We purchased several 8821s to start replacing our aging fleet of 7925G phones.
The 7925G's work great, but unfortunately the 8821s are experiencing horrible issues.
They randomly drop registration and will not pick back up. This happens whether or not the device is roaming or sitting right underneath the same access point.
We are running CUCM 9.1.2 and the phone firmware load is up to date, 11.0(3)SR4
I'm new to Cisco voice so I don't know where to start troubleshooting. RTMT shows registration dropping for reason code 14
I've also seen the phone lose registration for several minutes, then randomly restart and pick registration back up, only to lose registration again.
