Can someone help me here?
is there anyway to generate the unregistered phone details from cucm?
If we have, please share the steps.
RTMT may be able to help you out. Launch RTMT.
Then go to CallManager>Devices>Device Search>Open Device Search>Phone (see below)
Then select "Unregistered", choose your CallManager (or "Any") then choose Next or Finish.
If you choose Next you can further fine tune what gets displayed.
Note that this report focuses on "Unregistered" devices. This means that the device was once registered. If a phone never registered, then it will not show up in this report.
