[cisco-voip] 8941 SCCP 9.2.3.5 on 8.6 - One suddenly going Phone Not Registered

[Ed Leatherman]

I would definitely rule out a physical or switch issue first. Might be
something as simple as a loose RJ45 connector causing the phone to drop and
when she reinserts it, it makes contact again.

I believe you can look for "Last=" in the phone status logs or in CUCM
syslog for that device and see a reason code which may help. If that is the
only phone that is exhibiting this behavior, it seems like investigating
local to the phone might be the best approach initially.
