Customer has a MICS 4.0 with a T-1 & 1 each digital & trunk expansion modules connected to a Rel.2.02 Startalk Flash 4 port. Sporadically, some messages are being delivered 1-2 days after they are left. For example, user will check messages at 5:00 Monday, then Tuesday they will get a new message that had been left on Monday prior to 5:00. Apparently this problem has been ongoing for a while & happens to several users. Any ideas aside from upgrading to a CP? VM & KSU have been rebooted with no affect on the issue.
