How do I factory reset a SL4050 telephone ?
Article Id #: 39
Lift the handset and dial the number 255000. 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.
