I have recently deployed 3800 series access points in a flex connect environment and notice I am having issues with maintaining connectivity to the wireless network on the CP-8821 phone. When roaming between access points I drop the signal completely. The access points are anchored by a 5520 controller running 22.214.171.124. I'm wondering if there are compatibility issues between the 3800 and the phone because I have another site that is anchored by a local 5520, however, the APs at that site are 3700 series but the 8821's have not encountered any problems. Any assistance would be appreciated. Thanks.

8821, for the time being, cannot roam seamlessly. It is a known issue and developers are working on it.
