How to Use Message Waiting
Message waiting is a feature available only on intercom (in office) calls. This feature allows an internal caller calling another extension to leave a “message waiting” notification on the phone of the person being called. To leave a message waiting, the user will call that particular extension, and press 0 or press the “MW” soft key under the display to activate the message waiting lamp on the extension called.
When a message waiting light is placed on an extension there are two ways to clear it. One way is to return the message waiting by dialing *0 (Please note that if you have an unread voicemail, dialing *0 will play the unread voicemail first before calling back the person that left the message waiting).
Another way to clear it, is to go off hook and dial 773 (Service Code in Program: 11-11-10) which will clear the message waiting on the extension and the extension it sent MWs to. You can also have the option of going off hook and dialing 771 followed by the extension of which you wish to cancel all MWs on. Service Code 771 is an individual message waiting cancel whereas Service Code 773 is a Message Waiting Cancel All.
Many users find this feature useless and bothersome, so it is disabled by our pre-programmed defaults.
