Phone with registeration status known

[Syed]

Dear All,

I have a couple IP phones that are showing their registration status as unknown in cucm, so before removing these kind of phones I would like to know when these ones were last registered? I checked in RTMT phone summary but unknown option is not available and unregistered phones’ timestamp shows latest date (i.e 26^th Jun, 2016). How do I make sure that these phones are not in production for long time now?

Thank you in advance
