> After a SIP call is destroyed, there seems to be an excess of 487 packets floating around for about 10-15 seconds after call destruction is scheduled. Under light call volume this is not a problem. However, in a scenario where many short-duration calls are placed-received over a period of time (typical receptionist situation) excessive traffic seems to cause a "denial of service" on a Cisco IP 7900 series phone with "486 Busy here" being bounced back from a Cisco phone. Not a problem if downgrading to previous CVS version(1 week ago).
