UM8000 on a SV8100 that will not delivery messages immediately. Tried it myself last night and system shows no message in mailbox. Log into mailbox and it says no new messages. Logged back in this morning,, low and behold a message,, and the time stamp is from last night.

Tried stopping and restarting system remotely but did not have any effect.

System has been in for about a year and a half. Version: 11.2.1.3

You may want to contact NEC on this one. NEC/AVST are aware of the issue. There is actually a batch of CF cards that are defective. Contact NEC and they'll give you the dates, etc to see if your UM8000 CF card is part of the recall or not.

We've had 8-10 that we've had to replace so far.
