If you decide that you want to use another softphone other that X-Lite, we suggest Zoiper.
You can download it here and it should automatically detect your operating system (Windows or Mac).
There is also an Android App that you can use.
After clicking on Settings, you will need to click on "Create a new Account"
Once you click on "Create a new Account" you will see a pop up asking you to select what type of account. Choose SIP and then click Next.
Next, you will need to place the SIP information in Zoiper.
This information can be found in the Agent's Settings Tab.
Once that information has been placed in Zoiper, click on Next.
To ensure that your Zoiper device settings are correct, click here.
