I currenly have the WLC setup on our switches for our network and it's working fine for the laptops and other wireless devices. We just got a new Cisco phone system put in which replaced the outdated Cisco phone system. Along with that we also have the Cisco 8821 wireless phones.
I need some assistance on setting up the vlan correctly for the wireless phone. I have a vlan 10 setup and it works for the phone to connect and create/receive calls. However, intermittently the call becomes a one-way call.
I currently have it setup on Layer2 and think I need to also have it setup as a layer 3
