Make sure the WLCs are in the same mobility group.  Make sure the mobility group shows up/up.

 

Are both WLCs in the same subnet?

 

Are you able to have a conversation when the phones are both on the same WLC?

Hi,

Thanks for response

The mobility group is same for for WLC and same subnet.

Cobversation is working fine when the the both phone are connected in same WLC.

Debabrata try the following if virtual ip didn't solve your issue.

 

1- Keep the Authentication/encryption open

2- Test making call using wireless clients on same WLC 4404 but on different AP

3-If above work then change the WLC but no WLC 4402 any other for testing purpose and test again
