I have a 524SG phone that was working, in default, waiting for me to customize. We plugged it in and it got an extension. Now there is no ephone or ephone-dn with the phones information or any evidence that it ever registered at all.
How can I get this phone back?
What troubleshooting steps can I try?
What cli debugs will tell me issues with phone registration?
I tried the phone debug in CCA but it only shows debug info for registered phones.
