Configuring a SIP Account in a Softphone App

After signing up with CommPeak and getting your SIP Account credentials, your next step is to register your SIP Account in a softphone application or with your IP phone.

To illustrate the steps required for softphone configuration, we will use Zoiper.


Zoiper is a softphone application available for Windows, macOS and Linux, as well as Android and iOS. This is third-party software, which we are using for illustration only. Instead, you can install any other softphone available for downloading and configure it with your SIP credentials.

  1. Download Zoiper from https://www.zoiper.com/ and install it on your device.

  2. Start Zoiper.

  3. Specify your SIP account credentials in the start window:

  • In the first box, enter the username and domain, separated with @.
    For example: 

  • In the second box, enter the password.

Then click Login.

  1. In the next window you will see that the previously entered domain is filled in the box automatically. Make sure that it is spelled correctly and click Next.

  1. In the next window, click Skip.

  1. Now wait until the program tests possible configuration options.
    When SIP TCP or SIP UDP is marked in green, you can click 
    Next and skip the test for IAX UDP.

  1. Click Configure to test your audio and video, or Skip to proceed without testing.

  1. Click Finish.

Zoiper will open. Now you can make your first call!

To dial a number, click the dialpad icon. Ensure there is a green mark next to your username – it shows that you are connected to the network.
