[cisco-voip] quick sanity check on factory reset

[Nate VanMaren]

It can work for a remote phone if you change the DHCP server’s option 150, instead of manually changing tftp settings on the phone.

Not going to work for a remote phone.

And not going to work for these phones which can’t access the settings any longer.

ok. perhaps the factory default treats an incompatible firmware on the phone differently and requires at minimum the loading of whatever the default firmware is.

as Ed stated, it's pretty easy to get around this by using a local TFTP server. i use pumpkin. a local L3 switch with DHCP server and ip helper address set to the laptop running TFTP server should work well.

if your network doesn't filter TFTP, you can simply set an alternate TFTP server on the phone to point to the laptop.

the laptop with TFTP must have the appropriate files loaded  however.  takes a bit of time to work out, but once setup, you have it for future requirements.

They keep on showing the Cisco logo and doing nothing.  Can’t press any buttons it just stops working.

I got the auth failed once.  Now when I try again it says it’s upgrading term06.default then the cisco logo and kaput.

Sending traces off to TAC now.

The phones may not be able to upgrade without the bridge software loaded first, but this shouldn't brick them. They should just continue using the old firmware. That has been my experience. Weird.

That’s kind of the line of thought I was having.

The phones have addresses in the scope and were registered at one time.  Trying the factory reset from 8.3(2) to 9.0(3) in order to avoid the ‘bridge’ firmware upgrade.  Not a big deal for the new ones we ordered but we have a handful which are 3+ years old and never taken out of the box.

Which version was the bridge to the newer signature files, I thought it was it 8.3.3? Only thing I can think of offhand is to be careful of that. I had someone do a factory reset on a phone running older firmware and it would not load the default from our live CUCM tftp server (version 9.2.1ish). I had to get it upgraded from a separate TFTP to the bridge version - kinda surprised I thought the factory reset would have wiped everything and caused it to accept any firmware.

This should factory reset without issue, correct?
