Sean,

The two codes for it, are to hold the pound key when powering it on.

When the line keys flash, key go of pound and enter: 123456789*0# , which should erase the configuration.

If you observe that it is still showing internal information, try 3491672850*# , which in my experience rips it down to a bootstrap, but, I've never loaded the term default on it to see if there's anything left by the time it recovers.

Best,

Adam

Subject: [cisco-voip] 7900 Factory Reset w/out connecting to the network

We are finally refreshing our 7970's. We wanted to factory reset the old phones before sending out for scrap. Is there a way to factory reset without having to connect to the network?

Thanks.

Sean.

Adam, I've always been under the impression that either of these options
require DHCP Option 150 with a working TFTP and files to work properly.
Are you saying they don't? I've never tested it though.

No DHCP is needed, don't even need a live network to reset, just need power

you only need option 150 if you want it to try and update firmware, and of
course, it needs a phone config on CUCM to do that

for what a 7970 is worth as trade in or resell, it's too much work, a
hammer works better/faster :)

I had assumed the working state of the phone when finished wasn’t important here given scrapping them out.

Otherwise the second one will leave you with a bad time if you’re not setup to repair the phone when you do that. The first one shouldn’t but its been a long time since I’ve been near one of these to know if it retains any last good configuration
