I have WLC4400 188.8.131.52 managing AIR-LAP1131G APs and other automomous APs Aironet 1100.
The problem is when wireless IP phone 7920 moves from 1131 AP to aironet 1100, voice become one way
between this phone and other wireless phones connected to 1131 APs (WLC). It seams that the WLC is not disassociating
clients before the "User Idle Timeout" and its minimum value is 90 sec.
Please advice how can i force direct disassociation from WLC when wireless IP phone is connected to autonomous AP.
