[cisco-voip] Callmanager Express with WLAN Controller and 7921 Phones

[Manoj Kalpage]

Hi All,
I am configuring CME implementation for small office. WLAN controller has
four access points configured on it. 3560 switch is configured for VLAN and
QoS as VLAN 10 is for data and VLAN 20 is for Voice. My problem here is all
7921 phones get automatically assigned to Data VLAN range of DHCP IP address
instead of Voice VLAN DHCP. But 7941 phones directly connected in to switch
get assigned to correct Voice VLAN DHCP range. The useres who use 7921 phone
are complaining that call drop middle of the conversation. Bellow is WLAN
configuration and Switch port configuration where I have WLAN controller
connected. Any information would be greatly appreciated.

Thank you.
MK
