Looking for 5760 QoS configuration example to solve 7925 phone connection problems

Hello,

we still have problems to connect 7925 phones with a 5760 controller. First we had suspected, the channel allocation because the controller had 8 of 12 APs with the same channel config. Now we use only a-standard with manual channel config but the phone says: "connection failed" and "leaving service area".

The last hope is a good QoS config for 5760 controller. Can anyone recommend a good qos config.

May be the qos config so important that a phone can not connect without it? Our wireless network is not in use by nobody so far.

 

Thanks in advance.
