4612 comming up wrong set type (others are fine)

[bazlit]

I have one of the 4612 stations out of a few comming up wrong set type on boot, i dont seem to be able to find why this is doing it

I've seen this when the extension number that the 46xx phone has previous used, is already allocated to a non-IP extension. Typically when moving phones between systems.

I have a 4612 that I'm trying to change the extension on but when it boots up it says Wrong Set Type and doesn't allow me. The extension I have assigned it in Manager is not used anywhere else. How do I get into the phone to configure the extension?

Thanks,
Chris

Try reseting it - Hold, then type reset - #.

I've tried that put it just beeps with every keypress. When I press # I get the usual * to retry, # to restart.
