To manually add your extension to a phone, you will need some information from us first. Then, follow the steps below.

First, press the up arrow on the phone. It will show the phone's IP address. You will need to log in to the phone. Look for the IPv4 address. Usually, it will be 192.168.X.X if you're on Bell or 10.0.0.X if you're on Rogers. Note that your IP might be different. It just depends on the router you are using. 

In the example below, the phone IP is 192.168.11.158.

Open up Chrome, Firefox or Edge and type the phone's IP in the address bar, not the search box below.

Press enter then you'll see this screen.
