When calling into the mailbox from outside you receive a message "you can not record a message for user name" This mailbox is full.
When calling into the mailbox from inside it will let you record a message and then later return a non delivery receipt. It also does not light the MWI.
Is there a way to have the same message played as the outside callers hear on internal calls? Or is there a way to make the receipt light the MWI?
