Are you doing L3 mobility?

If so, would configure the voice ssid for the same VLAN on both controllers to see if that works or not.

Of course for mobility group setup, need the mac and IP configured on each contoller in that mobility group.

Ensure that 3.02 is loaded on the 7920 phones.

Would recommend or later for the controller version.

Refer to WLAN SRND for more info.

Would want to use 3.02 for 7920 as there were some key fixes in 3.01 to interoperate successfully with 4.0 controller version.
