Cisco 8821 Handsets

We are testing the Cisco 8821 handsets without much luck.  Phones will have weak signal, drop their registration randomly, and not roam seamlessly.  Tested all the firmware up to the most current as of today.

 

The 7925 phones work great, but are becoming hard to source now.  Heard from several vendors many people are still hvaing issues with the 8821s still.

 

Has anyone successfully deployed these?  What changes did you have to make to the VAP profile for successful utilization of these handsets?

 

We're running 6.4.4.12 on a pair of 7210 controllers, with about 140 205 APs.  CUCM is 9.1.2

Encryption? The same WLAN as the 7925s? What band?

Auth is WPA2, encryption is AES

Same WLAN, yes.

Both the 7925s and 8821s are riding on 5GHz
