How do I factory reset a SL4050 telephone ?

Lift the handset and dial the number 255*000. Then press "OK" three times.

The telephone will reset itself and reboot. Now you can connect to the telephones's IP-address and port 9999. The login credentials are an empty username and an empty password.

Note: Internet Explorer 7 and some Linux Browsers can not send an empty login/password.
