We recommend you download and install X-Lite from HERE and it's free

Notice that X-Lite will tell you that no SIP accounts are enabled

Either right-click anywhere on the X-Lite interface or choose the left-centre button at the top

Click on SIP Account Settings

When you see this dialogue box, click Add

Enter your ezyTEL extension information

It should look something like the image below. If it does, click OK

Here you can review your extension information, then click Close

X-Lite will register to our system, and when your extension number shows on-screen, you're ready to make calls!
