Hello, dear support community.
We are facing some problems with 8821 from time to time: it
- periodically loses connectivity with its wifi AP being within the range
- might freeze while transferring a call
- constantly requires IP from DHCP server (each 4 seconds)
- standby battery life is way more shorter than it climes in the datasheet
At phone configuration:
Bluetooth is disabled
Scan Mode = Auto
CUCM 10.5
