Cisco 8821 Audio Drops / Packet loss

Hello,

 

I've a Cisco 2504 WLC with SW: 8.5.161.0 and Cisco 3802I Access Points.

The AP's are running in local AP Mode.

My Cisco 8821 Phone is on SW: 11-0-5SR3-2.

 

I've done the Configuration of WLC with the Cisco 8821 Deployment Guide.

(https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/cuipph/8821/english/Deployment/8821_wlandg.pdf)

 

All recommendations are set on WLC Software.

 

 

I have some very little Audio Drops and Voice Packets loss...

I've tried my tests with 2 meters away from the AP.

 

 

What can I do ?

If this issue only appears on 11.0(5)SR3 then I'd consider downgrading to 11.0(5)SR2.

When this issue occurs, does the phone lose wireless connectivity?

No, phone is always connected.

The drop is only a little less than one second...
