No it is not just the MWI being lit later.
The person who reported it to me is my IT support. I trust her, she told me she took her messages when she got in, (1 message). Then 5 minutes later, 6 messages (earlyer messages than the first one) was in her voice mailbox. it was reported to me from other people before that, but did not spend to much time on it until this person told me it happened to her.
