Interesting how they pretty much made 991 unused and are using 500 as the default mailbox, ie when you enter an invalid mailbox the system will go back to or repeat 500. If DND is off it will ring the operators phone again.
Some people do different things to eliminate the 2 mailboxs for the main greeting. I prefer to use the Toshiba recommended solution of skipping 990 and using 991 as the default.
They aren't the only ones. We purchased another Toshiba telco, and all of their programming was for 990 to go to 777. Real oddball!
It pays to take the time to read the manuals!
