I am currently working an issue in which an ephone status show "deceased". This particular phone has been "deceased" 3 times in the last 3 months, and no other phone has experienced any issues. This phone is running off a small switch which is getting it's link from a fiber to copper transceiver.
Any thoughts? Or info about why the phone is deceased?
DECEASED status indicates that the connection to the Cisco Unified IP phone was closed because of a keepalive timeout. You have a connectivity problem that needs to be fixed.
Deceased means the phone unregistered due to a keep alive timeout. Unfortunately, it probably means a network problem. I would check cabling, the switches, and everything in between the devices. You might try upgrading the phone firmware, but that is really a shot in the dark.
