How to Connect VoIP Phone to Computer: A Step-by-Step Guide

In this article, we’ll show you how to connect your VoIP phone to your computer using an ethernet cable, and then share the internet connection from your computer to the phone.

First, it’s important to note that an iPhone is different from a standard landline phone. Even though they may look the same, an iPhone uses the internet connection to make phone calls instead of the phone line. This is important to know if you’re moving to a new location or changing your phone service provider.

So, if you’re in a situation where you need to connect your VoIP phone to your computer, whether it’s for business or home use, follow these simple steps:

Step 1: Connect the Cable

Physically connect the ethernet cable to your computer, and connect the other end to your phone. Be sure to plug the cable into the correct port, which is the internet port on the back of the phone.

Step 2: Set Up the Computer

Verify that your computer is connected to the internet via Wi-Fi. Go to the Control Panel, then Network and Internet, and click on Network Connections. You should see the Wi-Fi connection you’re using, as well as the Ethernet connection between the phone and the computer.

Next, go to the Ethernet connection’s IP settings, and make sure it is set to automatic. Then, go to the Sharing tab, and click on the box to allow sharing.

Now, go back to the Wi-Fi connection, and click on Properties. Tick the box to allow sharing, but don’t change anything else.

Finally, change the IP DNS settings to, and click OK.

Step 3: Test the Connection

Now that everything is set up, it’s time to test the connection. On your VoIP phone, go to the basic settings and update the configuration. Then, go back to the home screen and check that the phone is connected to the internet.

To test the phone, make a call to a random number. If everything is working properly, you should hear a dial tone and be able to make the call.


Connecting your VoIP phone to your computer is an easy way to keep your existing landline number, and it’s more convenient than using a mobile-sized cordless device. Just follow these simple steps to set it up, and you’ll be able to make calls using your VoIP phone in no time.
