The reset button on the snom ONE serves two purposes: First of all, it is a way to reboot the system without disconnecting the power. In order to do, push the button (and release it quickly after the pushing). The LED on the box will start blinking fast and then after 4 seconds start rebooting. Secondly, you can use the button to factory reset the system. After pushing the button, wait until the LED starts blinking fast. During the fast blinking period (about 4 seconds), you have to push the button three more times. Then after the blinking is over, the system will detect that a factory reset is desired and execute it.
this I have tried and it does not Work...
other solution would be to ssh into the unit..
how can it without the password?
