I am running on a 2821 router, 12.4 IOS code. I have 10 7921G IP phones configured on this device.
They all connect up fine and work for a period of time then go into a Deceased status and stop working.
The WiFi device is none cisco (but not by our doing), everything else is Cisco.
attached is the rtr Configuration. I also put in the 'sh ephone sum' cmd and a debug capture during the time the devices drop or go into the Deceased state.
I have seen others have similiar questions about IP phones going into this state but I have not see the answers to the problems.
