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.
oh yes there are some differences! the speaker and the microphone on the 7960 is much better than 7940.
Many thanks for manual how to reset to default.. It´s help me solve problem with speaker.
I tryed it in 7940, it can’t work, press # key not happend anything.
