We have some 6120 wireless handsets that occasionally drop calls with a "Watchdog Timeout" error on the screen. After a several seconds, the phone resets and associates with the AP. I've checked the signal strength, and everything seems to be ok there. So does latency and throughput back to the SVPs. This happens occasionally everywhere in our organization, but it's particularly bothersome in an offsite building connected back here through single mode fiber. If anyone knows how to get this error resolved, you'd make my users very happy.
