Message Waiting Notification Lamp

The following command needs to be set on the extension. CM 1303 > extension number (e.g. 2000) : 0 (this allows message waiting notification to be set).

To test the message waiting on an extension do the following, from a phone dial #*8 and then an extension number e.g. 2000, you should see the message waiting light come on that phone, in this case extension 2000. If you have a service feature code setup to determine switch on or off the lamp, it will likely be #*9. To turn it off dial #*9 and the extension number again.
