrator provider you with a domain, proxy, registrar, hostname, outbound proxy or server field, please fill enter it on the last line.

Fill in the username on the first line and the password on the second line. The username could look like:




The password will typically be a random string, usually with a combination of lowercase and uppercase characters and some number like:

This field will typically look like:


or in case of a PBX might look like:

Account name

Please enter a name to identify this account; you are free to give it any name of your liking.

When you are done, click on the “next” – button. Zoiper will now try to figure out the best way to connect to the VOIP server.


In case the account wizard is unable to automatically configure your account, this could be due to a variety of reasons.

Most common reasons are:

  • The server hostname does not exist or is incorrect.
  • The username or password is incorrect.
  • The server is not responding or a firewall is blocking the access.
  • The account needs additional configuration to register

Please verify the information you have entered and try again.

If you are sure the information are correct and want to save the information and want to complete the configuration manually, click on “I know what I am doing, save this information anyway”.

Find the best softphone app for your business

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 business 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

Below, we round up the best softphone apps available in 2020, including their key features and pricing.

To cut to the chase and compare prices and suppliers matched to your specific requirements, use our free quotes tool to find bespoke quotes for your business.

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.

With this selection of softphone apps, we're confident that you’ll find exactly the right solution for your requirements – whether you’re a solo entrepreneur, a small business, or a larger enterprise.

Best Softphone Apps:


The RingCentral softphone application is the best choice for businesses looking for streamlined and long term growth. The app is free if RingCentral is already your VoIP provider. If not, you'll need to sign up to one of four packages– Entry, Standard, Premium or Enterprise – to take advantage of the app's benefits.

Ringcentral's app operates on Windows, Mac, iOS and Android, and provides a wide range of industry-leading VoIP communication features which make it worth the investment, including video calling, messaging, screen-sharing and virtual whiteboards.

The high call quality and wide-ranging functionality will significantly improve your communication and collaboration, especially given the app has recently been updated (May 2020) to replace the former “RC phone” and provide even better user experience.

Price: from $19.99/month

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.
