Cisco 792x iphone and AP 2802 Issue

[CSCO11177789]

Hi;

We've just replaced our all ap (app 80 piece) in network environment. Old ones is 1242ag. 

After replaced we started to get bad voice quality. Sometimes voice is interrupt during call and after 1-2 seconds it comes back.

We configured wlc setting regarding to 7921 and 7925 deployment guide. 

What we supposed to do ? Is there any best practise guide more ?

Thanks,best regards

Ok, and what version of firmware are the phones running on?

[CSCO11177789]

1.4.8.4_LOADS

Can you try to downgrade the controller firmware to 8.2.141.0 and see if it improves things?
