Anyone using 6.2209 on a 9641G without echo or static? We are hearing random complaints about it. Trying to track if they are internal or external but I have experienced it also and my experiences are all interal (but some are across the WAN). Some are internal within the same office - we have adjusted the AGC settings on phones that complain (cutting all off) and it does not matter. Not having these issues with our 9650s.
