Yes, MWI service is running. I also ran Operational History viewer in a live mode, and everything seems to be in order. When the voicemail system starts, all the prompts play properly, it says that is recording the message. When the message is done is says that
09/11/07 19:40:06, "TUI", 21223, "Information", 5, "MAS", "A message left for mailbox 1003. Message length was 5 seconds.", 1, 1003, ""
So the system supposedly saved the message, but when I later go into the voicemail to retrieve any messages, says no new or saved messages in the mailbox.
