This gives you an Operator extension with voicemail notification and General delivery notification at same extension.
After logging into the box 100, go into admin then press 6 to set up message notification. It will say not initialized, then the screen will show EXT: enter in 221. Then set the times that you want to notify the extension (8am-5pm). After a message is left in mailbox 221, it will show up in the display as 'Msg for you'. If a message is left for mailbox 100, the voicemail will actually call the ext. When the person answers the phone it will say that there is a message for "Genrai Delivery". Then in the screen you'll see a softkey Log in button, press it and log into mailbox 100 and get the message.
