Welcome to Cisco Support Community. We would love to have your feedback.

- i have two WLCs 4404 and 4402 in the same mobility group and all connections seem to be ok.
- one ssid for voip.
- two 7920 phones
when i roam between the WLCs i will lose the connection.
What should i configure on the WLC??
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 126.96.36.199 or later for the controller version.
Refer to WLAN SRND for more info.
802.3x Flow Control Mode
LWAPP Transport Mode
LAG Mode on next reboot
Ethernet Multicast Mode

Over The Air Provisioning of AP
Apple Talk Bridging
Fast SSID change
Default Mobility Domain Name
both WLCs are in the same mobility group.
Firmware on 7920: 7920.4.0-03-00
Firmware on WLCs: 188.8.131.52
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.
