  3. Now point your browser to the web interface of the phone: ‘http://<phone-ip-address>’where is the IP address shown on the phone.
  4. Enter the password of the phone and click login to access the phone’s configuration. For this particular phone, the default password to reach administrator mode is “admin” and the default pin is “0000”An image of the snom M3 web GUI
