Rich,   I think your Cisco phones are having trouble with the irregular 
timestamps (not evenly spaced at 20ms, but ocassionaly having jumps of 
19 or 21 ms).  Our problem is different.  It is in the other direction 
(the PSTN) side.  We do experience slight hiccups on our SPA2000s when 
timestamps jump by 19ms or 21ms but that is nothing compared with the 
lack of jitter buffer experience.
