I bought a Cisco 7912 phone second hand. I am trying to configure it, but I am unable to enter the "Network Configuration" item from the settings menu. That is, when I highlight it and press the "Select" softkey on it, absolutely nothing happens. I can enter all the other menu items, so I figured it has been locked out somehow.
**# (as mentioned in the manual) does nothing. I gather the **# is for unlocking items within the Network Configuration menu, but I can't even enter it.
I have tried factory reset softkey from the menu, and this does respond at all. I can't connect to the phone through the web interface, as I can't configure the phone to connect to my network.
I have no idea what to do. Please note I have no experience with IP phones, I just bought it to use my home VOIP service.
Any help would be greatly appreciated.
You may try to factory reset the phone by pressing the menu button and then press **2. It will ask you if you want to perform factory reset and you should confirm.
