To access the web interface of your Yealink T19PN phone, you will need to know the IP address of the unit. This can be found by pressing the tick button on your phone.
The IP address will be displayed on the screen. On a web browser on the same network enter this into the address bar.
You will be prompted for a username and password. If you purchased the phone from Gradwell we will have changed this for you for security reasons - please see this article.
If you did not purchase the phone from Gradwell, the username and password will be admin. Please read this article on why it is important to change this from the default.
