I am not able to perform a factory reset on a Cisco IP Phone 7940G with SIP.
The password for the "unlock config" got lost! Tried also the default "cisco". The 7940G got configured by a coworker, who left the company.
Allready I tried with pressing "*+ 6 + Settings" and holding down # before the headset led starts blinking, but the option for a reset will not be shown.
Please provide a solution for a factory reset
