I have an avaya phone system and when we first moved into the building ext 10 had its message light lit up even though ext. 10 did not have any messages. I did a google search and found that there was a default mail box at ext.xxx. I logged into that mail box and there was old messages. deleted them and the light went out. I then changed the auto attendant mailbox to ext 10 and all was well. However today the light is lit and there are not messages. I called the system and left a message but it is not in mailbox 10. I forgot what that mail box number was and I can not find the post / page that said what the default system mailbox number is. How can I tell where the messages are going? Thanks
