We have a customer with about 40 AP1100 and without wireless controller.
These AP's are used only for voice. The customer use 7920 cisco phones.
Sometimes the customer experience some blank gap in the voice.
On the AP's the QoS is not implemented because there is only voice traffic.
Is it correct not to implement QoS on AP's? Or, even if there is only voice traffic, the QoS on AP's should be implemented?
