Problem with 7921 IP phone - goes to Deceased status after a period of time

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.

Phones are un-registering due to keepalive timeouts. Can you setup a PC to perform packet captures between the CME router and AP?

What version of firmware are the 7921s running? Does this happen while roaming or while the phone is stationary?
