Cisco 7921s and CallManager 6.1

I randomly am having some 7921s drop connection with CallManager and sit at "configuring" for a period of time.  Eventually they seem to re-register, but until they do are not usable.  Any thoughts on what could be causing this?   Thanks!

Re: Cisco 7921s and CallManager 6.1

First of all it will be good to have the 7921 in one of the latest versions of FW

Then is onlyhappening to 7921 or also IP Phones?

Which Wireless infraestructure u use? U use Cisco AP/Controllers?

Is QoS configured in those APs?

Happens during roaming or when phone is on call or just sitting there?
