Anyone else getting a lot of the following log entries on your WLC? VoIP Call Failure: '12:34:56:78:9a:bc' client, detected by 'AP-Building-Room' AP on radio type '802.11b/g'. Reason: 'Call failed: TPSEC QOS Policy does not match'.
A quick search indicates this is caused by a QoS policy mismatch. These traps are from smartphones connecting to our main Secure WLAN, not VoIP phones on our dedicated Voice WLAN. I suspect these devices are trying to make calls over Wi-Fi and failing because the QoS is set to Silver (not Platinum). I've looked up a handful of the MAC addresses and they all appear to be Android devices. I have confirmed Wi-Fi calling works with an iPhone on this WLAN and no error is generated. Has anyone made adjustments to your WLAN to support and optimize Wi-Fi calling? If so, what have you done and how has it worked out?
