Good afternoon,

we are running a couple of Cisco 7921G wireless phones on 802.11a,
connected to a Cisco Wireless LAN controller.
They run pretty smooth most of the time, but sometimes we cannot
answer incoming calls (pressing the green answer button doesn't have
any effect, phone continues to ring). This happens randomly to all of
our 12 IP phones.

Has anyone experienced similar issues with these specific phones?
Could it be a connectivity issue?

Thanks
Thomas
