Hello

Make sure form your wireless access points ( you have to create two SSID one for data other for voice) , wireless connectivity , configuration on your switch

interface f0/0

switchport access vlan 500   (wireless vlan)

switchport voice vlan 11

spanning-tree portfast

use the below link for troubleshooting
