I bought a used Cisco 7960 phone. When I started configuring it, I got in to problem when it didn’t let me modify the configuration because I never know the password. So i tried to find that how can i reset Cisco 7960 default factory. At the end I found the following solution which I’m going to share.
Simply hold down the # key while you power-cycle the phone. (If you already have the SIP firmware loaded, simply press * and 6 and Settings at the same time, and the phone will reboot. Then press and hold the # key while it boots.)
After a second or two, the phone display will say:
Reset key sequence detected
The headset, mute, and speakerphone lights will cycle. Now, simply press the following keys:
1 2 3 4 5 6 7 8 9 * 0 #
Now, the phone will ask you whether or not you want to save your network configuration. I usually press 2 for no.
Save network cfg? 1=yes 2=no
The display will then say:
Factory reset initiated
and the phone will continue to boot. There you have it a quick and easy way to do a factory reset.
There is no difference between Cisco 7940 and 7960. The only difference I can see is 7940 has two lines/buttons and 7960 phone has 6 lines/button. You can use same SIP version on both models with all same configurations.
