[cisco-voip] Does anyone know how long it takes a phone that has been disconnected from CUCM to change from an unregistered status to an unknown status?

[Matthew Berry]

I believe you're correct in that assumption.  As long as the phone has registered during the current "uptime session" of the CUCM, the IP address is cached in the system.

Thanks!

I thought I had read something along the lines of phones only show up as unknown if they had never registered to CUCM during the current cluster uptime. Basically only a full reboot would put an unregistered phone to unknown. I don’t remember where I read this and I could be totally wrong so don’t hold me to it, but if I’m close to right hopefully it might jog someone else’s memory of the complete answer.

Hi All,

Does anyone know how long it takes a phone that has been disconnected from CUCM to change from an unregistered status to an unknown status?

Regards
Simon
